New York Mayor Michael Bloomberg (I) and World Bank President Robert Zoellick announced June 1 that the C40 Cities Climate Leadership Group joined the World Bank in an agreement to ease procedures for cities to obtain financing for climate-related projects. The lack of a consistent approach has made it difficult to assess the plans for funding. The next day, the C40 Cities Climate Leadership Group and the ICLEI-Local Governments for Sustainability announced that they will work together to create a standard to measure and report community-level greenhouse gas emissions.
