Climate Change in the Pacific Southwest
— State Activities

Lake Mead
Drought causes low water in Lake Mead (Nevada, Arizona)

States are taking significant action to curb greenhouse gases. In Region 9, California is leading a coalition of states in efforts to address climate change. EPA is working closely with all of our state partners to provide funding and to help assess and reduce greenhouse gas emissions. This page provides information on current emissions inventories and state climate change activities.

The emissions from this region account for approximately 10% of U.S. greenhouse gas emissions, with California accounting for the vast majority of those emissions due to the high population in this state. Region 9 states have lower per capita emissions than the national average, in part reflecting the warmer climate and decreased need for heating in the winter. California and Arizona also produce less carbon intensive energy than the nation as a whole, partially due to the use of hydropower and nuclear in these states.

Decoupled Utilities: Utilities receive profits for cutting energy consumption rather than increasing it      
Net metering: Distributed renewables tie into the grid, providing cost benefits to renewables producing at peak times
Feed-in-Tariffs: Utilities or end-users fund renewable electricity by paying for production at above-market rates
