From the Document: "The U.S. Environmental Protection Agency's (EPA's) Greenhouse Gas Reporting Program (GHGRP) requires certain facilities to report their emissions of greenhouse gases (GHGs). In addition, the GHGRP requires suppliers of specific products, such as natural gas and petroleum, to report the GHG emissions that would ultimately result from the use of their products. Since 2011, the GHGRP has collected annual emissions data from nearly 8,000 large industrial facilities and other sources in the United States. According to EPA, 85%-90% of annual man-made U.S. GHG emissions have been reported under the program. [...] Congress may consider several policy issues related to GHGRP statutory authority and regulatory oversight. Congress may consider how the application and scope of GHGRP regulations align with EPA's stated goal of enhanced understanding of GHG emissions in the United States now and in the future. [...] Congress may consider whether EPA resources are adequate and being used efficiently to carry out the GHGRP under the CAA [Clean Air Act]. [...] Congress may also consider how GHGRP data might inform future legislative efforts. EPA has now collected 10 years of data on direct GHG emissions, fuel and GHG suppliers, and industry-specific emissions trends. Policymakers may consider how this information, as well as future GHGRP data, could be used in potential future legislation relating to GHG mitigation or climate change policy."
