Statewide Greenhouse Gas Emissions Report

New York's Emission Reduction Requirements

The Climate Leadership and Community Protection Act of 2019 establishes certain emission reduction limits as well as additional goals to address climate change. These requirements and goals include:

  • Limit statewide greenhouse gas emissions to 60% of 1990 levels by 2030 and 15% by 2050
  • Achieve net zero greenhouse gas emissions across New York State's economy

2021 Statewide GHG Emissions Report

The Climate Leadership and Community Protection Act directs DEC to issue an annual report on statewide greenhouse gas emissions, pursuant to Section 75-0105 of the Environmental Conservation Law. This current report covers the years 1990 through 2019. The emission information will also be made available for download from Open Data NY (leaves DEC website).

The Annual Reporting Process

DEC will issue an annual report on statewide greenhouse gas emissions following the requirements of the Climate Leadership and Community Act and in alignment with the latest guidelines from the Intergovernmental Panel on Climate Change (leaves DEC website). This report will cover all sources in the state, from the base year of 1990 to two years before the current year. The report will include the relative contribution of each type of greenhouse gas and each type of source to the statewide total. Per the law, statewide greenhouse gas emissions must include emissions produced within the state from anthropogenic sources and emissions outside of the state associated with imported electricity and the extraction and transmission of imported fossil fuels. Emissions must also be expressed in terms of tons of carbon dioxide equivalents using a 20-year Global Warming Potential. As it is the goal of the State to achieve net zero emissions, this annual report also provides information on emission removals from anthropogenic sources.

Generally, DEC's report will follow the annual release of core datasets provided in the Spring by the U.S. Environmental Protection Agency (leaves DEC website) and the U.S. Energy Information Administration (leaves DEC website). DEC will accept feedback at any time during the year. In addition, three public hearings were held in 2021 regarding the methodology and analysis as well as the structure and scope of the report. Additional public hearings may be provided periodically.
