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

Potential Benefits of 100% Clean Energy by 2050
22.8 MMT CO2e

Transportation

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

Greenhouse Gas Emissions Projections in Arizona

Created in partnership with

This chart depicts the projected greenhouse gas (GHG) emissions in Arizona by sector, measured in millions of metric tons of carbon dioxide equivalent (CO2e). Projections are derived from the Energy Policy Simulator, managed by RMI and Energy Innovation.
