GHG Reporting

Home » News & Events » GHG Reporting

Greenhouse gases trap heat and make the planet warmer. The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation. EPA tracks total U.S. emissions by publishing the Inventory of U.S. Greenhouse Gas Emissions and Sinks. This annual report estimates the total national greenhouse gas emissions and removals associated with human activities across the United States.

Who is required to report?

Sites listed as a specific source category or potentially any fossil fuel burning sources (singular or collectively) can be required to report. The following list shows each criteria a facility must meet to be required to report:

  • Source category is listed under 40 CFR 98 Table A-3.  
  • Source category is listed under 40 CFR 98 Table A-4 and emits 25,000 metric tons of CO2e or more per year in combined emissions from all applicable sources listed in Table A-3 and A-4.
  • If Table A-3 and A-4 do not apply to the facilities fuel burning sources, only stationary fuel combustion sources should be evaluated. All of the following criteria needs to be met in order for reporting to be required:
    • Aggregate maximum rated heat input capacity is 30 MMBtu/hr or greater.
    • The facility emits 25,000 metric tons of CO2e or more per year in combined emissions.

When and where to submit GHG Reports? 

GHG Reports are required to be submitted by March 31st of each year. The reports are required to be submitted to EPA through the electronic Greenhouse Gas Reporting Tool (e-GGRT). This program can be found in the following link (click here).
