This figure shows the top sectors reporting air emissions to the Greenhouse Gas Reporting Program (GHGRP) and the Toxics Release Inventory (TRI) in 2015.

In 2015:

• The top air emitting sectors in TRI are similar, but not identical to, the top emitting sectors covered by the GHGRP.
• While electric utilities are a primary source of air emissions reported to both programs, both the chemical manufacturing and paper sectors report more toxic chemical air emissions than are reported by electric utilities. In prior years, electric utilities were the largest contributor to TRI air emissions, but with shifts in the sector toward natural gas and renewable energy sources, as well as improved emission controls, the sector is no longer the largest contributor to TRI air emissions.
