EPA Introduces Stricter Emissions Standards on Trucks

The EPA has long been focused on methods of decreasing carbon dioxide emissions, one of the main focuses being combustion engines. The EPA says the transportation sector currently makes up 29 percent of carbon emissions. Further stressing the urgent importance of cutting carbon emissions due to negative effects on people’s health. 

There have been multiple times in the past where the EPA has tightened the restrictions on carbon emissions, forcing new vehicles to lower their output. The last time we saw a change, the EPA had implemented phase 2 of their plan in 2016. 

On March 29, the EPA took the next step in this process, increasing restrictions on heavy duty vehicles, such as delivery trucks, refuse haulers, public utility trucks, transit, shuttle, school buses, etc., and tractors (such as day cabs and sleeper cabs on tractor-trailer trucks). These new restrictions will be required on vehicles that are model year 2027 and later. Their target for this plan is lofty, and varies by vehicle, ranging from 25 percent reduction on sleeper cab tractors to 60 percent reduction on light-heavy vocational vehicles by 2032. 

There are differing perspectives about this change. The EPA has advertised that this change will produce $13 billion in annualized net benefits through the year 2055, speculating $10 billion of climate benefits and saving in health effects. However, University of Nebraska has analyzed that these types of shifts cause a decrease in biofuel consumption, and have the potential to cripple the agricultural industry, and thereby the economy. While the EPA has high hopes for this plan, Nebraska Farm Bureau believes they should take a step back, and thoroughly analyze all the economic consequences it could cause.
