CLASP's role as a major force in proliferating energy efficiency standards and labels worldwide entails forming partnerships with governments and NGOs to give technical assistance to individual countries and regions. CLASP associates provide market analysis and research for baseline studies as well as monitoring and evaluation of program impacts.
USAID funding for CLASP has expanded so that the organization is currently playing a key role in the agency's South Asia Regional Initiative (SARI) energy program. CLASP has also joined with the U.S. Department of Energy for the Efficient Energy and Sustainable Development (EESD) partnership, which is the energy-efficiency component of America's energy commitment to the World Summit on Sustainable Development. In addition, CLASP helps Asian Pacific Economic Cooperation (APEC) provide access to codes and standards information through a web-based information network called the Energy Standards Information System (ESIS).
