New York is the fourth-most populous state in the nation, with nearly 20 million residents, and the 27th-largest state by area, with a total area of 54,556 square miles. The area of present-day New York had been inhabited by tribes of the Algonquians and the Iroquois Confederacy Native Americans for several thousand years by the time the earliest Europeans arrived.
Even under a low-emissions scenario, New York State will continue to experience substantial climate change impacts.
Warming faster than the national average, New York’s average temperatures have increased by 2.6°F over the last century, driving more frequent and intense heat waves. As the New York State Climate Impacts Assessment details, the health risks associated with extreme heat will disproportionately impact low-income households, outdoor workers, unhoused populations, and individuals with chronic medical conditions. Concurrently, the state faces a projected rise in annual precipitation and extreme weather events; precipitation has already climbed 10% to 20% over the past century and is on track to increase by another 6% to 17% by 2100.
Furthermore, sea levels along the New York coastline have risen one foot over the past century and are projected to surge by an additional 1 to 2 feet by 2050. This accelerating sea level rise intensifies severe storm surges, chronic coastal flooding, saltwater intrusion, and groundwater contamination. These compounding hazards pose escalating public health risks and threaten critical infrastructure, leaving "residents and communities that are marginalized or suffer from legacies of displacement or discrimination" highly vulnerable to the worst impacts of environmental degradation.
New York consumes less total primary energy per capita than all but two other states, trailing only California and Rhode Island. The state’s utility-scale electricity generation portfolio relies on a diverse mix of fuel resources: natural gas provides the bulk of the power at 47%, followed closely by hydropower at 21%, nuclear power at 20%, solar energy at 6%, and wind power at nearly 5%, while biomass contributes roughly 1% and petroleum accounts for a minor 0.2%. This baseline reflects a dramatic grid transformation, as nuclear generation declined following the retirement of the Indian Point nuclear power plant in 2021, while coal-fired generation dropped to zero after the state’s final coal plant retired in 2020.
Overall, New York ranks fifth in the nation for renewably sourced electricity generation, which contributes about one-third of total in-state generation. The state's solar expansion is heavily anchored by its rank as fifth in the nation for small-scale and community solar deployments, with solar generation first exceeding biomass in 2019. This renewable momentum is poised to accelerate through massive maritime infrastructure investments; New York’s first offshore wind farm, The South Fork Wind Farm, came online to power 70,000 homes, and two more large-scale projects are scheduled to enter operation in 2027. Together, these two upcoming developments—Empire Wind 1 and Sunrise Wind—will generate enough clean, zero-emission electricity to power over 1.1 million New York homes, marking a massive leap forward in the state's transition toward a carbon-free electrical grid.
To bridge this expanding clean grid with transport infrastructure, the Public Service Commission authorized a major utility-funded EV charging initiative designed to support the state's adoption framework of 850,000 Zero Emission Vehicles (ZEVs). It is likely the state will call for an expansion of mass transit and an accelerated shift to electric vehicles, which are already promoted with rebates and heavy investments in charging infrastructure.
New York has a current statutory mandate to secure 9,000 megawatts of offshore wind capacity by 2035, anchored by five major offshore wind projects in active development that will collectively generate enough electricity to power over two million homes. To support this pipeline, Governor Kathy Hochul announced a comprehensive 10-Point Action Plan, driving a historic buildout of regional transmission infrastructure, the expansion of New York's green technology workforce, and the official launch of the state's Offshore Wind Master Plan 2.0.
However, regulatory realities have forced a shift in expectations. In their official program review under the Clean Energy Standard, the Public Service Commission (PSC) and NYSERDA explicitly acknowledged that “a delay in achieving the 70% goal”—powering 70% of the state's electricity with renewables by 2030—“may be unavoidable,” subsequently proposing an extended target framework out to 2033. The language of the official state review attributes this expected regulatory delay directly to “global economic issues,” reflecting the real-world impact of macroeconomic inflation, high interest rates, and project contract re-bidding cycles that have temporarily hamstrung early land-based and offshore developers.
New York adopted its first Renewable Portfolio Standard in 2004, replacing it in 2016 with the Clean Energy Standard, which was subsequently expanded in 2019 to meet the strict legal requirements of the Climate Act. Aggregated implementation metrics are continuously published via the NYSERDA Clean Energy Dashboard.
At the end of June 2019, the legislature passed the Climate Leadership and Community Protection Act (CLCPA)—also known as the Climate Act—which was signed into law by Governor Andrew Cuomo. In enacting this sweeping climate legislation, New York built upon regional frameworks pioneered by Maine, Oregon, Washington, Colorado, New Mexico, California, and New Jersey. The statutory roadmap originally mapped a vision of solar arrays, electric vehicle infrastructure, and widespread marine wind power by calling for:
The Climate Act established the Climate Action Council, a 22-member body that finalized its definitive Scoping Plan to coordinate these mandates, which directly informed the state's updated 2025 Energy Plan. Auxiliary bodies like the Climate Justice Working Group delivered the Disadvantaged Communities Barriers and Opportunities Report, while the Department of Environmental Conservation (DEC) formalized a strategic "social cost of carbon" metric.
According to the official New York State Climate Act Dashboard, tracking metrics indicate the state has achieved 61% of its emission reduction milestone, 62% of its renewable generation transition, 102% of its distributed solar footprint, 21% of its offshore wind pipeline, and 27% of its localized energy storage capacity. The DEC supports these transparency goals by publishing its comprehensive Statewide GHG Emissions Report alongside localized climate assessments.
State efficiency guidelines were expanded via Governor Hochul’s Executive Order 22, establishing the GreenNY Council to enforce sustainable purchasing and institutional waste reductions. Concurrently, New York voters approved the $4.2 billion Clean Water, Clean Air, and Green Jobs Environmental Bond Act, legally mandating that 40% of all capital benefits flow directly to state-designated Disadvantaged Communities. The state's baseline hazard tracking was updated via the comprehensive New York State Climate Impacts Assessment, joining focused resilience strategies including the Climate Affordability Study, the Extreme Heat Action Plan, and the federally backed Priority Climate Action Plan (PCAP).
Decarbonization expanded further when New York's pioneering All-Electric Buildings Act survived an intense industry-backed preemption challenge, with the U.S. Court of Appeals for the Second Circuit ruling in favor of the state on June 30, 2026. Following the formal court stay lifting on October 28, 2026, the law officially begins prohibiting fossil fuel connections in newly constructed low-rise developments, with high-rises scheduled to follow in 2029. To target localized emissions and small engines, Governor Hochul also signed the Electric Landscaping Equipment Rebate Program into law in late September 2026, enabling NYSERDA to distribute point-of-sale financial incentives to help commercial landscapers, school districts, and municipalities replace gas-powered equipment with battery-powered tools.
Despite these comprehensive frameworks, New York's clean energy implementation timeline has been heavily reshaped by recent court rulings and administrative adjustments:
Across New York State, entrenched discriminatory housing practices, historical redlining, and regressive zoning have disproportionately overburdened Black, Latino, and immigrant low-income communities with climate impacts. In Yonkers, for example, historically redlined neighborhoods suffer from a severe urban heat island effect, recording average surface temperatures nearly 3°F higher than areas that historically received robust investment. Low-income households, communities of color, immigrant communities, and rural populations experience heightened vulnerability to climate hazards while possessing fewer resources for adaptation and mitigation. The nine federally recognized Tribal Nations living in New York, alongside other Indigenous communities, face further compounding threats due to deep histories of land dispossession, ecological degradation, rising sea levels, and systemic social inequities.
A stark case study of environmental injustice occurred during Superstorm Sandy’s devastating impact on Red Hook, Brooklyn. In Red Hook—where over half of the population resides in public housing, 85% of residents are Black or Latino, and the poverty rate sits at 45%—prolonged municipal disinvestment, stark health disparities, and the neighborhood’s status as a food desert drastically compounded the catastrophe of the storm. Because climate scientists estimate that the severe flooding conditions experienced during Sandy could become frequent occurrences along the downstate coastline by the end of the 21st century, studying and mitigating climate change’s unequal impacts on overburdened communities remains a critical priority.
This systemic vulnerability extends directly to municipal utility infrastructure. The New York Civil Liberties Union (NYCLU) is actively engaged in a major advocacy campaign to confront a severe lead water crisis in Syracuse, where over 25% of sampled households show high levels of lead contamination. The crisis carries severe racial disparities, as Black children in Syracuse are nearly six times more likely than white children to present elevated lead blood levels. In February 2026, the NYCLU issued a public report card giving the city and state health regulators a failing "F" grade for historical mismanagement, forcing a newly seated municipal administration to accelerate line-replacement efforts in vulnerable zones.
To legally dismantle these patterns, grassroots coalitions including WE ACT for Environmental Justice and South Bronx Unite successfully won passage of the landmark Environmental Justice Siting Law (the Cumulative Impacts Bill). Following extensive regulatory development, the law officially took effect on June 12, 2026, making New York the second state in the nation (after New Jersey) to inject environmental justice mandates directly into state permitting. The law legally bars the Department of Environmental Conservation from issuing or renewing industrial permits if a cumulative impact review reveals a project will shift a disproportionate pollution burden onto a designated Disadvantaged Community. To insulate local communities against federal uncertainty, WE ACT has partnered with Columbia Law School’s Sabin Center for Climate Change Law to distribute model municipal legislative templates alongside its active 2026 Environmental Justice Agenda.
New York is a founding executive committee member of the U.S. Climate Alliance, a bipartisan coalition of 24 governors representing states and territories committed to implementing high-impact, state-led policies that advance the greenhouse gas reduction goals of the Paris Agreement. Additionally, New York operates as an active member of the Regional Greenhouse Gas Initiative (RGGI), which serves as an 11-state compact and stands as the first mandatory, cap-and-invest market-based initiative in the nation designed to systematically reduce carbon dioxide emissions from the electricity sector
We have made separate pages for New York City, the largest city in America, and for two fairly small towns, East Hampton and Southampton, which made early commitments (in 2014 and 2017 respectively) to 100% renewable energy.
