This EPA web page contains several greenhouse gas emissions calculators from EPA and other organizations. These interactive calculators help estimate the greenhouse gas emissions of human activities, convert carbon emissions to equivalent units, and identify and compare emissions reduction options. The calculators vary greatly in complexity, scope, and intent. A brief description of each is provided to help you choose one or more that best meets your needs.
