ASTM International says it is a primary standards contributor to a recent rule approved by the U.S. Environmental Protection Agency on greenhouse gas reporting by large sources and suppliers in the United States.The final Mandatory Reporting of Greenhouse Gases Rule was enacted in response to the Consolidated Appropriations Act of 2008 (H.R. 2764; Public Law 110-161). Under the rule, manufacturers of vehicles and engines and other entities that emit 25,000 metric tons or more per year of greenhouse gas emissions are required to submit annual reports to EPA.

The rule goes into effect on January 1, 2010. First annual reports are to be submitted to the EPA in 2011, covering calendar year 2010.

Gases covered by the rule are: carbon dioxide; methane; nitrous oxide; hydrofluorocarbons; petrofluorcarbons; sulfur hexafluoride; and other fluorinated gases, including nitrogen trifluoride and hydrofluorinated ethers.

The purpose of the EPA’s new reporting system is to provide better understanding of the sources of greenhouse gases, which are produced by burning fossil fuels and through industrial and biological processes. Report data may also identify cost-effective ways to reduce future greenhouse gas emissions, according to ASTM.
