Are Climate Pledges on Life Support?
A Q&A with Catherine McKenna, who led the UN Secretary General’s High-Level Expert Group on Net-Zero Commitments of Non-State Entities.
Catherine McKenna knows firsthand how to persist in the face of pushback on climate policies. She was Canada’s Minister of Environment and Climate Change during the first Trump Administration, and she led negotiations of that country’s first national climate plan over intense oil industry opposition. “The oil sands sector and the politicians they sponsor aren’t just greenwashing a product,” …

CONTINUE READINGWhat Will 2025 Bring in Global Climate Finance?
Last year, international negotiations continued to disappoint on global climate policy, forests, and finance. This year, subnational governments must continue to lead.
As they have for many years, nations came together in 2024 at various climate-related events to push for a brighter future. From the 16th Conference of the Parties (COP) to the Convention on Biological Diversity in Cali, Colombia in October 2024, followed immediately by COP29 to the United Nations Framework Convention on Climate Change (UNFCCC) …

More than 500 Rights of Nature laws and policies have been passed globally. Here’s how to make sense of this nascent movement — or movements.
This Fall, I have been co-teaching a course on Rights of Nature with the historian Jill Lepore. This is the first time either of us have taught the subject and it has proven a wonderful opportunity to explore with our students this emerging movement — one that some have praised as “A Legal Revolution That …

Representational sovereignty, Indigenous rights, and ecocide are all key to the climate obligations of states, write guest contributors Mollie Cueva-Dabkoski, Julia Phượng Nguyễn, and Molly-Mae Whitmey.
A new chapter of global climate accountability has hopefully begun, as the International Court of Justice (ICJ) prepares to issue an advisory opinion on the Obligations of States in respect of Climate Change. Hearings for that opinion began today with over 100 countries and other parties presenting over two weeks. At the request of the U.N. General …

CONTINUE READINGOne Bright Spot to COP29 in Baku
The outcome of this year’s U.N. climate conference was depressing. But there was some notable news regarding global methane emissions commitments.
Some have described the United Nations Climate Change Conference (COP29) in Baku as “challenging,” “ineffective,” and “disappointing.” On the one hand, global greenhouse gas emissions have reached an all-time high, and the temperature for 2023 is the highest ever recorded. On the other hand, President-elect Donald Trump announced his intention to withdraw the U.S. from …

CONTINUE READINGWhat’s Making this COP Especially Difficult?
Notes from COP29 in Baku, where the subject of real money, U.S. politics, and other tricky factors are converging.
My UCLA colleagues Ted Parson, JP Escudero and I just returned from Baku. Most of our work there related to side talks on advancing methane regulation (and our UCLA project on that topic), but we also got a sense of how the central negotiations were unfolding. As the New York Times and others are reporting, …

As global leaders gather in Cali for COP16 and devastating fires continue across the Amazon, we should look to subnational groups for solutions to both the climate and biodiversity loss crisis.
The world has continued to watch as fires burn – yet again – across much of the Amazon basin. With historic droughts and ongoing lack of resources to tackle these fires and their underlying causes, they have ravaged millions of hectares of forests, communities, and wildlife habitat in Bolivia, Peru, Brazil, and beyond. These fires, …

CONTINUE READINGEarth system tipping events now seem inevitable – what does this mean for climate governance?
Building meaningful earth system governance creates multiple new research challenges
A tipping point is a system threshold beyond which change becomes self-perpetuating until a qualitatively different stable state is reached. For example a rainforest turns into a grassland, or an ice sheet melts completely. Such shifts are non-linear, and practically irreversible. Fears that growing human impacts might push aspects of the global climate past such …
CONTINUE READINGChina, Climate, and Clean Energy
China seems to have leap-frogged the U.S. on clean energy. We need to catch up.
In 2023, China accounted for about 60% of the world’s additions of solar and wind power, and of electric vehicles. The U.S. will need to make a major effort to catch up. Otherwise, we risk being shut out of important global markets and giving China an opening to influence developing countries.
CONTINUE READINGRightwing Authoritarianism vs the Environment
In the U.S. and elsewhere, rightwing authoritarians oppose climate action. That’s not a coincidence.
Project 2025 favors authoritarian presidential rule. It also wants to destroy environmental regulation, especially climate law. That’s not a coincidence. The combination of authoritarianism, extreme conservative ideology, and anti-environmentalism is common globally, not just in U.S. politics. There’s no logical connection between a belief in authoritarian government, upholding traditional hierarchies, and views about protecting the …
