California and Brazil are expanding their partnership to cooperate on climate, clean energy, cutting pollution, and job-creating climate opportunities. California and Brazil signed a memorandum of understanding (MOU) on the sidelines of a United Nations meeting, establishing a framework for information sharing and collaboration on climate policy.
California has pursued subnational agreements as part of its climate policy. Earlier in 2025, Governor Gavin Newsom signed an MOU on environmental protections with a Brazilian consortium of 21 states. The recent agreement, according to the governor’s office, builds on this earlier MOU. The areas of cooperation include:
Development and implementation of market-based carbon pricing programs;
Advancement of clean transportation through the adoption of low-carbon fuels, expansion of zero-emission vehicles (ZEV) and infrastructure, enhanced public transit systems;
Advancement of clean energy, including battery technology, transmission planning, and renewable energy;
Nature-based solutions, including the forest health, the conservation of 30% of lands and oceans by 2030, and land management;
Cultural heritage;
Sustainable urban planning;
Climate change resilience;
Circular economy and waste management;
Air quality management, including monitoring.
“By strengthening our partnership with Brazil, California is reaffirming a simple truth: global challenges require global cooperation,” Newsom said in a press release.
