About the GlobalABC Sufficiency Hub
The GlobalABC Sufficiency Hub endeavors to highlight the pivotal role of sufficiency in significantly reducing carbon emissions in the buildings sector. Its mission includes sharing best practices, formulating actionable recommendations, and supporting the operationalization of sufficiency.
Relying solely on efficiency techniques, metrics, and data to meet our 2030/2050 decarbonization targets is not enough, as efficiency gains alone risk being offset by the rebound effect. Therefore, integrating sufficiency measures first is essential to maximize the effectiveness of other strategies (efficiency improvements and renewable energy solutions), prevent rebound effects, and accelerate emissions reductions as needed.
Sufficiency has now gained prominence in transition scenarios outlined by influential bodies such as the Intergovernmental Panel on Climate Change and the International Energy Agency. Given that buildings contribute to 37% of global energy and process-related emissions, sufficiency measures are indispensable to achieving the Paris Agreement goals of halving sector emissions by 2030.
In pursuit of implementing sufficiency worldwide, the Sufficiency Action Group brings together professionals from diverse backgrounds within the buildings industry. The Action Group aims to foster a shared understanding of sufficiency and to explore how it can be implemented in a context-sensitive manner, acknowledging that solutions must be adapted to diverse local realities. The shared goal remains clear: ensuring that everyone's needs are met in terms of energy, materials, land, and water, while respecting the constraints of our planet's limits.
The Hub is engaged in the Buildings Breakthrough Priority Action Area B1 — Standards and Certifications.

Activities
The hub aims at recognizing, at a global level, sufficiency as a necessary decarbonization lever - and above all - as a lever to keep the sector within the 9 planetary boundaries – if considered first and well-combined to efficiency and green-sourced energy and materials.
The Sufficiency Hub pursues several workstreams to advance sufficiency as a global decarbonisation lever in the buildings sector.
•Promoting "Sufficiency First" through tools and resources to inspire future actions in line with sufficiency.
•Developing key metrics to operationalize sufficiency trajectories.
•Creating policy guidance to support the integration of sufficiency measures in the buildings sector.
•Shifting narratives through communication by demonstrating that sufficiency is feasible and accessible and brings many desirable benefits by improving people's lives and well-being.
Events
The Sufficiency Action Hub participated in COP30 at the Buildings and Cooling Pavilion. The Hub will host three webinars in 2026, each timed to coincide with the release of new deliverables.
