The current administration has unveiled a new proposition on rules for heavy, long-haul trucks, with the officials calling for the curbing of greenhouse gas emissions in a move that is part of the broader climate change strategy.
The proposal, utterly complex, comes from the U.S. Environmental Protection Agency and is covering the 18-wheel tractor-trailers, buses, delivery vans, beefy heavy-duty pickup trucks and other commercial vehicles. The coming rules would make an integral part of the wider effort to lower carbon dioxide emissions across the transportation sector (along with others, such as the power one) of the economy. They are also coming close to the upcoming new round of discussions on global climate change, scheduled in Paris this year. The regulator is expected to finish drafting the new rules beginning with next year and the public, including industry and environmental groups, will have 60 days to comment the proposal.
Immediately after power plant emissions, transportation is the second largest source of greenhouse gasses, making up around 27 percent of the total. The new rules are designed to curb the emissions by 1.1 billion tons (1 billion metric tons), lower fuel consumption by 1.8 billion barrels of oil and decrease fuel costs by $170 billion between 2018 and 2027. The new standards have proposed a 24 percent average fuel consumption reduction for truck tractors by 2027 from expected 2018 thresholds. The new rules also come up with an 8 percent improvement sourced from new aerodynamic truck trailer designs. According to the EPA, the targets will be differently set across the vastly different classes of heavy trucks, taking into account the many types of work commercial vehicles are implicated in.
