The Obama administration announced that the US Environmental Protection Agency (EPA) and US Department of Transportation (DOT) will again be coordinating 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.
This announcement is the start of a process that will be fully fleshed-out and completed in a formal rulemaking process.
Leaders of the American Trucking Associations (ATA), while supporting the goal of improved fuel efficiency of large trucks, pressed the Obama administration to proceed cautiously with setting new standards.
