Despite Biden Push for Green Transportation, U.S. Trucking Still Drives on Diesel

“Getting to net-zero carbon emissions by 2050 means we must aggressively cut down the largest source of emissions: the transportation sector,” said President Joe Biden’s Secretary of Energy Jennifer Granholm in April 2021. It was part of the administration’s aggressive push to reduce the use of fossil fuels and switch Americans to technologies like electric vehicles (EVs).

But a new report shows how far away the transportation sector is from that goal.

An analysis by Diesel Technology Forum (DTF) finds while emerging fuels and technologies are coming into play, more than three-quarters of America’s commercial trucks are powered by diesel.

“It was a really comprehensive look,” says Allen Schaeffer, DTF Executive Director. “We looked at different states and different powertrains, which states have added the most vehicles, and new generation diesels, which were lagging in terms of the turnover of their fleets.”

The findings:

  • 76 percent of the approximately 15 million commercial trucks (Class 3-8) that make up the nation’s fleet run on diesel power;
  • 79 percent of all non-school (transit) buses in operation are powered by diesel, with another 10 percent compressed natural gas; (CNG);
  • 91 percent of the approximately 500,000 school buses run on diesel as well.

As for electric vehicles, they make up less than one percent of the commercial truck or school bus fleets. About six percent of transit buses are electric, the report found.

“It was a really comprehensive look,” says Allen Schaeffer, DTF Executive Director. “We looked at different states and different powertrains, which states have added the most vehicles, and new generation diesels, which were lagging in terms of the turnover of their fleets.”

Schaeffer says there is a commitment by truck and engine manufacturers to move toward zero-emission vehicles. Companies like Volvo, Isuzu, Cummins, and General Motors all have advanced options that include diesel as well as electric trucks.

“So, it is coming in some form, but the question is ‘how fast will that kind of transition take place?’” says Schaeffer.

The slow progress is not due to a lack of government effort. Seven major manufacturers have pledged to phase out diesel engines in Europe by 2040. At least 15 states in the U.S. are imposing quotas on sales to boost EVs in the marketplace. California wants 100 percent zero-emission passenger cars and light truck sales by 2035.

But with EVs making up about 3 percent of the cars on the road nationwide, there is a long way to go to achieve the Biden administration’s goals.

As for the push to replace “dirty” fossil fuel-powered vehicles with clean energy ones, Schaeffer says there is the option of vehicles using biodiesel and renewable diesel.

“Renewable diesel is playing a growing role in both the public and private fleets, primarily in California but also the Pacific Northwest as well,” said Schaeffer. “In the case of renewable diesel fuel, they can be used in any diesel vehicle, (so) it doesn’t have to be a new one, (and) there is no requirement for new fueling infrastructure.”

According to Schaeffer, operators using that type of fuel today could reduce their greenhouse gas emissions anywhere from 50 percent to 86 percent depending on the source of their feedstocks. Schaeffer noted using biodiesel and renewable diesel could help bring down the high cost of petroleum diesel.

“They can be blended in with petroleum diesel at any quantity,” said Schaeffer of biodiesel and renewable diesel fuel. “The future might be a lot more electric; we will have to see about that, but of course, there are many challenges there, not just with the vehicles and the charging infrastructure, but how clean is the power?”

According to the U.S. Energy Information Administration, about 61 percent of the electricity generated in the U.S. in 2021 was from fossil fuels—coal, natural gas, petroleum, and other gases. Another 19 percent was from nuclear power. Total renewables, including hydropower, wind, and solar, generated just 20 percent.

“We have not reached a point in time where renewables like solar and wind and hydro are the dominate sources,” Schaeffer said. “Some states are further down that road than others, but it’s important to understand all the twists and turns here and that’s why we wanted to do this analysis, was to say, ‘what is on the road today, what is getting the job done, and which states have higher populations of advanced vehicles?’”

And then there are the price impacts. Trucks deliver about 70 percent of all goods transported across the country, and higher costs for shipping translate to higher costs of food and other necessities. That is a tough sell when inflation is hitting numbers not seen since 1981.

Alix Miller, the president and CEO of Florida’s Trucking Association, told reporters that while consumers don’t pay higher shipping costs upfront, they see the impact on store shelves.

“Everything we bring, eat, touch, wear, drive on is brought to you by a truck, and when prices increase…it makes it incredibly difficult to continue to do business and deliver freight,” Miller said.

DelVal Shoppers Face Empty Shelves as Supply Chain Woes Continue

Delaware Valley consumers are encountering empty shelves and a shortage of products, a situation that is frustrating retailers and customers alike.

“That store is remodeling for Build Back Better,” joked Anita Edgarian of West Chester on Facebook. “When are we going to get our ration books? We’re not even in a war and the shelves are empty.”

She is not alone. A poll of swing-state voters found about 7 in 10 respondents have experienced shortages at grocery stores.

The question is why?

Giant Food Stores LLC, based in Carlisle, Pa. operates 190 stores in Pennsylvania, Maryland, Virginia, and West Virginia. On visits to two Eastern Montgomery County Giant locations in recent weeks, some shelves were sparse while others were entirely bare.

Ashley Flower is Giant’s manager of public relations.

“Our supplier and manufacturing partners have advised us of supply, production, and or sourcing challenges they are facing,” she said, “which impacts what is available in our stores (and others) for purchase. Historic demand and a stretched supply chain have contributed to limited product availability in certain cases.

“Many other factors like ongoing labor shortages, limited availability of raw ingredients, freight and packaging constraints, and unpredictable weather events are beyond our control. It’s a fluid situation and one we are monitoring closely. We continue to remain in close contact with our suppliers and are working to bring in alternate products, but it is possible customers may find a particular brand or variety is unavailable due to these challenges,” she said.

The National Grocers Association (NGA) serves more than 1,500 retail and wholesale grocers nationwide.

“Product availability and price inflation are being driven by a perfect storm of factors,” said NGA director of communications Jim Dudlicek, “That includes an ongoing shortage of labor across the entire supply chain, an acute shortage of truck drivers, increased ingredient inputs, and occasional disruptions in product packaging production. Weather emergencies also have been a factor in some parts of the country.”

A sizable percentage of products, including grocery items, are shipped by truck. According to the American Trucking Association, trucks moved 10.23 billion tons of freight in 2020, generating $ 732.3 billion in revenue. That accounts for better than 72 percent of tonnage carried by all modes of domestic freight transportation, including manufactured and retail goods.

But the trucking industry was dealing with its own issues well before the pandemic, specifically, a shortage of drivers. And that shortage was exacerbated by the Biden administration’s mandate that employees of large companies (100 workers or more) be vaccinated or else wear masks and be regularly tested for COVID.

That mandate was recently struck down by the U.S. Supreme Court. However, Dudlicek believes the supply chain issues will remain, at least for the short term.

“While there is plenty of food in the supply chain, we anticipate consumers will continue to experience sporadic disruptions in certain product categories as we have seen over the past year and a half due to the ongoing supply and labor challenges,” he said.

“The prevalence of the omicron variant in both vaccinated and unvaccinated populations, coupled with the lack of available testing resources, has further contributed to current staffing challenges. While our members continue to encourage employees to get vaccinated, NGA has requested prioritization of testing supplies from both federal and state government, alongside flexibility from onerous mandates so that our ‘Supermarket Superheroes’ can continue to work and communities across the country are not impacted by significant workforce disruptions,” he said.

However, another wrinkle in the trucking situation is vaccine requirements for truckers who cross the border into Canada or drive from Canada into the U.S., which may also generate shortages issues in the near future.
