Planning Begins For Next Phase Of Heavy-Duty GHG Regs
The Obama Administration has announced that the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Transportation (DOT) will again coordinate their efforts to implement a uniform, second phase national program to reduce greenhouse gas (GHG) emissions and improve fuel efficiency from medium and heavy-duty trucks and buses. The announcement is the start of the formal rulemaking process.
The Truck and Engine Manufacturers Association (EMA), the trade association representing worldwide manufacturers of medium and heavy-duty trucks and internal combustion engines, supported the move.
“As the primary manufacturers of medium and heavy-duty engines and vehicles in the United States, EMA’s members want to ensure a uniform, national program to address greenhouse gas emissions and fuel efficiency,” said Jed Mandel, EMA president. “The industry is still in the process of implementing the first EPA/NHTSA greenhouse gas/fuel efficiency program which only went into effect last month.
“Nevertheless, EMA and its members are committed to working with EPA and NHTSA to assure that a second phase program recognizes the commercial needs of the marketplace; balances stringency and cost while providing adequate leadtime and stability; avoids unintended consequences; and assures uniform, accurate and cost-effective assessment/measurement methods.”
EMA said truck and engine manufacturers expect that any future program should evaluate tractor efficiency (when coupled with a high-efficiency trailer) and consider opportunities for advanced trailer designs and overall road freight efficiency improvement.
