The global nature of climate change warrants global action. Yet, that same scope can become an excuse for inaction. The U.S. Department of State has been instrumental in the international development of key climate policy, setting in motion global responses over the coming decades. This talk, instead, looks at the Department’s options to quickly lower its own greenhouse gas emissions, especially overseas. After compiling a global dataset that integrated source activities across organizational functions, a greenhouse gas inventory was built. Estimates of the emissions from Posts around the world will be shared, providing foundational benchmarks, and decision-making frameworks, for assessing effective emission reduction strategies. Two example cases will be presented to explore locally-effective approaches. These kinds of solutions may help overseas Posts reduce the Department’s greenhouse gas emissions to our planet’s atmosphere, demonstrating climate leadership through responsive changes in operational practices.
