JOIN the Building Efficiency Accelerator (BEA)

Join the BEA and double the rate of energy efficiency improvements by 2030 in the building sector in your city, town or region.

More than one-third of global energy demand is attributed to buildings – and cities contribute substantially to greenhouse gas emissions released that negatively impact on global climate change. By highlighting local leadership and action on buildings and sustainable energy, we can show that the transition to low carbon buildings is already well underway.

Visit the BEA website for more information. 

About the Building Efficiency Accelerator

In September 2011, former United Secretary-General Ban Ki-moon launched Sustainable Energy for All (SE4ALL) as a global initiative to mobilize action in support of three interlinked objectives:

  • Provide universal access to modern energy services.
  • Double the global rate of improvement in energy efficiency.
  • Double the share of renewable energy in the global energy mix.

As part of the strategy to double the rate of efficiency improvements, the Building Efficiency Accelerator supports public commitments at the city, regional and national levels.

The BEA collaborative network is led by the World Resources Institute, with ICLEI engaging to support local and subnational governments, together with 70 businesses, governments and non-governmental organization. It provides tools, expertise and technical capabilities to subnational governments, who commit to implementing and reporting on measures designed to improve efficiency. Reporting takes place in the carbonn Climate Registry.

ICLEI focuses on the development of guidance, capacity building and offering tailored support to local and subnational governments to assess priorities, implement and track actions, and exchange lessons learned. ICLEI is also a lead partner in the closely related District Energy in Cities Initiative, led by UN Environment, working to interlink available guidance and opportunities for peer exchange.



Join today

To join the BEA each local government commits to:

  • Enact or update an existing policy or demonstration project.
  • Undertake an efficiency project or program. 
  • Set a baseline, report and communicate action and annual progress against goals, and share experience with other governments.

For more information about becoming involved in the BEA as a city or an organization, please see our Letter of Invitation to the BEA and introductory materials. To learn more about what being a partner city entails or to formally become a partner, please see the BEA Partnership Agreement, the SE4ALL Statement of Intent or the Statement of Support for businesses and NGOs (WRI). For additional information on how your local government can join the BEA, kindly contact







The reporting platform

The carbonn Climate Registry (cCR) is a recognized reporting platform for local governments joining the Building Efficiency Accelerator. 

The cCR is open for voluntary reporting to all levels of governments, from towns and cities to states, regions and provinces. The cCR has been designed to support and facilitate vertical integration, encouraging local governments within the same geographic region to report, also ensuring that data is not double-counted when aggregated.

The cCR is managed by the Bonn Center for Local Climate Action and Reporting - the carbonn Center - based in Bonn, Germany, hosted by the ICLEI World Secretariat.
