How EPA is helping to reduce greenhouse gas emissions

We supply the Environmental Protection Agency with the comprehensive modeling and analysis they need to create climate change policy.


Congress, through the AIM Act, directed the Environmental Protection Agency (EPA) to address the use of highly potent greenhouse gases—hydrofluorocarbons (HFCs)—and lower their production and consumption in the U.S. by 85% over the next 15 years.


We supported the EPA in the development of guidelines for this accelerated timeline. To do so, we drew from our 30+ year history supporting the EPA on Montreal Protocol implementation and dozens of prior decisions related to the phaseout and tracking of ozone—depleting substances and the management of HFCs.


The guidelines are set. Once carried out, this global HFC phaseout is expected to eliminate up to 0.5° Celsius of global warming by 2100 and continue to protect the ozone layer.
