This workshop presents a framework for considering environmental and social impacts of manufacturing, food and travel through a collective Web-based tool for life-cycle assessment and supply-chain transparency (www.sourcemap.org). Principles of environmental and social sustainability will be presented, including evidence from carbon footprint assessments in hospitality, retail, and product design. Participants will learn how to research and conduct life-cycle assessment for consumer products, foods, and transportation and make map-based visualizations for sharing through online social networks. The course is followed by a working session for hands-on training for those interested. Please bring a laptop computer with WIFI and Firefox/Safari/Chrome browser installed.
