U.S. EPA Municipal Solid Waste (MSW) Decision Support Tool(Excel-based, not publicly available). Intended for use by solid waste planners to analyze and compare MSW management strategies with respect to GHGs, cost, and other environmental impacts. Supporting information:
- Application of the U.S. Decision Support Tool (DST) for Materials and Waste Management By Thorneloe, S. Weitz, K. and Jambeck, J. 2007. Paper illustrates how the MSW-decision support tool (DST) can be used by evaluating ten management strategies for a hypothetical medium-sized community - to compare the life-cycle environmental and cost tradeoffs.
- Application of Life Cycle Management to Evaluate Integrated Municipal Solid Waste
- Sound Resource Management's Measuring the Environmental Benefits Calculator (MEBCalc™) is proprietary software for computing the environmental footprint of a community’s municipal solid waste (MSW) management system, from collection through final disposition of each discarded product or packaging material. Environmental impacts covered in the footprint include climate change as well as public health (respiratory disease, cancer, and toxicity), ecosystem toxicity, waterway nutrification, and acid rain.
- Clean Air Cool Planet Campus Calculator (Excel-based). Includes a wide range of emission and cost calculations for many activities, including power usage, transportation, waste management and offsets. The waste management portion of the calculator uses emission factors from WARM, but does not account for upstream emissions. The tool only calculates emissions from direct waste management either by landfilling or incineration. Includes offsets for composting. Also includes benefits (derived from the Environmental Defense Fund paper calculator) for using recycled content paper.

This section provides studies or examples of how product or activities contributing to GHG emissions accounting or reductions have been measured and presented.
Note that GHG product-related emissions listed here should be third-party verified, and this Wiki development group has not endorsed any of these products, nor verified any of the product GHG reporting. It is intended that some of these product examples may be useful in crafting procurement policies.
Towards a Sustainable, Prosperous King County 2010 Annual Report King County (WA) produces an annual report of the county's
Climate Change, Energy, Green Building and Environmental Purchasing Programs. They discuss their 2010 greenhouse gas emissions or reductions, from non-transit activities, such as solid waste diversion to composting, and recycling, and green building.

- Life Cycle Analysis (LCA) of Packaging Options for Shipping Soft Goods in E-commerce and Catalog Sales evaluated the environmental burdens of different options for shipping non-breakable items in an e-commerce/catalog order fulfillment environment. It demonstrates the importance of waste prevention, and shows that when comparing dissimilar materials, recyclability and recycled content don't always correlate to reduced environmental impacts.
- Weyerhaeuser Company's Product Environmental Profiles documents the relative carbon footprint (and other environmental impacts) of ten of their products (normalized per air-dry metric ton of product)
- LCA of Drinking Water Delivery Options compares the environmental impacts of different methods of delivering drinking water to households, including single use bottles (recyclable and/or compostable), vs. tap water methods, with details on the impacts and benefits of different resin choices and end-of-life management methods. A supplemental report demonstrates the moderate benefits from recycling single-use PET water bottles, but the far greater benefits of avoiding them in the first place.
