USEPA DEVELOPMENT AND USE OF GREENHOUSE GAS EMISSIONS INFORMATION

Abstract:

EPA uses greenhouse gas emissions data for a variety of different purposes, including the development, implementation, and assessment of mitigation policies & programs domestically and internationally. In this presentation, EPA will describe its greenhouse gas dataset requirements, how it develops and uses its own data, how it makes use of data from external providers, and some ideas for further collaboration with the research community. In particular, EPA will provide examples of the type of information and calculations used for specific sources of greenhouse gas emissions (e.g., oil & gas emissions), and how it updates its estimates for these sources on the basis of new and improved information. The presentation will also address uncertainty assessments and different types of verification approaches. The presentation will also identify key emission sources and sinks that have the highest estimated uncertainty and which could benefit from additional characterization, data collection and measurement by the research community.
