Newsweek: From California to the Amazon—Local Leaders Are Changing the Climate Game | Opinion

November 6, 2025
California Governor Gavin Newsom joins with Governor Helder Barbalho of Pará, Brazil to spotlight how state and local leaders are making progress when national politics stall on climate issues.

“Equally important is collaboration across states. Coalitions in the United States, like the U.S. Climate Alliance and America Is All In, bring governors together with mayors and business leaders in the effort to expand clean energy and resilience. Similarly, the Interstate Consortium for the Sustainable Development of the Legal Amazon Region brings together Amazonian states to curb deforestation, promote green agriculture and attract green investment.

 

Already, we have seen remarkable momentum; between 2005 and 2023, states in the U.S. Climate Alliance slashed greenhouse gas emissions by 24 percent, while increasing GDP by 34 percent. The Consortium, meanwhile, has mobilized hundreds of millions of dollars toward sustainable development in the Amazon.”

About the Alliance

Launched in 2017 by the governors of Washington, New York, and California to help fill the void left by the U.S. federal government’s withdrawal from the Paris Agreement, the Alliance has grown to include 24 governors from across the U.S. representing approximately 60 percent of the U.S. economy and 55 percent of the U.S. population. Governors in the Alliance have pledged to collectively reduce net greenhouse gas emissions by at least 26-28 percent by 2025, 50-52 percent by 2030, and 61-66 percent by 2035, all below 2005 levels, and collectively achieve overall net-zero greenhouse gas emissions as soon as practicable, and no later than 2050.  

 

The Alliance’s states and territories continue to advance innovative and impactful climate solutions to grow the economy, create jobs, and protect public health, and have a long record of action and results. In fact, the latest data shows that as of 2023, the Alliance has reduced its collective net greenhouse gas emissions by 24 percent below 2005 levels, while increasing collective GDP by 34 percent, and is on track to meet its near-term climate goal of reducing collective greenhouse gas emissions 26 percent below 2005 levels by 2025.
