About 10,000 of the nation's largest greenhouse gas emitters will be required to report the specific data under the new rules.
Dena Krueger heads the EPA's Climate Change Division.
"This kind of information about their level of emissions and how they're changing over time should be very important for them because it's difficult to manage what you're not actuallyÎ¾measuring. From where we sit at the Environmental Protection Agency we are looking at how to deal with greenhouse gases,Î¾the policies and programs that we could implement to reduce emissions and this type of data is very important to us as we look into the Clean Air Act to see how we can cost effectively reduce emissions and protect the environment."Î¾Î¾Î¾
Greenhouse gases include carbon dioxide, methane and nitrous oxide, among many others, and are produced in part by industrial activities. The data collection will begin in January and be required only for facilities that emit 25,000 metric tons of CO2 equivalent every year.
"Only the largest facilities in the country, the really big factories and power plants, as well as the suppliers of fossil fuels, will be reporting under the rule. We used the threshold because we did not want to impose a reporting burden on small businesses or on housesÎ¾or cars or things like that."Î¾Î¾
Krueger says the largest facilities account for about 85-percent of the nation's total greenhouse gas emissions.
