A greenhouse gas emissions target refers to the emission reduction levels that states set out to achieve by a specified time. For example, a state may set a target of reducing emissions to 1990 levels by 2020, and to 50 percent below 1990 levels by 2050. At present, 20 states and the District of Columbia have implemented state-wide greenhouse gas targets.

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.
