Helping States Win on Climate

In the United States, where climate change is often portrayed as a partisan issue in national politics, leaders from coast to coast are joining the movement toward clean energy at the state level. With encouragement from TNC, seven states recently adopted ambitious goals for clean energy and limiting greenhouse gas emissions. Highlights include:

New York

Electricity will come from 100% carbon-free energy sources by 2040 and achieve net zero greenhouse gas emissions by 2050.


All of the state’s electricity will come from clean energy sources by 2045.


Lawmakers approved a legal mandate of 100% zero-carbon electricity by 2045, with a renewable energy milestone of 60% by 2030.


A new successful energy bill includes a reduction of at least 90% in state greenhouse gas emissions by 2050.


Passed legislation to reduce greenhouse gas emissions by 80% and source 100% of its electricity from renewables by 2050.

Nevada & Maryland

Both committed to generate 50% of their electricity from renewable resources by 2030. Learn about Maryland's Clean Energy Jobs Act.
