Sara Hartwell

Ms. Hartwell is ana analytical chemist whose work at EPA has focused on the lifecycle relationship between climate change and end-of-life materials management. She managed EPA’s Waste Reduction Model (WARM, epa.gov/warm), a tool used to quantitatively estimate the climate and energy benefits of alternative end-of-life management scenarios. She used WARM to develop other tools to communicate the relationship between climate change and end-of-life materials management to specific user communities, including a consumer-facing tool that estimates the energy conservation benefits of recycling individual products (epa.gov/iwarm), and EPA’s Office Carbon Footprint Tool, estimating carbon footprints and providing suggestions for carbon-cutting actions (http://www.epa.gov/waste/partnerships/wastewise/carboncalc.htm). Ms. Hartwell has worked extensively with the private sector to communicate the climate – materials management connection, and to develop strategies for sustainable material management, especially in the packaging and retail sectors.
