U.S. State Greenhouse Gas Emissions Targets

A greenhouse gas emissions target refers to the emission reduction levels that states set out to achieve by a specified time. Currently, 23 states and the District of Columbia have implemented statewide greenhouse gas targets. Following the United States announced withdrawal from the Paris Climate agreement, 20 states have committed to upholding the U.S. commitment of reducing emissions 26 to 28 percent below 2005 levels by 2025 by joining the United States Climate Alliance.

States use a variety of baseline years, ranging from 1990 to 2006, and a few different years for the ultimate target, ranging from 2020 to 2050. Most states have a common ultimate target year of 2050. The baseline year and additional details can be found by clicking on individual states.
