Who is suing whom
Climate litigation has grown into several distinct families of cases. States, cities, and counties have sued oil and gas producers under state consumer protection and nuisance theories, and years have been spent fighting over whether those cases belong in state or federal court and whether federal law displaces them. Individuals and advocacy groups have sued governments, sometimes relying on state constitutions; New York added an environmental rights provision to its constitution, and plaintiffs have begun invoking it. Developers face challenges arguing that environmental review of a project understated its greenhouse gas effects. Federal climate rules have also changed sharply, and those changes have drawn legal challenges of their own.
New York's own climate laws in court
New York has an ambitious statewide climate law with emission targets, and groups have gone to court over how and when state agencies carry it out. The state's climate superfund law, which seeks payments from large historical emitters toward adaptation costs, has been struck down by federal courts in challenges brought by other states, industry groups, and the federal government, and appeals may follow. Because these cases are active, any statement about what a law currently requires should be checked against the latest rulings before you rely on it. Businesses with operations in the state often feel these laws first through permits, reporting obligations, and contract terms rather than through a lawsuit with their name on it.
Where we start with you
Most clients come to us with a narrower question than the headlines suggest: a complaint naming the company, a permit challenge, a subpoena for internal documents, or a contract clause tied to climate rules. We begin by identifying which kind of matter it is, what forum it sits in, and what deadlines apply, since responses to complaints and petitions run on fixed schedules. If documents are being requested, we look at what the company has said internally and publicly about emissions and climate risk, because consistency between the two tends to become the center of these cases. We also check whether insurance or indemnity may respond.
