Waste Reduction Model (WARM)

WARM is a free tool that calculates and totals GHG emissions of baseline and alternative waste management practices—source reduction, recycling, combustion, composting, and landfilling. The model calculates in metric tons of carbon equivalent (MTCE), metric tons of carbon dioxide equivalent (MTCO2E), and energy units (million BTU) across a wide range of material types that compose municipal solid waste (MSW). WARM can help solid waste planners and organizations track and voluntarily report GHG emissions reductions from several different waste management practices.

WARM is available both on the Web and as a downloadable spreadsheet. Users can calculate greenhouse gas emission reductions by filling out the Online WARM worksheet. WARM can also be downloaded as a Microsoft Excel spreadsheet.

The WARM User's Guide will help you get up and running with the WARM software.

WasteWise Climate Presentation: Global Warming...Is a Waste!

This presentation explains the science and impacts of global climate change, and shows how WasteWise activities can help organizations reduce their impact on the global climate.

Greenhouse Gas Equivalencies Calculator

The U.S. Climate Technology Cooperation (supported by the Global Environment & Technology Foundation, the U.S. Agency for International Development, and the U.S. Environmental Protection Agency) developed a new online tool enabling users to translate GHG emissions reductions into real-life equivalents (i.e., barrels of oil, acres of forest preserved from deforestation, passenger cars not driven for one year, etc). Access the Greenhouse Gas Equivalencies Calculator.

Global Climate Change: Causes and Impacts

WasteWise developed Global Climate Change: Causes and Impacts (PDF) (2 pp, 99K, about PDF) based on information from the Pew Center on Global Climate Change's publications Exit EPA to educate WasteWise partners and the general public about the causes and impacts of global climate change.
