The graph below shows the percentage change in air emissions and greenhouse gas emissions from 2014-2015 for facilities that reported to both the Toxics Release Inventory (TRI) and the Greenhouse Gas Reporting Program (GHGRP).

From 2014 to 2015:

• For the five industry sectors with the greatest TRI-reported air emissions, this figure shows the percentage change in total air emissions for the subset of facilities reporting to both the TRI Program and the GHGRP.
• While 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 the TRI Program and the GHGRP and by the impacts of certain source reduction and pollution control activities. Actions taken by facilities may include:
  • Reduction of fuel consumption, which decreases emissions of both greenhouse gases and toxic chemicals that are byproducts of fuel combustion.
  • Installation of new treatment technology, which may reduce emissions of a specific TRI chemical but does not affect greenhouse gas emissions.
