In 2024, New York State enacted several laws aimed either at dealing with the adverse impacts of climate change such as extreme heat and increasingly severe and frequent storms or at helping to mitigate greenhouse gas emissions to avoid or minimize the adverse impacts. The final bill signed by Governor Kathy Hochul in 2024 was the most high-profile of these laws—the Climate Change Superfund Act, which will require fossil fuel companies to pay for adaptation measures.

Other new laws last year related to extreme heat in schools and prisons, food waste, expanded polystyrene containers, community gardens, and native plant seeds. These and other new and amended environmental and energy laws—as well as notable vetoes—are discussed in this article.
