Emissions Trending and Sensitive Variable Analysis from Five Years of Mandatory Landfill Reporting under the Federal Greenhouse Gas Mandatory Reporting Regulation

摘要

Landfills are essential public services, which are not only one of the most regulated industries in the U.S. but also one of the only industry sectors which have reduced their emissions footprint way beyond 1990 levels. Many MSW landfills already have active GCCS which destroys GHG emissions under current regulations that are imposed by local air districts, states, and the federal government. The landfill industry is currently one of the few sectors under the U.S. EPA federal GHG reporting required to report fugitive emissions. Despite existing stringent regulations, the landfill industry was hit harder than any other industry under the federal MRR, with more than 1,200 landfills reporting. Only the power plants and the oil and gas sector have more reporters. The GHGRP has resulted in a significant amount of data collection by reporters and the U.S. EPA. These data have revealed some unexpected results, such as the sensitivity to parameters such as f_(Rec). Other sensitive values, such as moisture, were already well understood to have a major influence on landfill emissions.
