Laurie Kerr advises on special Urban Green research and policy work. Kerr has extensive experience in urban sustainability policy. As Deputy Director for Green Building Policy at the NYC Mayor’s Office of Long Term Planning and Sustainability under Michael Bloomberg, Kerr helped develop PlaNYC, New York’s influential sustainability plan, and spearheaded the development of New York’s innovative green building and energy efficiency policies. These included the first comprehensive policies by any jurisdiction to address energy efficiency in existing buildings, the greening of New York’s codes and regulations, a clause that solves the splint incentive problem in commercial leases, and programs by city government and leading sectors to reduce greenhouse gas emissions by 30% in ten years -- which currently impact over half a billion square feet of space. Subsequently, Kerr conceived and launched the City Energy Project at the Natural Resources Defense Council, which is assisting ten major American cities – from Los Angeles to Chicago, Houston and Atlanta – in developing large-scale efficiency policies similar to New York. She is now the President of LK POLICY LAB.
