IEA Technology Collaboration Programme on Energy Efficient End-Use Equipment (4E)

Thirteen countries from the Asia-Pacific, Europe and North America have joined together under the forum of 4E to share information and transfer experience in order to support good policy development in the field of energy efficient appliances and equipment.

They recognise the huge benefits for energy security, economic development and greenhouse gas abatement from maximising the use of energy efficiency to meet future energy demand.

4E focuses on appliances and equipment since this is one of the largest and most rapidly expanding areas of energy consumption. With the growth in global trade in these products, 4E members find that pooling expertise is not only an efficient use of available funds, but results in outcomes that are far more comprehensive and authoritative.

However, 4E does more than sharing information - it also initiates projects designed to meet the policy needs of participants, enabling better informed policy making. The main collaborative research and development activities can be found by following the links to 4E Annexes and Projects.

Launched in 2008, in view of it's achievements during the first five-year term, the IEA endorsed 4E's application for a second term that will run to 2019.  The new Strategic Plan (2014-19) is available for download under the Scope and Objectives link on this page. 

All countries are welcome to join 4E.  See the FAQ on this page for more details. 


4E activities are determined solely by its members, which are represented by ministries, departments or agencies responsible for national government energy efficiency policies.  This structure ensures that the work of 4E is tied to the policy requirements of governments, and that the outputs have a tangible impact on their policies.

The detailed achievements in all areas of 4E work are identified in the 4E Annual Reports available on this website.  Key achievements cited by 4E members include:

  • The platform provided by 4E has given member governments a deeper understanding of the current and future priorities for energy efficiency policies within each country, which they use as a basis for making informed choices about national policy options.
  • The 4E platform promotes knowledge sharing, and equally importantly, develops contact amongst peers which engenders on-going communication beyond the 4E environment.
  • 4E’s reports have enabled 4E countries to compare the performance of locally available products against those in the rest of the world and to identify global trends in different technology areas. These have assisted governments to set national policy priorities.
  • 4E has developed best practice methodologies for building national scenarios, as well as the collection and analysis of data. These have helped governments to improve their evaluation of national program impacts.
  • 4E provides a forum for governments to explore opportunities for research or policy development collaboration on specific products through multi-lateral or bi-lateral arrangements.
  • 4E projects have supported national capacity building in high quality accredited testing laboratories for appliances and equipment.
  • 4E has provided governments with representation at international appliance standards forums, making these more relevant to the needs of policy makers.
  • The outputs of 4E have provided tangible evidence of the benefits of energy efficiency and assisted members to reinforce the rationale for their own program renewal and boost the allocation of resources.
Since 2008 4E published over 430 individual reports, policy briefs and newsletters.  4E has also participated in nearly 300 workshops and exchanges of technical or policy information to government officials and industry.
