Southwest

Arizona

Arizona has abundant non-fossil fuel energy resources, ranking 5th among states for solar-powered generation. The state is home to one of the largest nuclear power plants — and third largest power plant of any kind — in the country, although fossil fuels still comprise around half of in-state electricity generation. Net emissions increased 21% from 1990-2021, with only the electricity generation and waste and materials management sectors decreasing emissions. More than a quarter of Arizona’s land is held by tribes — the largest share in any state — and almost all of the state’s energy mineral resources are on tribal lands.

Greenhouse Gas Emissions Reduction Targets

Greenhouse gas (GHG) emissions reduction targets are set by a state to reduce the amount of GHG emissions across all economic sectors. These targets aim to limit emissions by certain amounts over time, often expressed as a percentage reduction from a baseline year.

GHG Targets
50% reduction
By 2030
Net-zero emissions
By 2050

Clean Energy and Renewable Portfolio Standards

15% renewable energy by 2025, on an annual load basis

Zero-Emission Vehicle (ZEV) Mandates

Zero-Emission Vehicle (ZEV) mandates, also known as "clean car standards," require automakers to produce and sell a certain percentage of zero-emission light-duty vehicles each model year based on total new vehicle sales. The most stringent ZEV mandates require 100% of new vehicle sales to be electric by 2035 and are known as "Advanced Clean Cars II".

Potential Benefits by 2050
