A new ruling handed down by the U.S. Environmental Protection Agency will require fossil fuel and industrial suppliers, motor vehicle and engine manufacturers, and facilities that emit 25,000 metric tons or more of carbon dioxide equivalent per year. Heavy-duty truck and engine manufacturers will be required to start reporting carbon dioxide emissions in 2011 and methane emissions in 2012. In 2013, manufucturers using NOx aftertreatment technology must report nitrous oxide emissions.

WASHINGTON — The Environmental Protection Agency has issued a final rule requiring large emitters of greenhouse gas emissions, including manufacturers heavy-duty trucks and engines, to report emissions data annually.

However, thanks to lobbying efforts by the trucking industry, for-hire trucking companies will not be required to report their GHG emissions output.

Mandated reporting of carbon dioxide emissions for heavy-duty truck and engine makers will begin with model year 2011 equipment.

The following year, manufacturers will report methane emissions as well. Manufacturers must report nitrous oxide emissions in 2013, but this only applies to those that use NOx aftertreatment technology.

The initiative is part of a larger reporting requirement that applies to about 85 percent of the nation’s greenhouse gas emissions. It will cover fossil fuel and industrial suppliers, motor vehicle and engine manufacturers, and facilities that emit 25,000 metric tons or more of carbon dioxide equivalent per year.

The new rule does not apply to manufacturers in the light-duty segment, or to those manufacturers that meet the EPA’s definitions of “small business” or “small volume manufacturer.”
