Natural Gas and Petroleum Systems

2011 Cover Graphic

It is EPA's standard process to update the Inventory of US. Greenhouse Gas Emissions and Sinks (GHG Inventory) when relevant new and improved data are available. In recent years, as improved data have become available, EPA has updated methods and data sources for calculating greenhouse gas emissions for several key sources in the natural gas and petroleum sectors. See below for materials regarding EPA estimates of greenhouse gas emissions from natural gas and petroleum systems.
