EPA has issued the Final Mandatory Reporting of Greenhouse Gases Rule. The rule requires reporting of Greenhouse Gas Emissions from large sources and suppliers in the United States, and is intended to collect accurate and timely emissions data to inform future policy decisions.
The final rule for Greenhouse Gas (GHG) Emissions was signed by EPA on September 22, 2009 and became effective December 29, 2009. Under the GHG rule, suppliers of fossil fuels or industrial greenhouse gases, manufacturers of vehicles and engines, and facilities that emit 25,000 metric tons or more per year of GHG emissions are required to submit annual reports to EPA. The gases covered by the rule are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFC), perfluorocarbons (PFC), sulfur hexafluoride (SF6), and other fluorinated gases including nitrogen trifluoride (NF3) and hydrofluorinated ethers (HFE).
Example Carbon Equivalence : CH4 has a GWP of 21. Each metric ton of CH4 emissions would have 21 times as much impact on global warming as a metric ton of CO2 emissions.
Mass emissions x GWP = CO2e (metric tons)
Indirect emissions (e.g., electricity use)
