EPA develops an annual report called the Inventory of U.S. Greenhouse Gas Emissions and Sinks (Inventory). This report tracks total annual U.S. emissions and removals by source, economic sector, and greenhouse gas going back to 1990. One sector in the annual report is the waste sector, which includes municipal solid waste (MSW) landfills, industrial landfills, composting, and wastewater. With each Inventory report, EPA strives to improve the data inputs and calculations used.
On December 8th, 2016, EPA held a stakeholder webinar on the Inventory data and methodology for the waste sector, with a focus on MSW landfills. During the webinar, we presented information on how the Inventory for MSW landfills is developed, the methodologies and calculations that are used to produce final emissions values, and the data sources currently being used as inputs to these calculations. The webinar also covered efforts to incorporate the Greenhouse Gas Reporting Program (GHGRP) data into the Inventory and noted specific areas where we would like stakeholder input.
Please send any input on use of the GHGRP data in the Inventory to schmeltz.rachel@epa.gov and kbronstein@rti.org.
