California and Brazilian officials bolstered their joint climate policies Tuesday with a new partnership covering emissions markets, forest health and low-carbon transportation.

What happened: Gov. Gavin Newsom and Brazilian officials met Tuesday while in New York City for a week of climate-related events pegged to the United Nations General Assembly.

As part of the meeting, Marina Silva, Brazil’s minister of the environment and climate change, and Yana Garcia, California’s secretary for environmental protection, signed a new memorandum of understanding detailing areas for voluntary information sharing and joint policymaking, including the creation of high-quality carbon offsets and carbon-neutral biofuels that don’t further worsen deforestation.
