Solid Waste Emissions Estimation Tool (SWEET) version 2.0

The Solid Waste Emissions Estimation Tool (SWEET) is an Excel-based tool that quantifies emissions of methane, black carbon, and other pollutants from sources in the municipal solid waste sector. The tool provides emissions and emissions reduction estimates at the project-, source-, and municipality-level. Cities can use this information for multiple purposes, including establishing a baseline scenario, comparing a baseline scenario to as many as four alternative scenarios, analyzing specific projects for potential emissions reductions, estimating the contribution of activities in the waste sector to overall city emissions reduction goals, and tracking progress over time, among other things.

SWEET was developed by the U.S. Environmental Protection Agency (with assistance from Abt Associates and SCS Engineers) on behalf of the Climate and Clean Air Coalition Municipal Solid Waste Initiative.

Version 1 of the tool was released in October 2017. The current version, version 2.0, was released in February 2018.
