The Global Alliance for Building and Construction (GABC) has created this guide to address the urgent need for further extending the scope and ambition of building sector actions in Nationally Determined Contributions (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 NDCs. It focuses 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 scale for integration of distributed renewable energy supply.
This guide is structured around three stages for incorporating such ambitious and effective buildings sector GHG mitigation actions into NDCs; Mapping, Prioritizing and Implementing & Monitoring. Each section focuses on how to achieve ambitious and effective outcomes in the buildings sector. You can dive into the guide at any point depending on your own circumstances. It also links with the evidence base on building sector actions, tools and resources offered by Global ABC member organisations.
