Within months of the Paris climate talks, more than 20 city officials from around the world gathered in Washington, D.C. for a "how-to" on inventorying sources of greenhouse gas emissions. The training – led by Raj Buch, practice lead for the Walton Global Sustainability Solutions Services – helped attendees determine where emissions cuts are most needed. Twenty-one city officials attended, from countries including Argentina, India, South Africa, Korea, Bolivia, China and Bangladesh. All of them were clients of World Bank, an organization that mainly finances Third World infrastructure projects and is concerned about the effects climate change will have on them. Bank officials asked the School of Sustainability to design and deliver a curriculum around this topic, as it had done for other topics in the past. The workshop will be produced in an online format, as well.
