Ben Feldman, Managing Director (Washington, D.C.), manages climate change and renewable energy research and analysis for Natsource, and will direct regulatory affairs and analysis for the company’s Greenhouse Gas Credit Aggregation Pool (GG-CAP).  Prior to joining Natsource, Mr. Feldman served as Director of Environmental Services at the Environmental Resources Trust (ERT), where he oversaw the development, management, and operation of ERT’s GHG RegistrySM, a system for tracking and recording GHG emissions and emissions reductions.  Prior to ERT, Mr. Feldman worked on energy and environmental policy issues as a Senior Associate at ICF Consulting.  At ICF, Mr. Feldman worked extensively with private sector clients, multinational institutions, and governments on electricity and natural gas markets, energy efficiency and air emissions, emissions accounting, auditing standards, and measurement and verification protocol development.  This work included participation in the audit of BP’s GHG program and the development of the measurement and verification protocol used by the World Bank’s Prototype Carbon Fund (PCF) to monitor emissions performance from the Liepaja, Latvia landfill gas project.  The methodology used to monitor this project formed the basis for one of the Clean Development Mechanism (CDM) Executive Board’s approved methodologies for CDM projects.  Mr. Feldman has a BA degree in history from the University of Rochester and an MA in international affairs from the George Washington University.
