In 1999 Berkeley Lab, the Alliance to Save Energy the, and International Institute for Energy Conservation formed a strategic alliance that resulted in the formation of the Collaborative Labeling and Appliance Standards Program. CLASP promotes efficiency standards and product energy-efficiency labels in developing and transitional countries through partnerships with agencies, stakeholders, and other institutions in those countries.

It brings together resources and project teams from diverse organizations, provides them with technical support, and oversees and provides quality control for efficiency standards and labeling efforts around the world. It is supported by a roster of international agencies, including the: U.S Agency for International Development, United Nations (UN) Foundation, Energy Foundation, U.S. DOE, U.S. Environmental Protection Agency, U.S. Department of State, UN Development Program Global Environmental Facility, World Bank, and Australian Greenhouse Office, among others.

CLASP projects enhance the capability of a country's institutions to:

  • implement and manage standards programs,
  • increase production of energy-efficient products by manufacturers,
  • improve the average energy efficiency of appliances and equipment,
  • significantly reduce electricity consumption, and
  • lower emissions of greenhouse gases and other pollutants.

The Collaborative has assisted development and implementation of 10 new minimum energy-performance standards and 12 different types of product energy-efficiency labels in countries including China, Ghana, India, and Tunisia. By the year 2014, savings from these standards and labels are estimated to reach above 200 terawatt hours (TWh), and 250 megatons of avoided carbon dioxide (CO2) emissions (70 megatonnes of carbon).

The organization's two prominent global tools are its website (, and its guidebook, Energy-Efficiency Labels and Standards: A Guidebook for Appliances, Equipment, and Lighting, Second Edition.

CLASP is a registered sustainable development partnership with the World Summit on Sustainable Development and part of U.S. DOE's Efficient Energy for Sustainable Development partnership, which is the energy-efficiency component of the U.S. commitment to climate change.
