Will CNG Trucks Help Fleet Owners Reduce Emissions?

Sustainability has become an important issue in the trucking industry, with many fleet owners and their customers pledging to reduce greenhouse gas emissions in the coming years. Even as diesel fuel has become “cleaner” than ever before, diesel-powered trucks are still a top cause of harmful emissions. 

In an effort to reduce their carbon footprint — and reduce fuel costs — some fleet owners are looking at alternatives to diesel, one of which is CNG.

What Is CNG?

CNG — compressed natural gas — is a processed byproduct of fossil fuels in the ground. It’s an environmentally friendly alternative to gasoline, propane, and diesel and can power trucks with CNG-compatible engines. 

According to ACT Research’s Alternative Fuels Quarterly, in the first five months of 2021, sales of Class 8 natural gas trucks rose 19% in the U.S. and Canada compared to the same time period in 2020. 

Advantages of CNG trucks

These are some of the advantages of CNG-powered trucks:

Reduced emissions

Greenhouse gas emissions are 20% lower for CNG trucks than diesel trucks. 

Lower fuel costs

In July 2022, of eight conventional and alternative fuels, CNG had the lowest price, at $3.12 per DGE (diesel gallon equivalent). It also had the smallest April-to-July price increase.

Accurate cost forecasts

CNG is abundantly available in the U.S., so it’s not subject to the price fluctuations associated with foreign oil, or major supply chain disruptions. That means fleet managers can accurately forecast fuel costs. 

Enhanced safety

CNG is non-toxic, and because it’s gas, it can’t contaminate groundwater or soil in the way liquid diesel can. In the event of a tank rupture, CNG quickly dissipates into the atmosphere.

Unlike diesel trucks, CNG trucks produce no noxious fumes — that’s a big benefit for sanitation workers and other people who work on or near Class 8 trucks. 

Quieter operation

CNG engines are 10 decibels quieter than diesel engines. A U.S. Department of Energy case study reported that after the New York City Department of Sanitation began using CNG trucks, workers could listen to the radio on routes, which wasn’t possible in diesel trucks. 

Incentives

The federal government offers funding and grants for municipalities and public institutions seeking to switch to CNG-powered trucks. In Indiana, the City of Portage Street and Sanitation Department replaced its garbage truck fleet with CNG trucks, thanks to the Volkswagen Environmental Mitigation Trust. 

Barriers to CNG truck adoption

Despite the obvious benefits of natural gas trucks, there are some barriers to widespread usage.

Fewer fueling stations

CNG fueling stations are located mostly in densely populated areas. Depending on transit routes, some fleets may be unable to use CNG trucks. 

Source

Lack of trained technicians

CNG engines run cleaner than diesel engines, which means fleets may need fewer scheduled service appointments. But finding CNG-trained technicians and shops could be a challenge. 

Shops that service CNG engines must be CNG-approved and have fire marshal certification for proper ventilation. Only certified high-pressure technicians can work on the fuel tanks, and fuel system inspectors must have CNG-specific training.  

Cost

Businesses that don’t qualify for grants may find the cost of CNG trucks prohibitive. Conversion kits for heavy-duty vehicles start at $1,875 and don’t include the fuel tank. New Class 8 tractors cost about $170,000, compared to $120,000 for a diesel tractor. 

Technology for Better Trucking

Whether you’re switching to CNG or sticking with diesel, there are steps you can take to lower your fuel costs, fuel usage, and emissions.

TruckWings by TruckLabs is a drag-reduction device with aerodynamic panels that close the gap between tractor and trailer when speed exceeds 52 mph. The panels deploy automatically, and retract when speed drops below 50 mph. This durable, low-maintenance solution takes less than two hours to install and works for most tractors — both diesel and CNG.

Semi Truck Emissions Regulations: What Fleet Owners Need to Know

Class 8 trucks are responsible for about a quarter of the greenhouse gas emissions generated by the U.S. transportation sector. That amounts to over 400 million metric tons of carbon dioxide (CO2 ) emitted each year.

Diesel engines contribute to pollution by creating particulate matter, a mix of fine particles and liquid droplets that can become lodged in the lungs and irritate eyes and skin.

U.S. fleet owners and trucking companies face increasing pressure from both national and state agencies to reduce their trucking emissions footprint and keep up with changing environmental standards. Earlier this year, the Biden administration proposed stronger emissions regulations for heavy-duty vehicles, with the U.S. Environmental Protection Agency (EPA) proposing that the industry cut up to 90% of NOx emissions per truck by 2031. 

Transitioning to electronic vehicles (EVs) could help combat pollution and comply with government regulations, but that’s simply not financially possible for many fleets. 

In this post, we’ll review some of the main semi-truck emissions regulations and how they’ve evolved. We’ll also look at a solution fleet owners can implement to meet these standards without transitioning the entire fleet to EV.

The Evolution of Semi Truck Emissions Standards

U.S. emission standards for heavy-duty compression ignition (CI) engines have evolved over the past 50 years. The EPA develops these regulations, with California’s Air Resources Board (CARB) setting additional standards for that state.

Here’s a brief timeline of how emissions standards have played out for heavy-duty vehicles since 1970:

1970: Congress passes The Clean Air Act, which mandates a 90% reduction in automobile emissions by 1975. That same year, President Nixon established the EPA, the agency responsible for regulating motor vehicle pollution. Per the EPA’s website:  

“New cars must meet EPA emission standards for hydrocarbons (HC), carbon monoxide (CO), nitrogen oxide (NOx). The law also directs EPA to set health-based ‘National Ambient Air Quality Standards’ for six pollutants.”

1971: The EPA officially starts testing the fuel economy of all vehicles as a precursor to informing consumers about vehicle gas mileage.

1974: The EPA begins limiting heavy-duty engine emissions of particulate matter (PM), CO2, hydrocarbons (HC), and NOx. 

1985: The EPA sets strict standards for NOx emissions from heavy-duty engines and for PM from heavy-duty diesel-powered trucks and buses. 

1990: To help trucks and buses meet 1985 emissions standards which would soon become active, the EPA sets limits on diesel fuel sulfur content. Congress amends The Clean Air Act, requiring additional reductions in emissions of HC, CO, NOx, and PM.

1997: The EPA finalizes emission standards for HC, CO, NOx, and PM.

2000: The EPA launches a national program to regulate heavy-duty vehicles and their fuel as a “single system.” 

2005: The EPA finalizes durability procedures that help manufacturers predict emission levels for certain types of new trucks and vehicles at the end of their useful lifespan.

2011: The EPA and National Highway Traffic Safety Administration (NHTSA) introduce regulations for improving the fuel efficiency of heavy-duty trucks and buses and reducing their greenhouse gas emissions.

2015: The EPA and NHTSA propose greenhouse gas and fuel economy standards for model years 2018-2027 medium- and heavy-duty trucks.

Dieselnet breaks down EPA and California emission standards for heavy-duty CI engines from 1974 through 2027, as follows:

EPA Proposes Tougher Emissions Rules 

As anyone in the trucking industry knows, heavy-duty trucking will likely rely on internal combustion for at least the next decade. To further curb emissions and make existing trucks cleaner, the EPA has proposed tougher emission rules for existing heavy-duty vehicles and engines. 

These rules, which would come into effect starting in 2027, aim to cut NOx emissions up to 60% by 2045. Another proposed EPA rule impacts greenhouse gas (GHG) emissions standards for heavy-duty vehicles starting in 2027. 

The rules are part of the EPA’s Clean Trucks Act (CTA). Introduced in 2021, the rules set new standards for criteria pollutants in the trucking sector and update GHG emissions standards for heavy-duty vehicles starting with model year 2030.

California’s regulations are even stricter, requiring new trucks, including big rigs, to achieve zero emissions by 2040. This regulation, proposed by CARB in August 2022, requires large trucking companies to convert existing fleets to zero-emission vehicles and achieve zero emissions by 2042. CARB’s Advanced Clean Truck (ACT) also requires truck manufacturers to sell 30% of their stock as EVs starting in 2024.  

These proposals mean that owners of big-rig trucks must become more aware of how their fleet contributes to pollution and what steps they can take to reduce emissions.

Cost a Major Concern for Fleet Owners

Fleet owners, truck industry groups, and owner-operators are understandably concerned about the potential costs of new and upcoming regulations. The implementation of stricter emission standards could cost manufacturers between $19 and $31 billion by 2045, though the EPA estimates net benefits of over $200 billion.

In March 2022, American Trucking Associations President and CEO Chris Spear voiced the industry’s support for reducing air pollution by curbing GHG and NOx emissions as long as the regulations wouldn’t hurt “the reliability  of the trucks and trailers purchased or impose unreasonable or unworkable costs on the industry.” 

In response to concerns about high costs to fleet owners and owner-operators, the Biden Administration had already begun rolling out government subsidies via The Supporting Trucking Efficiency and Emission Reductions (STEER) Act. 

What is The STEER Act?

The STEER Act, formally introduced by U.S. Rep. Rodney Davis in July 2021, is a voucher program that helps cover the cost of retrofitting heavy-duty trucks with technology that reduces emissions. 

The STEER Act Coalition was formed in 2022 to further the bill’s passage. Currently, the coalition, of which TruckLabs is a member, is reaching out to legislators. Our aim is to get the STEER Act passed as a standalone bill or as part of President Biden’s Inflation Reduction Act — a bill that, among other measures, allocates funds to help reduce carbon emissions by 40% by 2030.

If passed, The STEER Act’s total budget would be $500 million, spread over five years. 

Under The STEER Act, the per-unit voucher size decreases incrementally based on the size of the fleet, as follows:

  • 10 trucks or fewer: $4,000 or 75% of total cost per unit
  • 50 trucks or fewer: $3,500 or 72.5% of total cost per unit
  • 100 trucks or fewer: $3,000 or 70% of total cost per unit
  • >100 trucks: $2,500 or 67.5% of total cost per unit

In its overview of the STEER Act, the EPA’s Office of Transportation and Air Quality writes:

“This legislation aims to accelerate market penetration of active emission-reducing technologies like TruckWings for Class 8 trucks by creating a program to significantly reduce the up-front cost of purchasing and installing these technologies.”

“Rather than the government picking winners on the fuel source, let’s make trucks more efficient and help reduce emissions on diesel trucks today, while at the same time enabling an electric future.”

Sustainable Trucking Trends and Tech to Watch in 2023

Sustainability

Mitigating waste, conserving resources, and reducing pollution are not new challenges for the trucking industry. Commercial trucks comprised nearly 30% of transport emissions in 2018, making the sector one of the fastest-growing sources of greenhouse gases in the United States. Given the increase in public awareness about the impact of climate change, sustainable trucking is now a trending topic.

The trucking industry is under increasing pressure to reduce its emissions. This pressure comes from the government and the public, but it also comes from truckers.

In a study by digital freight network Convoy, 61% of surveyed drivers said that climate change is of some or a great deal of importance. 

In this post, we’ll look at four sustainable trucking trends and technologies that could help minimize emissions.

4 Trends Driving Sustainable Trucking

With more than 300 companies signing the Climate Pledge to achieve carbon net-zero status by 2040, sustainable trucking is top of mind for many businesses.

As part of its study, Convoy surveyed dispatchers, drivers, and owner-operators from 700 SMB trucking companies. Convoy’s goal was to understand the current state of sustainability in trucking.

The findings revealed four key trends affecting sustainable trucking:

1. New (And Not So New) Government Regulations

Government regulations are the most significant driver of sustainable trucking practices.

Just over 25% of respondents in the March 2022 Convoy survey listed regulations as their top reason for reducing carbon emissions, up from 19.2% in August 2021. New environmental regulations focused on curbing emissions are currently under consideration at the national level. And state-level regulations, like the California Air Resources Board (CARB)’s zero emissions goal, are a factor driving sustainable trucking practices. 

Here are a few to keep in mind:

  • In April 2022, the federal government announced new vehicle fuel economy standards for model years 2024-2026. The measures will require an industry average of 49 mpg for new passenger cars and light trucks by 2026. The rule aims to increase fuel efficiency by 8% annually in 2024 and 2025 and 10% in 2026.
  • The California Air Resources Board (CARB) is working towards zero emissions for medium and heavy-duty fleets by 2035. The new regulation will significantly impact the transportation industry as early as 2024, with California planning to restrict fleets from deploying non-zero emission vehicles in drayage operations starting Jan.1 of that year.
  • SmartWay, an EPA program introduced in 2004, focuses on reducing emissions across the supply chain by enabling transport companies to track, document, and share fuel use and freight emissions. SmartWay partners enjoy many benefits, including help demonstrating their commitment to improving freight sustainability, and reducing CO2, NOx, and PM emissions.

2. Rising Diesel Costs

Diesel costs are high and not likely to decrease any time soon.

Three-quarters of all commercial trucks use diesel, moving nearly 70% of America’s freight tonnage. Since this likely won’t change in the next 10-20 years, trucking companies need to find ways to cut fuel consumption to reduce costs and emissions.

Nearly all of the nation’s largest tractor-trailers — class 8 trucks — are powered by diesel, and about 75% of small-to-medium-duty commercial trucks use diesel. Depending on your state, a gallon of diesel averages $5 to $6, meaning the average cost to fill the tank can range from $700 to $1,400, depending on the truck’s size.

This makes achieving maximum fuel efficiency a top priority for truckers and trucking companies.

3. More Pressure to Take Action

Awareness of climate change and public pressure are still big factors driving sustainable initiatives for many in the trucking industry.

In Convoy’s survey, 38% of respondents reported feeling pressure to reduce carbon emissions, up from 35% in 2021. Respondents cited government regulation as the top reason for feeling pressure to reduce carbon emissions, second to awareness about the environmental impact of emissions.

 

4. Efforts to Reduce Empty Miles

Convoy’s research found that 35% of truck miles are empty miles, with drivers driving, on average, between 100 and 400 miles empty.

Reducing empty miles by just 1% saves over 100 gallons of fuel. It’s why nearly 93% of respondents in the Convoy survey said reducing empty miles is moderately important, important, or very important to their business.

Empty miles have a huge environmental impact, contributing to 87 million metric tons of carbon emissions annually. But they also represent an opportunity when it comes to reducing emissions and improving sustainability in trucking.

 

Sustainable Trucking Technologies

Promising new technologies like active aerodynamics, alternative fuel vehicles, and telematics can help trucking companies reduce emissions, comply with government regulations, and save money.

We unpack all three below.

 

1. Active Aerodynamics

Active aerodynamics is a term commonly associated with improving the fuel economy of cars by reducing drag, and it can also apply to trucks.

Due to the considerable size and weight of trucks, semi-truck aerodynamics are more challenging to achieve. Recent research by the U.S. Department of Energy (DOE) revealed that a truck engine uses 85% of the energy it produces to overcome aerodynamic drag and rolling resistance.

To fix this, TruckWings, a tractor-mounted aerodynamic device created by TruckLabs, decreases downstream turbulence and drag. The device eliminates higher crosswind angles in the tractor-trailer gap by controlling airflow around the cab.

TruckWings works without driver interaction by extending winglets from the side of the truck based on vehicle speed and smart sensors, automatically unfolding once highway speeds reach 52 mph and retracting when speed goes below 50 mph. This can result in fuel savings of up to 4.1% — the equivalent of 20,000 pounds of CO2 per year.

2. Alternative Fuel Vehicles (AFVs)

With diesel costs and regulations around emissions, many trucking companies are turning to alternative fuel vehicles (AFVs). AFVs include electric, hydrogen-electric, and renewable natural gas vehicles.

They emit just under 4,100 pounds of CO2 equivalent annually versus the 11,435 pounds of CO2 emitted by gas vehicles. AFVs are cost-prohibitive for many SMB trucking companies, with an up-front cost per vehicle of $200,000 to $800,000, versus $40,000 to $120,000 for the base model of a new diesel-powered semi-truck.

For this reason, equipping your existing fleet with tools to help reduce drag and improve fuel economy is a more cost-effective way to reduce emissions in the short term.  

 

3. Telematics in Trucking

Telematics is essential for many trucking companies looking to reduce emissions and improve sustainability. 

The software uses sensors, GPS technology, and other data-tracking technologies to help companies: 

  • Track their vehicles in real time
  • Optimize routes to reduce empty miles
  • Identify patterns and areas for improvement

Data collected includes:

  • Fuel consumption
  • Real-time truck location
  • Idling time

 

Sustainability Challenges in Trucking

Sustainability challenges are becoming synonymous with business challenges for truckers.

Pressure is mounting for trucking companies to prove their commitment to reducing carbon emissions and identify problematic practices within the supply chain.

Understanding how scope 1, 2, and 3 emissions impact the environment can help you make better choices for your business and the environment.

Here’s a brief breakdown of each type:

  • Scope 1: Direct emissions from company-owned or controlled sources
  • Scope 2: Indirect emissions from using electricity, heat, or steam
  • Scope 3: Other indirect emissions from the entire value chain

The best way to address Scope 3 emissions is to partner with sustainable trucking companies committed to reducing their emissions.

 

The STEER Act Can Help

US Rep. Rodney Davis introduced the Supporting Trucking Efficiency and Emission Reductions (STEER) Act in 2021.

It’s a $500 million voucher program focused on helping truckers and trucking companies retrofit their existing class 8 trucks with fuel-efficient technologies.

The STEER Act aims to help fleet owners reduce emissions and move towards more sustainable practices by incentivizing emission-reducing technologies. So even if you aren’t ready to move to AFVs, you may qualify for a voucher to cover the technology needed to retrofit your existing fleet.

 

Examples of Sustainable Trucking Companies

Here are three examples of trucking companies prioritizing sustainability, starting with Ryder System, Inc., a company that conducted a recent test of our TruckWings technology. 

 

Ryder System, Inc.

Ryder partnered with TruckLabs to conduct a 60-truck on-road test of TruckWings.

The controlled pilot fuel test assessed whether TruckWings could improve Ryder’s fuel economy and reduce the environmental impact of its fleet of over 200,000 trucks. Ryder compared the relative performance of a truck before and after installing the technology.

After evaluating the results, Ryder realized an improvement of over 4% in net mpg.

 

Werner Enterprises

Werner Enterprises is a US-based transportation and logistics company that uses technology to reduce CO2 emissions across its fleet of 8,000 trucks and 24,000 trailers.

Werner uses automated manual transmissions to boost fuel economy by 1-3%, predictive maintenance to monitor performance and keep trucks at maximum efficiency, and GPS trailer tracking to increase hauling efficiency. They’ve also begun piloting solar panels on their trucks to help extend battery life and reduce jump-starts.

 

DHL Express

DHL Express, headquartered in Germany, wants to reduce greenhouse gas emissions to below 29 million tons by 2030.

They aim to reach net-zero emissions by 2050. In addition to addressing Scope 3 emissions by auditing service providers along the supply chain, the company has begun retrofitting its fleet of medium- and heavy-duty trucks with solar panel mats that regulate the transfer of energy from the alternator to the battery.

The mats, expected to reduce greenhouse gas emissions for each vehicle by 2,000 pounds annually, also have sensors that collect data on fuel and emissions.

 

A Pathway to Sustainability

Sustainable trucking leaders show that there are many ways to reduce your emissions.

From active aerodynamics to solar panels to ATVs, the options to reduce your carbon footprint are numerous. As government, consumer, and industry awareness about the industry’s impact on climate change grows, so will the pressure on trucking companies to mitigate their emissions.

Products like TruckWings can help your company take the first steps towards reducing emissions and fuel costs. The companies that don’t begin to invest in more environmentally-friendly technologies will fall behind as the industry moves towards a more sustainable future.

A Quick Guide to Improving Tractor Trailer Aerodynamics

semi truck aerodynamics

Did you know that improving trailer aerodynamics can significantly impact drag and fuel efficiency?

Aerodynamic drag is responsible for 65% of the energy used while pulling a trailer. That’s why more fleets are turning to products like trailer aerodynamic products to help reduce drag and save money on fuel costs.

But what are trailer aerodynamics, exactly?

And which product is right for your fleet?

Answering these questions requires understanding the effects of aerodynamic drag on tractor-trailers and the different types of products available to reduce it.

What Are Trailer Aerodynamics?

Trailer aerodynamics refers to the study of how air flows around and over a trailer.

When a truck moves, air resistance (or drag) slows it down and uses up fuel. Reducing drag can lower fuel consumption by up to 12%. This would save more than $10 billion in diesel fuel per year.

The Main Points of Drag on Tractor Trailers

To understand how to reduce drag, it’s essential to know where it comes from.

There are three main points of drag on tractor-trailers:

  • Back of the trailer near the doors: When air circulates around a trailer, it forms a vortex behind the rear door, causing a significant decrease in air pressure.
  • Front of the trailer near the gap: One of the worst low-pressure areas on a truck is the gap between the cabin and trailer.

Addressing these areas can significantly improve trailer aerodynamics.

Airflow Simulation

Products and Devices to Reduce Tractor-Trailer Drag

Aerodynamic devices are effective at reducing drag and improving fuel efficiency.

And the faster the speed, the more efficient they become. Many products and devices on the market can help reduce drag.

  • Trailer fairings: The trailer fairings (or skirts) keep the wind from blowing under the trailer and into the bogie. They work best when they start from the landing gear and end at the front face of the front trailer axle, close to the ground.
  • Wheel covers and mud flaps: Wheel covers are devices inserted into the wheel that help direct airflow around the tires. Mudflaps are installed behind the wheels and help deflect air away from the undercarriage.

When choosing an aerodynamic device, it’s important to remember that many will complement each other. For example, using trailer tails with wheel covers further reduces drag.

Of course, fleet owners must consider the unique needs of their operation when choosing products.

Trailers Are Only Part of the Equation

While trailer aerodynamics are important, they account for only some of the drag that impacts fuel efficiency.

The front tractor section also accounts for a significant amount of drag (about 25%). To address this, some truck manufacturers are exploring a more aerodynamic design for the front of the truck.

Some solutions include adding pedestal door mirrors and sloped-front windshields.

The gap between the cab and trailer also accounts for about 25% of the overall drag. High-speed air rushing in causes a low-pressure area which then drags on the tractor and decreases fuel economy.

Closing the gap would result in a decrease in airspeed and less turbulence downstream. Increased pressure at the back of the cab would decrease overall drag, especially where crosswinds are strong.

For fleet owners, this could mean a significant decrease in fuel consumption and savings amounting to millions of dollars each year.

Learn how Ryder Systems saved 4.1% on fuel with TruckWings.

Improve Trailer Aerodynamics and Fuel Efficiency

Cutting emissions and fuel costs is a high priority for trucking fleets.

That’s why many fleet owners are investing in trailer aerodynamic devices.

There are two types of trailer aerodynamic devices:

  • Hardware-only devices that require driver interaction.
  • Smart products that are automated and require no driver interaction.

TruckWings and TrailerTails are two devices that are sometimes confused, but there are key differences between them. TrailerTail (discontinued) was a hardware-only device installed on the back of the trailer that required the driver to close it manually. TruckWings is the only fully automated, tractor-mounted device that works without interaction, allowing for the best driver experience.

By automatically closing the gap between the cab and trailer, the device:

  • Improves stability
  • Increases fuel efficiency
  • Reduces drag

TruckWings also:

  • Operates in two positions — closed when the truck travels fast on an open highway and open when going slow or making turns
  • Uses smart sensors to track carbon and fuel savings
  • Provides uptime reporting

FAQ

How do I reduce drag on my truck trailer?

There are several ways to reduce drag on your trailer, including:

  • Adding trailer fairings (or trailer skirts) to keep the wind from blowing under the trailer and into the bogie.
  • Installing mudflaps and wheel covers to help direct airflow around the tires.
  • Adding a trailer tail to alter the airflow as it leaves the trailing edge of a truck’s side and top surfaces.

Why do truck trailers have wings?

Wings help keep the trailer more stable and improve fuel economy.

Do truck wings work?

Yes, they are an effective way to reduce drag and fuel costs. In fact, TruckWings provides potential fuel savings of 3-6% mpg with 12-18 months ROI resulting in millions of dollars saved per fleet.

What Fleet Owners Need to Know about ESG Reporting

The SEC’s new climate disclosure rule, proposed in March 2022, has paved the way for the broadest federally mandated corporate ESG data disclosure requirement ever. The rule would require public companies to provide certain climate-related financial data, and greenhouse gas emissions insights, in public disclosure filings. That has put pressure on a host of industries, including transportation, to seek faster ways to reduce emissions as investors, shippers and consumers demand more ESG reporting and greater sustainability measures.

Pressure Mounts to Lower Emissions, Report Results

Companies have stepped up their Environmental, Social and Governance (ESG) reporting, or sustainability reporting, as global climate change measures have increased the demand for industries to lower greenhouse gas (GHG) emissions. 

Companies deemed more socially responsible are now far more appealing to investors and consumers. In response to the global cry for serious climate change response, more than 300 businesses have taken the Climate Pledge, including those in the transportation industry, to achieve net-zero carbon emissions by 2040 across its operations. That’s a decade ahead of the Paris Agreement, which requires countries to reduce emissions by 45 percent by 2030 and reach net zero by 2050.

In the United States, the transportation industry stands as one of the leading contributors of air pollution. Carbon dioxide (CO2) creates the vast majority of GHG emissions and major sources of CO2 include fossil fuel combustion. In fact, although freight trucks make up only 10 percent of the vehicles on the road, they produce 25 percent of all greenhouse gas emissions.

Now trucking fleet operators are feeling the pressure to produce ESG reports, especially data around emissions, and work more quickly to lower emissions and reduce their carbon footprint.

So, What is ESG Reporting Again?

ESG impacts represent a fairly broad umbrella of activities, and fleet operators are already doing many things that qualify, including using alternative fuels, running newer, lower-emission trucks, using products and technology solutions that create better freight efficiency, and even using energy-saving and recycling efforts at trucking facilities.

Trucking companies also are monitoring their social impact, which takes into account people and culture. Employee engagement initiatives and better standards for drivers fall into this category, along with monitoring labor standards among suppliers, data protection and privacy, and gender and diversity.

Good governance practices ensure transparency in operations and cover the procedures that help fleet owners stay ahead of violations, adopt sound internal systems of control, and maintain strong leadership.

ESG reporting makes public or available a list of Environmental, Social and Governance activities a transportation company is engaged in, and the impact those activites have had on reducing emissions. Socially responsible investors, shippers, and even consumers may use that data to make business, capital and purchasing decisions.

There is currently no law that mandates ESG disclosure for non-listed companies, but expectations have been raised for fleet operators and there are many ways to track ESG impacts. The three so-called pillars of ESG focus on people, process, and product.

Walmart Canada is offering carbon-neutral last mile delivery for e-commerce purchases. Ikea, which handles two million shipments a year, has set a goal to be climate positive by 2030 and has deployed transportation management systems to reduce trucking emissions. The retail giant has produced high-level reports describing activities related to its climate journey.

Trucking fleet operators also have Scope 1, 2 and 3 carbon emissions they can report and, by far, emissions controls and reductions remain the trucking industry’s largest focus when it comes to ESG reporting.

As Easy as Scope 1, 2 and 3

Source: https://pba.umich.edu/scopes-of-carbon-emissions-explained/

Tracking scope emissions opens ways to lower overall environmental impact and improve the bottom line.

Scope 1 emissions cover direct emissions generated from owned or controlled sources, including fleet fuel use.

Scope 2 emissions are indirect emissions from the generation of purchased energy, including from cooling systems, electricity, heating, and steam. Scope 3 emissions are the result of activities from assets not owned or controlled by the reporting organization, but that the organization indirectly impacts.

Scope 3 emissions could include those produced by business travel, employee commuting, waste disposal or the emissions generated by purchased goods and services or transportation and distribution.

Reporting results of emissions-reducing activities can be a part of good ESG reporting.

It’s Electric – The Promise of EV Looms, But What About Now?

Trucking industry leaders agree that trucks of all sizes are ready for electrification, but large-scale fleet conversions to EVs across the transportation industry are still years away. With trucking accounting for a quarter of all U.S. carbon emissions, the move to zero-emission vehicles will deliver tremendous benefits.

But other new technologies, products, and practices can assist the trucking industry directly with reducing carbon emissions in the meantime and produce a measurable impact right away. Here are some of those go-to resources:

  • Aerodynamics: Products like TruckWings can significantly increase fuel efficiency. The tractor-mounted aerodynamic device automatically closes the gap between cab and the trailer, reducing drag. Use of the device can mean 3-6% fuel savings which can lead to millions of dollars in savings per fleet. TruckWings is the only fully automated aerodynamic device that works without driver interaction.
  • Tracking Vendors: Make sure vendors and suppliers are jumping on board with their emission-reducing practices. Do business with companies and partners that are actively shrinking their carbon footprint.
  • Alternative Fuels: Alternative fuels which have the potential to be used in trucking include biodiesel, gasoline, electric trucks, natural gas, and hydrogen fuel cells.

How to Get Started on ESG Reporting

Even if you don’t need an official ESG report for investors yet, it is a good idea to develop some sort of documentation, maybe even a website page, to show your ESG activities. Here are four quick tips to consider:

  1. Have an ESG Strategy – Develop a sustainability strategy and set short-term and long-term goals. Work with different departments to gather input and buy-in on the strategy.
  2. Decide on a Reporting Framework – There are still no right or wrong ways to produce ESG reports, but determine how you will consistently track, collect and report ESG activities and use a consistent framework. Consider who will be viewing the reports and what information they will most need.
  3. Reliability and Transparency – Decide on which activities you will report and ensure that consistent, reliable data can be collected. All ESG activities should be transparent both internally and to vendors and partners. Include activities that can be reliably measured.
  4. Watch Competitors – Pay attention to how your competitors are tracking and reporting ESG and tear a page from their playbook, or make sure your reporting is at industry standard.

ESG Reporting Delivers On-Time Benefits

Despite the pressure fleet owners and operators are feeling about carbon emission reduction and reporting, there are simple ways to demonstrate sustainability and get started now with improved practices and policies.

TruckWings and TrailerTail: A Case of Mistaken Identities

There are two aerodynamic devices in the trucking industry that are sometimes confused: TruckWings and TrailerTails. Yes, they’re both aftermarket accessories designed to help trucks reduce drag and improve fuel efficiency and have both been proven successful at achieving fuel savings. And it’s true each has anatomical names. But, that’s pretty much where the similarities end.

The products are significantly distinct from one another: They’re mounted on different parts of the truck. One’s fully automatic and the other isn’t. And most importantly, TruckWings is available pre-delivery via all major OEMs while TrailerTails is no longer available.

The parallels between the two products are just enough to have caused some confusion in the marketplace. The following table was developed to make distinctions clear—and hopefully dispel the notion that TruckWings and TrailerTail are one and the same.

5 Ways to Improve Semi-Truck Aerodynamics and Reduce Fuel Costs

Rising fuel prices – topping off at more than 75 percent higher than last year – have left the trucking industry scrambling for solutions to reduce fuel costs and improve the efficiency of their fleets.

Diesel prices have reached record levels and not since the 1970s has there been a tougher time to manage fuel hikes and keep trucks running.

The seemingly endless trend in the wrong direction has trucking operators turning their attention from the inside of the tank to the outside of the truck, reconsidering truck aerodynamics and new advances in products and devices that curb their losses.

The Impact of Aerodynamics on Fuel Economy

Semi-truck aerodynamics plays a large role in how fuel efficient a truck can be when traveling at high speeds along an interstate highway.

At highway speeds, a semi-truck consumes more than half of its fuel by pushing through air resistance created by the size and shape of the semi-truck and trailer. This so-called aerodynamic drag decreases fuel efficiency.

That drag is created along multiple points of the truck and trailer, including the front of the truck, the gap between the trailer and the tractor, the sides and underbody of the trailer, and the back of the trailer. The smoother the airflow around those points, the lower the drag.

Improving aerodynamics can deliver significant fuel cost savings. In fact, industry reports indicate that using multiple devices to reduce aerodynamic drag can reduce trucking industry fuel consumption by more than 12 percent – or some $10 billion in diesel fuel costs.

The Most Common Drags

Trucking companies have popularized many products over the years that improve semi-truck aerodynamics, including streamlined shields, trailer skirts, trailer tails, and devices that cover the gap between the tractor and trailer.

All are directed at reducing the percentage of drag created by each aerodynamic-resistant component of a truck and trailer.

Among the leading offenders on a truck, when it comes to wind resistance, is the gap between the tractor and the trailer, which can produce 25 percent of the overall drag. Any gap of 18 inches or more between the tractor and trailer can produce increased air resistance, researchers say. Covering the gap can reduce drag by as much as 9 percent.

The front end of a tractor also produces a significant amount of drag or about 25 percent. Many truck manufacturers are eyeing the front of the truck for more aerodynamic design, including sloped front windshields and pedestal door mirrors.

All along the side of a semi-trailer, aerodynamics are impacted, along with the underbody. Combined, that’s another 25 percent of overall drag created by a tractor-trailer rolling down a highway.

Finally, the back of the trailer creates yet another point of drag when air gets trapped around the tail.

5 Easy Ways to Improve Semi-Truck Aerodynamics

Devices on the market today can create much-improved aerodynamics on semi-trucks and are readily available. Here are five leading ways to boost fuel efficiency.

  1. Reduce the gap between truck and trailer: Using an aerodynamic device to cover the gap can significantly reduce drag and improve fuel efficiency. Trucking industry giant Ryder System, Inc. partnered with us to use our TruckWings device, which delivered them a fuel saving of 4.1 percent. TruckWings automatically deploys at speeds above 52 mph, covering the gap without any distraction to the driver, and retracts when speeds drop below 50 mph, allowing for safe maneuverability on surface streets.
  2. Reduce airflow underneath: Side skirts reduce airflow underneath trailers, leading to fuel savings of more than 4 percent, according to manufacturers.
  3. Minimize tail drag: Trailer tails, or “boat tails” that reduce turbulence can knock fuel costs down by around 6 percent for semi-trucks traveling at 65 miles per hour
  4. Check your wheels: Wheel covers allow air to flow past the tires, reducing aerodynamic drag.
  5. Make mud flaps aerodynamic: Switch from heavy, solid rubber flaps to slotted mudflaps, which allow air to pass through them.

Improve Aerodynamics, Cut Fuel Costs

In the face of unprecedented fuel costs, fleet owners are finding a growing number of options on the market for improving truck trailer aerodynamics and creating fuel-efficient designs.

Leading the way in preventing costly wind resistance is TruckWings, providing an accessible, automated aerodynamic option that can significantly trim fuel costs across an entire fleet.

How Innovation is Keeping Fuel Costs Down, Drivers Comfortable

TruckLabs VP of Product Andrew Kelly sees an increasing need for truck fleet operators to reach emissions reduction goals while tackling increased fuel costs and driver shortages. Thankfully, technology and product innovations are now speeding solutions for keeping fleets online and drivers comfortable. Kelly shares his insights on the latest innovations sparking the future for fleets and top solutions helping the trucking industry face unprecedented disruption.

Q: What trends and innovations are most exciting for the trucking industry, especially against the backdrop of ongoing challenges, including rising fuel costs and driver shortages?

A: Sensor technology, the enabling of IoT through connected devices, and the pursuit of aerodynamics are among advancements paving the way for the future of trucking fleets, said Kelly, who oversees the design of TruckWings, a key product offering from TruckLabs. The tractor-mounted active aerodynamic device automatically closes the gap between a truck cab and the trailer at highway speeds to reduce drag, improve handling, and save fuel.

Trip data that can now be collected along a truck’s route is providing increased visibility into how to optimize routes, economize on fuel, improve driver satisfaction, and increase the operational efficiency of entire fleets. New platforms can measure a truck driver’s performance while accounting for real-world complications, including weather, traffic and load. Data systems and sensors provide minute-by-minute data that can pick apart stories about truck performance to see how a truck operates, noted Kelly.

Truck design and the adoption of leading-edge aerodynamics are also shaping the future of the industry, Kelly added. Aerodynamics are one of the most cost-effective means of improving a truck’s efficiency. Improvements in aerodynamics for trucks are going beyond fuel efficiency design to the frontier of EV capabilities.

Q: What does the future hold when it comes to the adoption of electric truck fleets?

A: For sure, we can hear the silent roar of electrification, said Kelly. Designing electric trucks addresses the dependence on fossil fuels and the increasingly important issues of carbon emissions and fuel efficiency. But, there is a lot of apprehension from an operational standpoint, and massive adoption is still well around the corner, Kelly noted.

Aerodynamics is critical for America’s trucking fleets. While EV manufacturers continue to address issues around battery weight and range, aerodynamics is one of the most critical factors in achieving range targets in electric trucks. Aerodynamic losses are irreversible in EVs, whereas energy spent on acceleration can be partially recovered with regenerative braking in trucks, for example, Kelly said.

We see the aerodynamic choices of passenger car EVs on the market today that stand apart, including flush door handles, digital side view mirrors, and 3D wheel covers. Truck manufacturers have to make the same leap in aerodynamic efficiency to hit their range targets for market appeal. As manufacturers continue to put R&D investments into battery technology, the first generation of electric trucks will look much like their diesel counterparts. That leaves room for aerodynamic design to help in this first stage of adoption.

Right now the fastest way that a truck manufacturer could reduce drag on an existing truck model is to apply TruckWings, said Kelly.

Q: How does the TruckWings product address fuel efficiency and aerodynamics, while making the lives of fleet managers easier?
A: TruckWings closes the gap between the truck cab and trailer, where airflow commonly creates drag and stability issues. The product can be quickly installed and requires zero driver input to operate. Using vehicle speed and a smart sensor to detect trailer clearance, the patented folding panel design automatically deploys and retracts for easy use and maximum maneuverability without being prone to damage from user error. Common aerodynamic product offerings on the market today include long side extenders, which can limit turning radius during in-town driving. TruckWings retracts automatically at speeds under 50 mph without driver input, so trucks can be easily maneuvered for all driving conditions.

TruckWings traces its origins to a visit company founder Daniel Burrows made to a truck stop. Inspired by his work with climate change, Burrows noticed the gap between the truck and trailer and wondered if there was a better way to create energy and performance efficiency for commercial trucks.

The latest generation of the TruckWings solution automatically fits about 90% of trucks that are being manufactured and can be customized for others. That allows TruckLabs to buy parts in bulk to have on hand for delivery and service for any make and model of truck and cut down on lead time.

TruckWings works for all major OEM tractor models, a symbol that our customers have already pushed the limit and are keen on what makes a tractor most efficient and are looking to unlock best in class trucking aerodynamics, said Kelly.

Q: How do aerodynamic solutions for trucks help with driver retention?
A: Driver shortages have kept the trucking industry scrambling as supply chain and logistics issues have gone from one-time “black swan” events to an ongoing global challenge. Trucking fleet operators have responded by working to improve driver retention and the comfort of long-haul drivers.

Aerodynamic solutions like TruckWings can help. Product reviews and studies show that TruckWings helps reduce buffeting and improves the stability of a truck traveling in crosswinds, which can reduce fatigue associated with fighting crosswinds. Drivers also have reported feeling that TruckWings helped with straighter driving, said Kelly. The product operates automatically, so drivers don’t have the hassle of another device to maintain or operate.

Trucking companies today are looking for just about anything that can keep drivers happy and comfortable, but also need to take advantage of the latest technology to improve fleet operations and stay competitive.

So much is changing for the industry, yet the basics of driver comfort, safety and optimizing routes remains at the core of doing good business.

Economic & Environmental Benefits of The STEER Act

Incentivizing use of emissions-reducing technologies in the trucking industry

Technologies have been developed in recent years to actively control aerodynamics and rolling resistance, and otherwise increase efficiency in the trucking industry. Smart devices that move and adapt to driving and vehicle conditions—automatically and in real-time—have huge potential to minimize drag, save fuel, and reduce emissions.

The STEER Act was introduced in mid-2021 to accelerate the adoption of these new technologies. The proposed federal program incents trucking companies to buy and install solutions that deliver significant economic and environmental benefits.

Once the legislation is passed, vouchers will offset the upfront cost and installation. The U.S. government will cover expenditures associated with adopting fuel-efficient technologies on Class 8 trucks, among the heaviest vehicles on the road, and those with the most potential to make an impact.

“We can reduce fuel consumption and emissions in the transportation industry without enacting costly … mandates on American companies and workers,” said U.S. Representative Rodney Davis, who introduced the bill in the summer of 2021. “It’s common-sense, market-driven ideas … that will protect American workers and our environment without destroying our economy,” he said.

“The STEER Act is rocket fuel for American innovations which help the trucking industry become cleaner and more efficient.”
Daniel Burrows, Founder and CEO of TruckLabs, maker of TruckWings

CEO, Founder

Daniel Burrows agrees. The founder and CEO of TruckLabs, maker of TruckWings, an aerodynamic device that closes the gap between tractor and trailer to reduce drag, said. “One-third of the world’s carbon emissions come from the transportation sector. Fleets are spending 3% to 6% more on diesel than they should. Making it easy and affordable to consume less and reduce our carbon footprint helps us all breathe easier.”


The STEER Act authorizes $100 million annually from 2022 to 2026 to retrofit heavy-duty trucks with emission reducing technology that is currently available. Fleet size determines voucher amounts.


“This bill has huge potential to bridge the gap to zero-emission truck fleets,” Burrows said, referring to the almost 4 million Class 8 trucks in operation in the U.S. “We are proud to be part of the movement to help make the world we live in a better, more sustainable place.”

The STEER ACT was introduced to fast-track deployment of already available technologies, and make an environmental and economic impact now

One-Third of the Nation’s Carbon Emissions Come From the Transportation Sector

greenhouse gas emissions

Transportation accounts for the largest portion of total U.S. greenhouse gas emissions (GHG) released into the atmosphere.

Twenty-nine percent of carbon dioxide (CO2) emissions come from combustion of fossil fuels, including gasoline and diesel used to transport people and goods, via on-road vehicles, aircraft, trains, and ships.

One quarter of that CO2 is emitted by trucks—particularly Class 8 trucks—which are responsible for releasing high (and harmful) levels of carbon dioxide.

Increasing CO2 in the air traps heat, raises temperatures, and causes energy imbalance that negatively impacts our health and degrades the environment.

Burning fossil fuels like coal, oil, and natural gas cause most greenhouse gas emissions, which are comprised mostly of carbon dioxide (CO2). These harmful gases, generated by human activity, upset the natural greenhouse effect, and are responsible for global warming and climate change.

The evidence is alarming, but the good news is there are actions to take. Alternative energy sources, aerodynamic devices that reduce drag, and new technologies are increasingly embraced by trucking companies to reduce the industry’s effect on the world we live in.

TruckWings check every box

With 450 million over-the-road miles under its belt since 2015, TruckWings goes a long way toward doing something about GHG. As the only aerodynamic device that automatically closes the gap between cab and trailer, TruckWings is part of the solution towards reducing unhealthy emissions in the air.

Deploying at 52 mph and retracting at 50 mph—with zero driver intervention required—TruckWings gives everyone good reasons to get on board:

Drivers count on TruckWings to do their job while they stay focused on their driving. Operators know it’s there, but there’s no action required on their part to make it work.

Fleet owners depend on TruckWings for fuel savings of 4% to 6%. As advances are made toward the use of renewable energy sources like propane, natural gas, electricity, hydrogen fuel cells, and biodiesel, the same TruckWings that are installed today will deliver even more savings and sustainability benefits as new fuels become mainstream.

Those in the c-suite appreciate the fast return-on-investment TruckWings delivers. With a million-mile lifespan, the automated solution has an ROI of just 15- to 18 months.

TruckWings is making a statement. Every day, at every turn, its presence reminds drivers, customers, and those who share the road that the company responsible for the tractor-trailer that sports them is serious about running an efficient business—and making a difference for us all.
