Durham, the fourth largest city in the North Carolina State after Charlotte, Raleigh and Greensboro, has dedicated efforts to improve the environment with increasing population. As our client, the Durham City-County Sustainability Office works with other government local departments and the community in Durham to ensure environmentally friendly and sustainable development in the City and County. In 2007, the Sustainability Office adopted Durham’s Greenhouse Gas Emissions Reduction Plan initiated by ICLEI, and the Office hired a Sustainability Manager in 2008, who is our direct client contact person, to help implement the plan and achieve the ambitious goals for reducing greenhouse gas emissions. Six years after the 2007 plan, we assisted the client to evaluate how the plan was implemented and what progress have been made for different projects in Durham, based on the previous Durham GHG inventory results and the new re-inventory methodology provided by ICLEI.
