Established at COP21, the Global Alliance for Buildings and Construction (GlobalABC) brings together more than 400 national governments, businesses, associations and academic institutions, is hosted by the United Nations Environment Programme (UNEP), and serves as the leading global platform bringing together all stakeholders in the sector around a shared vision: to make the buildings and construction sector carbon-neutral, efficient and resilient.
The OID is a member of GlobalABC and has been coordinating the activities of its Adaptation Hub since 2018. The OID has also been a elected to the GlobalABC Steering Committee since 2025.
GlobalABC acts as a leading international platform and a catalyst for action to transform the buildings and construction sector towards carbon neutrality and resilience. It mobilises public and private stakeholders worldwide, promotes the sector’s key role in climate action at international events (notably the COPs), and coordinates transformative initiatives such as the Buildings Breakthrough. It tracks the sector’s progress through benchmark tools and reports such as the Global Status Report on Buildings, whilst contributing to the definition of targets for 2030 and 2050. GlobalABC also supports countries in developing roadmaps tailored to their specific contexts, and supports the private sector’s transition towards low-carbon and resilient economic models, notably through its initiatives dedicated to market transformation and financing.
Since 2025, the OID has been a member of the GlobalABC steering committee.
Coordinated by the OID, this initiative aims at bringing together all public and private stakeholders across the building and construction value chain around a common goal: to strengthen the resilience of the built environment. As a platform for collaboration and advocacy, it promotes science-based adaptation strategies, supporting the shift from a historical approach to risk to a framework based on climate projections. Since 2018, the Hub has structured its work around key publications, whilst drawing on feedback and existing methodologies. In particular, it develops concrete adaptation pathways, tailored to each type of stakeholder, in order to propose short-, medium- and long-term actions and to remove systemic barriers. This work has been directly inspired the adaptation charter championed by the OID.
