"WARM is a tool that provides high-level comparative estimates of the potential GHG emissions, energy savings, and economic impacts of materials managed in baseline and alternative materials management practices, including source reduction, recycling, composting, anaerobic digestion, combustion, and landfilling. The model estimates emissions, energy units and economic factors across a wide range of material types commonly found in municipal solid waste and construction and demolition debris in the following categories: Metric tons of carbon dioxide equivalent (MTCO2E), Energy units (million British Thermal Unit - BTU), Labor hours, Wages ($), and Taxes ($). WARM is currently available as a downloadable Microsoft Excel spreadsheet. Potential GHG savings are calculated by comparing the estimated emissions associated with managing materials under an alternative scenario with the estimated emissions associated with the user’s baseline scenario (i.e., current practices), as opposed to simply multiplying the quantity of materials managed by an emission factor. For example, the GHG savings of recycling one (1) short ton (standard U.S. ton) of aluminum cans instead of landfilling them would be calculated as follows: (1 short ton × -9.13 MTCO2E/short ton) - (1 short ton × 0.02 MTCO2E/short ton) = -9.15 MTCO2E WARM is periodically updated as new information becomes available and new material types are added. Users may refer to the model history to better understand the differences among various versions of WARM. WARM was last updated in December 2023. WARM was not developed for and should not be used for final site-specific materials management decisions, when other human health and environmental impacts of the different management methods may need to be considered (such as air pollution, water pollution, noise pollution, etc.). WARM is a comparative tool rather than a comprehensive measurement tool. It also should not be used for developing GHG inventories, which need to establish a baseline and measure reductions over time on an annual basis for an entity."
