California Moves to Fill the Void Left by the Federal Government on the World Stage

This week, people from around the world descended on Belém, Brazil, a gateway to the Amazon rainforest. They’re there for the United Nations’ annual climate summit, called COP30, so-named for the 30 years the meeting has been in existence.

But missing among them will be delegates from the federal government of the U.S., including President Trump, who has denied the existence of climate change. The lack of federal officials does not mean the country won’t be represented, however. Filling the void are leaders from states and cities alike. And California is leading the pack.

“California is a stable and reliable partner in low-carbon green growth,” Gov. Gavin Newsom said while attending the gathering along with several of his top climate leaders. “I’m here because I don’t want the United States of America to be a footnote at this conference.”

“It’s embarrassing that the federal government is missing in action on this global crisis,” said Wade Crowfoot, California’s Natural Resources Secretary, who’s in Brazil alongside Newsom this week and spoke with KQED.

While the formal part of the conference involves delegates hammering out goals around reducing emissions and more, California has been working through other channels, from both informal meetings to signing memorandums of understanding with other countries, states, and cities.

“The fact is that states and cities, led by California, are working to fill the void,” Crowfoot said.

California has long punched above its weight in shaping U.S. environmental rules. In the late 1950s, the state established clean air standards before the federal Clean Air Act, signed by President Richard Nixon in 1970.

Over time, the state has partnered with other countries like China and Australia on goals like improving air quality. Crowfoot said these agreements are both symbolic and substantive.

“In each instance, the policy and program staff of the different jurisdictions spends months, sometimes a couple of years, really identifying capacities or technologies or expertise that that one government has that the other government might be interested in,” Crowfoot said.

California partnered with Brazil in September to help it set up a carbon market. Another recent deal will bring Danish flood management expertise to California’s delta region.

Experts said agreements like these aren’t new, but they are more visible given the vacuum of federal climate leadership.

Newsom is not the only U.S. governor attending the conference or meetings happening around the formal event. Governors Michelle Lujan Grisham of New Mexico and Tony Evers of Wisconsin also traveled to the climate event.

“The impact of governors and mayors traveling to Brazil is to make sure that the rest of the global community recognizes how much progress the United States is still making in spite of the headwinds,” said Casey Katims, executive director of the U.S. Climate Alliance, a coalition of American governors committed to keeping emissions low.

Chris Field, director of Stanford’s Woods Institute for the Environment, said the federal government is forfeiting leadership and future economic opportunities by not attending or taking action on climate. But, he said, non-nation actors do matter.

“There are critically important roles for states and companies and communities and even individuals. The whole thing is going to be successful only if we can figure out a way to get everybody moving in the same direction,” he said.

California’s consistency, despite which political party has held the governor’s office, has been very important in moving the climate needle, Field said.

Gov. Newsom has already signed even more agreements while in Brazil. One is with Colombia, to address, among other things, the potent greenhouse gas methane. And another is with Nigeria, to help increase the adoption of electric vehicles.

The state’s representation at COP comes as President Trump has rolled back national climate policies. And, for the second time, the U.S. began the process of removing itself from the Paris agreement, which aims to limit global warming.
