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

Electricity

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

Reduction in GHGs

0.72%

Increase in GDP

19,505

Growth in Jobs

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

5.5 MMT CO2e

Status	Policy	Policy Area	Policy Category
Not Enacted	Green Banks Empty column Green banks are public, quasi-public, or non-profit entities that use innovative financing to invest in climate solutions and attract private capital across various economic sectors.	Cross-Sector	Climate Finance
Not Enacted	Carbon Pollution Pricing Empty column Carbon pollution pricing establishes a pollution fee or cap-and-trade program on the greenhouse gas emissions associated with each sector/source of emissions within the state. Programs typically cover the electricity, buildings, transportation, and/or industrial sectors.	Cross-Sector	Carbon Valuation
Not Enacted	Social Cost of Carbon Empty column The social cost of carbon is a monetary estimate of the damage of each ton of greenhouse gases emitted. The social cost of carbon is used to quantify and monetize climate damages, representing the net economic cost of climate pollution to society.	Cross-Sector	Carbon Valuation
