Greenhouse Gas Emissions Standards Phase 3: A Step Toward a Cleaner Future

The Environmental Protection Agency (EPA) recently proposed new greenhouse gas (GHG) emissions standards for heavy-duty vehicles known as phase 3. The proposed standards, which would apply to heavy-duty truck OEMs for upcoming model years 2028-2032, are the most stringent ever set by the EPA.

Phase 1 and 2 of the Greenhouse Gas Emissions Standards for Medium- and Heavy-Duty Vehicles were implemented in 2014 and 2017, respectively. The standards reduced greenhouse gas (GHG) emissions from medium- and heavy-duty vehicles by 11% and 14%, respectively, below 2010 levels by 2021. 

If finalized, the new Phase 3 standards would reduce GHG emissions from heavy-duty vehicles by 29% below 2021 levels by 2032. This would help mitigate climate change’s effects and improve air quality.

The proposed standards would apply to a wide range of heavy-duty vehicles, including trucks, buses, and trailers. They would be phased in over time, with the most stringent requirements applying to model year 2032 vehicles.

The EPA estimates that the new standards would cost the heavy-duty vehicle industry an average of $1,700 per vehicle. However, the agency also estimates that it would save the industry $1.5 billion in fuel costs over the life of the vehicles.

Key Differences in Phase 2 and Phase 3 of the Greenhouse Gas Emissions Standards

  • Stringency: Phase 3 standards are significantly more stringent than Phase 2 standards. Phase 3 standards would reduce GHG emissions from heavy-duty vehicles by 29% below 2021 levels by 2032. Phase 2 standards reduced emissions by 17% below 2010 levels by 2021.
  • Applicability: Phase 3 standards would apply to a wider range of vehicles than Phase 2 standards. Phase 3 standards would apply to all heavy-duty vehicles, including trucks, buses, and trailers. Phase 2 standards applied to all heavy-duty vehicles except for school buses.
  • Timeline: Phase 3 standards would be phased in over a more extended period of time than Phase 2 standards. Phase 3 standards would apply to model years 2028-2032. Phase 2 standards applied to model years 2021-2027.
  • Technology: Phase 3 standards would rely on a wider range of technologies than Phase 2 standards. Phase 3 standards would allow for the use of various technologies, including advanced diesel engines, hybrid electric vehicles, and battery electric vehicles. Phase 2 standards primarily relied on the use of advanced diesel engines.
  • Cost: Phase 3 standards are estimated to be more costly than Phase 2 standards. The EPA estimates that the Phase 3 standards would cost the heavy-duty vehicle industry an average of $1,700 per vehicle. However, the agency also estimates that the standards would save the industry $1.5 billion in fuel costs over the life of the vehicles.

22021 – 202717% below 2010 levels
32028 – 203229% below 2021 levels

Special Provisions for Aerodynamic Technologies

The EPA’s proposed rule for Phase 3 also includes several provisions that would encourage using aerodynamic technologies to reduce drag and improve fuel efficiency. These provisions include:

Drag Coefficient Requirements for Phase 3
TruckTrailer
Model Year 20280.550.62
Model Year 20320.500.60
  • Requiring manufacturers to meet minimum aerodynamic requirements for new vehicles.
  • Providing credits to manufacturers for meeting more stringent aerodynamic requirements.
  • Investing in research and development of new aerodynamic technologies.

The EPA estimates that these requirements will reduce drag by an average of 10% for trucks and trailers, leading to an average improvement in fuel efficiency of 2%. 

The EPA estimates these requirements could reduce GHG emissions by an additional 1% below the standards’ baseline. This would bring the total potential reduction in GHG emissions from phase 3 to 30% below 2021 levels by 2032.

Industry Feedback

The new standards have been met with mixed reactions from the heavy-duty vehicle industry. Some industry groups have praised the standards, saying they are necessary to address climate change. Others have criticized the standards, saying they are too costly and will harm the industry.

The American Trucking Association (ATA), the largest trucking trade group in the United States, has said that it supports the goals of the Phase 3 standards but is concerned about the cost of meeting them. The ATA has said that the standards could cost the trucking industry $15 billion to $20 billion over the next decade.

The EPA has said it is working with the trucking industry to help them meet the Phase 3 standards. It provides technical assistance to the industry and works to ensure that the standards are flexible enough to allow the industry to innovate and find new ways to reduce emissions.

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.

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

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.

Driving forward with an ESG strategy can not only place your company in a better light with investors, partners, and customers, but also deliver significant cost savings. Fuel efficiency solutions lower costs and can even improve driver comfort.

As climate change measures increase globally and the carbon footprint of the transportation industry draws greater scrutiny, the promise of change can be a benefit for all.
