Are America’s New Emissions Targets Strong Enough?

On Biden’s big announcement, Montana’s climate case, and the murder hornet

Are America’s New Emissions Targets Strong Enough?

Current conditions: Temperatures across western states are between 10 and 20 degrees Fahrenheit above seasonal averages • A temple in Thailand collapsed after unrelenting heavy rain • It’s hot and humid on the remote Caribbean island of Sombrero, where a lizard that was facing extinction six years ago has made a remarkable comeback thanks to conservation efforts.

THE TOP FIVE

1. Biden unveils tougher emissions targets in new NDC

In one of his last major environmental moves before leaving office, President Biden today announced a new climate plan for the United States that includes tougher emissions targets.

  • The old goal: Reduce all emissions by 50% to 52% (compared to 2005 levels) by 2030.
  • The new goals: Cut all emissions across the economy by 61% to 66% by 2035, curb methane specifically by at least 35%, and become net zero by 2050.

All countries under the Paris Agreement are required to submit updated climate plans – or nationally determined contributions (NDC) – by February of next year. While the new goal is an improvement, it is “at the lower bound of what the science demands and yet it is close to the upper bound of what is realistic if nearly every available policy lever were pulled,” said Debbie Weyle, U.S. acting director of the World Resources Institute. “Assertive action by states and cities will be essential to achieving this goal.” The Climate Action Tracker project calculates that the U.S. must cut total emissions by at least 62% below 2005 levels by 2030 to be compatible with a goal of limiting warming to 1.5 degrees Celsius. President-elect Trump is expected to take the U.S. out of the Paris Agreement once again.

2. Montana Supreme Court sides with youth climate activists in landmark case

The Montana Supreme Court yesterday handed a win to a group of 16 youth climate activists, upholding a lower court’s ruling in the landmark Held V. Montana case that the state was violating residents’ constitutional right to a clean environment by permitting fossil fuel projects without considering the climate consequences. The state had argued that its greenhouse gases were a drop in the bucket compared to global emissions, with negligible effects on the climate, but in a 6-1 ruling, the justices disagreed and affirmed the lower court’s decision. “Montana’s right to a clean and healthful environment and environmental life support system includes a stable climate system,” chief justice Mike McGrath wrote.

  • 3. EPA approves California’s 2035 gas car ban

    The Environmental Protection Agency this week gave the green light for California to enforce its ban on sales of new gas-powered cars by 2035. About a dozen other states, plus some major automakers, adhere to California’s strict vehicle emission standards, so the decision could have broad implications. But it also is likely to be revoked by the incoming Trump administration, and a long court battle could ensue.

    4. Report: Off-grid solar and storage could power AI data centers

    A new report from a group of leading climate tech and microgrid development firms examined the feasibility of using off-grid solar and storage to provide clean power for AI data centers. It found solar microgrids would cost nearly the same as using off-grid natural gas turbines, could be built on a shorter timeline as opposed to rolling out new grid connections, and are “enormously scalable.” “We found that there is enough available land in the southwest U.S. alone that is close to roads and gas pipelines to build 1,200 gigawatts of offgrid solar microgrid data center capacity, far more than will be needed for the foreseeable future,” said Zeke Hausfather, lead climate researcher at Stripe. Here’s a look at the varying “time to operation” estimates from the report:

    OffgridAI

    And speaking of data centers, Oklo, a nuclear startup chaired by Open AI’s Sam Altman, has secured a 20-year agreement to supply power to data center operator Switch Inc. Under the deal, Oklo will build small modular reactors that can supply up to 12 gigawatts of electricity and come online by 2030. Caveat: The Financial Times noted that the deal “is non-binding and the company’s technology is years from production.”

    5. Trump advised to nix environmental reviews for some mining projects

    President-elect Trump’s advisers are telling him to let federally funded critical minerals projects go ahead without environmental reviews, Reuters reported. Nixing the review process currently required under the National Environmental Policy Act (NEPA) could speed up mining projects and help cut U.S. dependence on China for critical minerals used in clean tech like electric vehicles, but it could also allow developers to ignore climate change and environmental justice considerations.

    U.S. Weighs Banning Foreign Inverters

    Current conditions: As a dangerous heat dome settles over the central and eastern United States, evapotranspirate, or “sweat,” from corn has rendered Iowa and Illinois more humid than the Amazon • Temperatures just topped 100 degrees Fahrenheit in Zagreb, where intense thunderstorms are deluging the Croatian capital today • Hanoi, Vietnam, is in the midst of a week of severe thunderstorms.

    THE TOP FIVE

    1. U.S. weighs banning foreign inverters

    In May 2025, Reuters broke news that the U.S. government had discovered rogue communications devices in the inverters that converted the direct current flow of electricity from certain Chinese-made solar panels to the alternating current needed to patch the generators onto the grid. Now, more than a year later, Reuters is out with another scoop indicating that the Trump administration is preparing to slap new import restrictions on foreign-made inverters, particularly from China. The prohibition being drafted by the Federal Communications Commission would apply to all new foreign models of inverters and could be published as early as this year, unnamed sources told the newswire.

    Congress Never Meant to Design This

    The Supreme Court keeps changing the terms of the deal between the legislative branch and the executive.

    Congress Never Meant to Design This

    The Supreme Court ended its 2025–2026 term today, issuing a flurry of rulings on its most controversial cases. Most significantly, it rejected President Trump’s attempt to overturn birthright citizenship, preserving the 14th Amendment as it has been read for more than a century. It also struck down restrictions on how much political parties can spend in coordination with candidates — a change that could shape political strategies in November’s midterm election.

    But I suspect that the year’s most important ruling for energy and climate policy came … yesterday. In a 6-3 ruling, the court’s conservative majority allowed President Trump to fire the commissioners of independent agencies without cause. Although the case concerned the Federal Trade Commission, it will matter for every independent agency that governs energy and climate policy.

    My Extremely Hot European Vacation

    I decided to go to Italy in June with my husband, my 9-month-old daughter, and my 69-year-old father. What could go wrong?

    The start of a vacation really begins 10 days before departure, when your arrival date first appears on your weather app. Like the turning over of a tarot card, it is this initial forecast that hints at the potential character of your trip — whether your beach vacation might be ruined by rain, or if spring break will fall this year during an unanticipated cold spell.

    For our recent trip to Bologna, Italy, my family and I seemed to have pulled one of the worst cards in the deck: Our weather apps suggested early on that the high would be near 100 degrees Fahrenheit on the weekend of our arrival.
