Environmental Law: 37% Rise in Claims by 2025

Federal environmental lawsuits are spiking, a recent analysis shows a 37% jump in filings in U.S. federal courts between 2020 and 2025. That’s a huge signal of a major shift in how we think about and file lawsuits for injuries. This surge points to the rising importance of climate-rights jurisprudence and the tangled web of new environmental injury claims we’re going to see even more of through 2026. For people and businesses trying to operate in this space, the ground is moving fast.

Data Point 1: The Expanding Definition of “Injury”

A key trend in climate-rights law is how much the definition of an “actionable injury” has stretched. Traditionally, environmental cases were about clear-cut property damage or getting physically sick from pollution. Now, the courts are beginning to recognize harms that are less direct but just as real. A 2025 Environmental Law Institute (ELI) report found that over 15% of new climate lawsuits in state courts included claims for mental health impacts, like anxiety or PTSD from extreme weather events. That’s up from less than 5% just five years ago. We’re talking about the deep psychological toll of being displaced, the constant anxiety of waiting for the next disaster, and the real grief people feel watching the environment collapse around them.

In my view, courts are finally becoming more receptive to arguments that connect environmental chaos to non-physical suffering. This opens up new avenues for plaintiffs to get recovery that acknowledges the full damage done, but it also forces defendants, especially corporations, to re-evaluate their potential liabilities far beyond just pollution controls. Of course, proving a mental health claim requires bulletproof medical and psychological expert testimony that can draw a straight line from a specific environmental event to a documented psychological injury, but the groundwork is being laid and the precedents are being set.

Data Point 2: Infrastructure Vulnerability and Economic Losses

The economic fallout from climate change is now a lived reality, and the legal system is catching up. The American Society of Civil Engineers (ASCE) made this painfully clear in their 2025 Infrastructure Report Card, which showed that cumulative economic losses from climate-related infrastructure damage in coastal U.S. areas shot past $100 billion between 2020 and 2024. That number covers everything from buckled roads and failing bridges to fried public utilities and ruined private property after bigger storms and rising sea levels. These aren’t just one-off accidents. They’re symptoms of a systemic weakness that’s now being tested in court.

Legally, this data means we’re seeing a real push to hold entities accountable for not adapting infrastructure to climate risks that were clearly foreseeable. We’re seeing lawsuits against cities for having inadequate stormwater systems that lead to flooding or against utility companies for outages caused by predictable storms. The core legal argument is usually negligence: did the responsible party know (or should they have known) about the risk, and did they do anything reasonable to prepare? Here in Georgia, a homeowner whose house keeps flooding because the city’s drainage system is overwhelmed might sue under inverse condemnation or nuisance, arguing the city’s failure to act has effectively taken their property without compensation. We’ve seen a definite uptick in these kinds of municipal liability cases right here in Fulton County Superior Court, which shows judges are willing to hear them out.

Data Point 3: The Rise of “Failure to Warn” and “Failure to Adapt” Claims

A major development in 2026 is how many lawsuits now focus on “failure to warn” and “failure to adapt” to climate risks. According to a 2025 survey from the National Association of Attorneys General (NAAG), state attorneys general have launched 23 new investigations or suits against fossil fuel companies just since 2024, all alleging some form of climate-related deception or hiding risks from investors and the public. This tells you that public prosecutors are now aggressively digging into what these companies knew about climate change and when they knew it.

These cases have real teeth because they often force the discovery of decades of internal corporate documents and scientific research. The theory of the case is that if a company or a government agency had scientific data about climate risks but didn’t warn people or change its own operations, it can be held liable for the damage that followed. This helps plaintiffs draw a clearer line between corporate behavior and environmental harm. It addresses the systemic contributions to the climate problem, not just an isolated pollution event. We’re seeing these claims get past the initial filing stage and into discovery, which means the courts think they have merit.

Data Point 4: Regulatory Gaps Fueling Private Litigation

Even with all the public attention, government regulations are way behind the science and the speed of environmental change. A 2026 analysis from the EPA (you can find it over on epa.gov) confirmed that over 60% of U.S. states still don’t have complete, legally binding climate adaptation plans. That regulatory vacuum is what’s driving a lot of private lawsuits.

When the government drops the ball on regulation, civil lawsuits often have to pick it up. If a state fails to pass rules to protect its citizens from climate harms, people are turning to the courts themselves. This shows up as class-action suits against polluters or even lawsuits against the government agencies for failing to do their job. For instance, if a Georgia community sees a spike in health problems from poor air quality that’s made worse by climate change and a lack of local action, those residents could band together and sue. The tension is clear: while legislatures are stuck debating policy, the courts are out there actively making environmental law by deciding individual and collective injury claims. Private litigation is a necessary tool for justice when other systems break down.

Challenging the Notion of “Unforeseeable” Harm

The old defense argument that climate harms are ‘unforeseeable’ or an ‘act of God’ just doesn’t hold water anymore, especially in 2026. I fundamentally disagree with it. The scientific consensus has been solid for decades. The Intergovernmental Panel on Climate Change (IPCC) reports, which anyone can read at ipcc.ch, have consistently laid out detailed warnings about rising temperatures, sea levels, and extreme weather. For a large corporation or government body with access to all that data to claim something was “unforeseeable” is becoming a very tough sell in court. The legal standard isn’t about having a crystal ball. It’s about whether a reasonable entity should have anticipated the general *type* of harm. Given the science we’ve had since the late 90s, many of these impacts were actively predicted. The courts are now shifting the burden, making defendants prove *why* they couldn’t have reasonably seen this coming. This shift demands proactive responsibility, not reactive excuses.

And the argument that you can’t pin the blame on anyone because the problem is too big? That needs a serious rethink. Though climate change is a global problem, some specific industries and companies have contributed a wildly disproportionate share of the emissions. New legal strategies are using attribution science to connect specific emissions to specific local impacts, making the causation argument much stronger in court. It’s a difficult and expensive task, requiring top-tier expert witnesses and complex models, but it is becoming more and more possible. The convenient fiction that a huge problem can’t be litigated is falling apart. The law is finding ways to assign responsibility.

Practicing in this area of climate-rights jurisprudence means you have to have a deep grasp of the evolving legal theories, the hard science, and the specific statutes here in Georgia. The sheer volume and complexity of these cases mean that both individuals and businesses need to be ready for tough, drawn-out legal battles. Proactive risk assessment and good legal counsel are essential for protecting assets and ensuring accountability in a world that is changing right under our feet.
