  • EPA Improves Calculators to Measure Impact of Pollution Prevention Activities

    February 7, 2023 - Today, the U.S. Environmental Protection Agency (EPA) released three improved pollution prevention (P2) calculator tools.

    These tools — the P2 Cost Calculator, the P2 Greenhouse Gas Calculator, and the P2 Calculator for Reductions in Hazardous Substances, Pollutants and Contaminants — convert information on P2 activities at a business, such as reductions in energy use, into information on cost savings and pollution reductions. They help P2 grantees, technical assistance providers, and others measure environmental outcomes and economic performance related to P2 activities.

    The updates to the Cost Calculator and the Greenhouse Gas Calculator include:

    The updates to the Reductions Calculator include expanded categories of pollutants and releases — including hazardous materials used, hazardous wastes, air emissions, water pollutants, and solvent remanufacturing — that EPA tracks and measures.

    The calculators use Microsoft Excel and perform best when used with the most current Excel version.
