A guide for incorporating Buildings Actions in NDCs

The buildings sector contributes nearly 40% to global energy-related annual GHG emissions (IEA/UNEP, 2018). Final energy demand from buildings is predicted to increase 50% by 2050 compared with 2015 levels under business as usual scenarios due to rapid urbanisation and the doubling of the built surface area.

A new guide written for the UN Environment Program and the Global Alliance for Buildings & Construction is designed to address the urgent need for further extending the scope and ambition of building sector actions in NDCs, the opportunities for aligning with commitments made by non-party actors, and the renewed support for successively increasing ambition and implementing actions of NDCs. It provides a simple process for incorporating or updating ambitious and effective building sector actions in Nationally Determined Contributions. The guide focusses particularly on key actions that are necessary to address and overcome common challenges faced by countries in designing, financing and implementing ambitious and effective actions, and is intended to support the progressive updating of NDCs.


  • Building from existing policies and commitments, countries can extend the ambition of building sector actions by:
  • Increasing the scope of existing building energy regulations to include a greater proportion of building types, particularly housing, and to renovation projects;
  • Increasing energy performance standards for building envelopes, heating, cooling and ventilation systems, and appliances;
  • Integrate building sector actions with urban land-use planning to enable the decarbonisation opportunities of sustainable mobility choices, reducing urban heat-island effects, and providing scalefor integration of distributed renewable energy supply.
