US EPA Warm Program

The Environmental Protection Agency (EPA) provides a Waste Reduction Model (WARM) to calculate the environmental impacts of end-of-life options for products, including plastics. The US EPA WARM calculates GHG emissions for source reduction, recycling, waste-to-energy, and landfill end-of-life options. The US EPA WARM provides information about recycling, sources reduction, waste-to-energy, and landfill processes. WARM calculations are available in web-based calculator and as a Microsoft Excel spreadsheet. WARM has databases for over 45 material types and GHG emissions are provided in metric tons of C02eq or metric tons of carbon equivalent (EPA Waste Reduction Model 2013).
