Growing body of research reveals high stakes for California leaders to get the details right in Senate Bill 540

By Michael Colvin / Published: August 21, 2025

This blog was supported by Julia Young, an Andlinger fellow from Princeton University. This is the third in a blog series on the opportunities presented by the Pathways Initiative, focused on California.  

California’s legislature is winding down to the last days of its session. A top priority should be finding ways to save families money on their utility bills without compromising the state’s clean electricity goals. A well-designed western electricity market does just that, according to a new analysis supported by EDF.

The difference between lawmakers getting the details right or wrong in Senate Bill 540 is significant.  Getting it wrong jeopardizes the future of a unified western electricity market, costing Californians $350 million dollars a year. This affirms prior research about the need to get the details right since that would enable Californians to save more than a billion dollars each year in energy costs by developing a unified western market.

How the Trump administration is obstructing clean energy – and why it raises your costs

By Ted Kelly / Published: July 31, 2025

A black and white photograph of solar and wind projects is being torn in half to reveal a coal plant overlaid with an upward trend line to reflect rising costs.

Last updated August 20, 2025.

Electricity prices are rising across the U.S. Demand for electricity is going up for the first time in 20 years. And more extreme weather and heat waves are causing blackouts.

Yet instead of expanding access to low-cost, reliable clean power, the Trump administration is making the problem worse. Since Day One, the administration and its allies in Congress have pushed policies that restrict the supply of affordable, homegrown clean energy – creating a self-inflicted rate hike just as the country needs more power.

Wind and solar offer some of the cheapest – and fastest – ways to provide electric power today. In contrast, the cost to build natural gas plants is at a 10-year high and a shortage of turbines is delaying construction, while coal remains the most expensive and dirtiest way to generate power. To put it simply: Blocking cheap, clean energy while doubling down on outdated fossil fuels makes no economic or environmental sense.

The attacks on clean energy will not only hike up our electricity bills, but they will also unleash more pollution in our water and air, kill thousands of jobs and make our electric grid weaker.

How is this happening? Here are major ways the Trump administration is obstructing clean energy: Read More »

The Science Is Clear on the Dangers of Planet-Heating Pollution

By Lisa Dilling / Published: July 11, 2025

This post was co-authored by EDF Climate Scientist Fiona Lo and was updated on Aug. 7, 2025.

The Trump EPA is trying to reverse the Endangerment Finding – the science-based determination that climate pollution harms public health and welfare. That’s in spite of mountains of scientific evidence confirming that climate pollution is driving extreme weather events and putting people at risk.

The scientific evidence was clear that climate pollution endangers public health and welfare when EPA issued the Endangerment Finding in 2009 – but it is even clearer now:

Jalisco’s Path to High-Integrity Jurisdictional Climate Finance: A Model for Climate Action and Territorial Justice

This post was authored by Edgar Godoy, Associate Vice President for Jurisdictional Alliances, and Paola Bauche, Secretary of Environment and Territorial Development, State of Jalisco, Mexico.

As the urgency of the climate crisis intensifies, jurisdictional REDD+ approaches have emerged as a scalable, equitable, and results-based solution for tackling deforestation and forest degradation. In Mexico, the State of Jalisco stands out as a subnational leader, having developed and begun implementing a jurisdictional REDD+ model rooted in long-term vision, institutional strength, and a strong commitment to forest communities’ rights. In its role as strategic partner to the Government of Jalisco, Environmental Defense Fund has been providing targeted technical assistance, supporting the development of emissions baselines and safeguard frameworks, and bolstering Jalisco’s alignment with international best practices in high-integrity carbon markets.

With over 4 million hectares of forest cover, representing more than 50% of its territory, Jalisco’s forests are critical for biodiversity conservation, climate regulation, and the livelihoods of hundreds of communal land communities, called ejidos, and Indigenous communities. The state’s REDD+ Strategy, developed through inclusive, participatory processes, links forest conservation, restoration, land-use planning, and sustainable rural development. It aligns with Mexico’s national REDD+ framework and the country’s commitments under the Paris Agreement.

Bonn 2025: Charting the Path to COP30 and Enhanced Climate Action

By Sarah Swain and Zach Cohen / Published: June 12, 2025

2025 June Climate Meetings. UNFCCC/ Amira Grotendiek

Next week, the international climate community will convene in Bonn for the 62nd session of the UNFCCC Subsidiary Bodies (June 16-26, 2025), or SB62. SB62 marks a critical milestone on the road to COP30 in Belém, Brazil, shaping the preparation and setting the stage for the negotiations.  

The meetings in Bonn will be guided by a central principle set by COP30 Presidency: the idea of “global mutirão,” the power of collective action to achieve goals no single actor can accomplish alone. Brazil has launched this initiative to identify common ground across regions and sectors, finding areas of convergence that can drive ambitious climate action forward. The Presidency has underscored the urgent need for this collaborative approach, particularly at SB62, to rebuild the multilateral trust strained during COP29 and by widening geopolitical rifts.  

Answering the global call for climate action, the Environmental Defense Fund (EDF) is putting the spirit of “mutirão” into practice. At its core, EDF’s “mutirão” is already in our DNA. We play a unique role working with partners and allies across society – from local communities, major companies, Indigenous Peoples, governments and more – to find the shared goals that lead to groundbreaking solutions. Embracing collaboration and partnership has led us to impactful wins for planet and people: from supporting Indigenous Peoples’ participation in UN spaces to conserve forests, to gathering national oil companies together under an ambitious goal to slash methane emissions. Our commitment to this inclusive approach is essential for rebuilding the global trust needed for swift, fair, and ambitious climate action that delivers.  

Here are the thematic issues and topics EDF will be actively engaged in during SB62:

Cap-and-invest program continues to drive down climate pollution and raise investments in Washington state

By Caroline Jones / Published: June 11, 2025

Results were released today for Washington’s second cap-and-invest auction of the year, administered last Wednesday by the Department of Ecology (Ecology). During the auction, participating entities submitted their bids for allowances. Under the Climate Commitment Act — Washington’s landmark climate law that sets a binding, declining limit on pollution — major emitters in Washington are required to hold one allowance for every ton of greenhouse gas they emit, with the total number of allowances decreasing each year. This system requires Washington’s polluters to reduce their emissions in line with the state’s climate targets, as fewer allowances become available annually.
