Reporting your greenhouse gas emissions
The information below will help you report your facility's emissions for the required greenhouse gas (GHG) reporting program. If you're a transportation fuel supplier, you have special reporting instructions that you can view on our transportation fuel supplier greenhouse gas reporting page.
Some facilities that are required to report their emissions to us are also required to report to the EPA. Please visit their website for more information about the EPA greenhouse gas reporting program.
