🌿 Climate & Environment · Monthly Roundup

March 2026

March 2026 delivered a month of compounding climate pressures across legal, political, scientific, and geopolitical fronts. In the United States, the Trump administration's rollback of foundational environmental protections triggered an unprecedented coalition of states into court, while new research quantified the staggering economic toll of American carbon emissions over three decades. Internationally, the World Meteorological Organization confirmed that every major climate indicator reached new extremes in 2025, prompting a rare declaration of climate emergency from the UN Secretary-General. From Germany's missed targets to New York's policy retreats, the month underscored a widening and increasingly dangerous gap between climate commitments and climate action.

Trends

The most dominant theme of the month was the collision between legal frameworks and political will: the lawsuit over the EPA's endangerment finding repeal and New York's climate law delays both illustrate how even well-established climate mandates are now vulnerable to rollback under sustained political pressure. A second major trend was the expanding geography of climate accountability — from the $10 trillion in damages attributed to US emissions to the first-ever carbon accounting of a military conflict, the month saw a surge in research linking specific actors and activities to quantifiable climate harm. Third, the science continued to outpace the policy response: the WMO's record-breaking indicator report and the sweeping global study on climate impacts on daily life both reinforced that observed warming is tracking at or beyond worst-case projections, even as governments in Germany, the US, and the UK struggled to deliver on basic near-term commitments.

Looking Ahead

The DC Circuit lawsuit over the EPA's endangerment finding will be one of the most closely watched legal proceedings of the year, with early procedural developments likely to emerge in April — its outcome could fundamentally reshape the architecture of US environmental law. Germany's missed 2025 targets will face renewed scrutiny as the country's new government confronts a mandatory Climate Protection Act review, while England's land-use framework moves toward implementation and the first stakeholder disputes over its trade-offs are likely to surface. The Ohio gas megaplant and Iran conflict emissions story will both demand follow-up, as financing timelines and post-conflict environmental audits are expected to progress in the coming weeks.

Top Stories

The ten stories that defined the climate and environment conversation in March 2026 span courtrooms, legislatures, and battlefields — reflecting just how broadly the climate crisis now intersects with every domain of public life.

US states sue Trump EPA over decision to repeal bedrock climate finding

Twenty-four states, along with a dozen cities and counties, have filed suit against the Trump EPA over its decision to rescind the endangerment finding — the foundational scientific ruling that greenhouse gases pose a threat to public health. Without that determination, which dates to 2009, the legal basis for the vast majority of federal climate regulations effectively collapses. The case, filed in the DC Circuit Court of Appeals, represents one of the most consequential legal battles over climate policy in US history.

Q&A: What England’s new ‘land-use framework’ means for climate, nature and food

England's long-awaited land-use framework sets out how the country's countryside will be managed to balance competing demands for food production, nature recovery, and clean energy. Just 1% of England's land would need to be dedicated to renewables to meet the UK's climate targets, challenging fears that solar and wind farms threaten agricultural output. The framework represents a significant policy shift in how government coordinates land decisions — with implications for farmers, conservationists, and the net-zero transition alike.

New York’s Governor Pushes to Delay a Key Portion of the State’s Climate Law

New York Governor Kathy Hochul is moving to delay key provisions of the state's landmark Climate Act, which mandates a 40 percent reduction in greenhouse gas emissions by 2030 and 85 percent by 2050. The rollback signals growing political tension between ambitious climate commitments and the practical and economic pressures of implementation. For a state that positioned itself as a national leader on climate policy, the retreat raises serious questions about the viability of its own targets.

Report Shows Earth’s Climate is Out of Balance, as Indicators Hit New Extremes

Last year marked another record-breaking chapter in climate breakdown, with every major indicator — from ocean heat to sea levels — hitting new extremes, according to the World Meteorological Organization's latest State of the Global Climate report. U.N. Secretary-General António Guterres declared a state of climate emergency in response, warning that Earth is being pushed beyond its limits. The findings underscore the widening gap between the scale of the crisis and the pace of global action.

US has caused $10tn worth of climate damage since 1990, research finds

Global warming's price tag has a clear address. New research finds the US is responsible for $10 trillion in climate-related economic damages since 1990, the largest share of any nation, owing to its status as history's top cumulative carbon emitter. A quarter of that damage has rebounded onto the US itself, raising urgent questions about domestic accountability alongside America's international obligations.

Trump to revoke protections for endangered species in Gulf of Mexico

The Trump administration is invoking the rarely used "God Squad" — a panel of senior officials with the power to override the Endangered Species Act — to strip protections from wildlife in the Gulf of Mexico. The move, framed as a national security measure, would clear the way for expanded oil and gas drilling in the region. Dozens of species, including Rice's whales, whooping cranes, and sea turtles, face potential extinction as a result.

Germany misses climate targets as emissions barely fall in 2025

Germany's greenhouse gas emissions fell by just 0.1% in 2025, falling well short of the reductions required under the country's own Climate Protection Act. The near-stagnation marks another year of missed targets for Europe's largest economy, drawing sharp criticism from the environment minister. The figures raise serious questions about Germany's ability to meet its longer-term climate commitments without significant policy intervention.

5m tonnes of CO2 emitted in just 14 days of US war on Iran, analysis finds

The first climate analysis of the US-Israel conflict with Iran finds the war generated 5 million tonnes of CO2 in just 14 days — a pace that outstrips the combined annual emissions of 84 countries. The findings underscore how modern warfare, through airstrikes, drone operations, and missile campaigns, represents a largely overlooked driver of carbon budget depletion. As global climate negotiations fixate on industrial emissions, the analysis raises urgent questions about whether military conflicts should face the same scrutiny.

Trump Deal for a $33B Gas Megaplant in Ohio Faces Huge Hurdles

A proposed $33 billion natural gas megaplant in Ohio, touted by the Trump administration as a major energy win, faces serious questions about its viability. Financial risks, unresolved permitting challenges, and uncertain access to key equipment have analysts and critics skeptical the project will ever reach completion. The announcement may signal political ambition more than industrial reality.

Global warming already impacts daily lives around the globe, study finds

Global warming is no longer a distant threat — it is actively disrupting the daily lives of people across the planet, according to a sweeping new study drawing on 75 years of climate data. Researchers found measurable links between rising temperatures and impaired everyday activity, from work and sleep to health and mobility. The findings arrive as a punishing heat wave grips the U.S. West and forecasters warn of a potentially record-breaking El Niño season ahead.
