Section 1: Comparing TRI and Greenhouse Gas Emissions

Percentage Change in Air Emissions for Facilities Reporting to Both TRI and GHGRP: 2012-2013

This figure shows the percentage change in total air emissions from 2012 to 2013 for the subset of facilities reporting to both TRI and GHGRP, in the five industry sectors with the greatest TRI air emissions. While the graph is based on a consistent subset of facilities, the percentage change in emissions by industry sector varies between the two programs. The variations are driven by differences in the types of pollutants reported to TRI and GHGRP and by the impacts of certain source reduction and pollution control activities. Some actions taken by facilities, such as reducing fuel consumption, decrease emissions of both greenhouse gases and toxic chemicals that are byproducts of fuel combustion. Other actions, like the installation of new treatment technology, may reduce emissions of a specific TRI chemical but not affect greenhouse gas emissions.
