Tools for Measuring Greenhouse Gases Updated

The Greenhouse Gas (GHG) Equivalencies Calculator was updated by EPA February 2024. The calculator allows users to convert emissions or energy data to the equivalent amount of carbon dioxide (CO2) emissions from using that amount. The calculator helps you translate abstract measurements into concrete terms you can understand, such as the annual emissions from cars, households, or power plants. It incorporates anesthetic gases as well as updates to emission factors. The Spanish version of the calculator is updated as well. Open the Calculator

Also just updated are EPA’s Greenhouse Gas (GHG) Inventory Tools for Local, Tribal, and State Governments. They are a series of interactive spreadsheet models designed to help state, local, and tribal governments develop GHG emissions inventories. These interactive spreadsheet tools provide a streamlined way for governments to update an existing inventory or complete a new inventory. The tools are pre-programmed with default emission factors and system assumptions needed to calculate emissions.
