Consultation for the ACT Buildings Sector Methodology

Accounting for 34% of total emissions in 2023, the construction and operation of buildings continue to be a major source of global CO₂ emissions today. Aligning with the Net Zero Emissions Scenario requires the buildings sector’s energy intensity to decrease at a rate nearly five times faster over the next decade than it did during the previous one. Thus, this decade is pivotal for implementing the measures required to achieve the targets of all new buildings and 20% of the existing building stock to be zero-carbon-ready by 2030. There is a great opportunity, as global modelled scenarios indicate that, with ambitious policies combining sufficiency, efficiency, renewable energy coupled with the removal of decarbonization barriers, retrofitted existing buildings and new buildings could approach net-zero GHG emissions by 2050.

ACT Buildings Methodology consultation

WBA, together with ACT, is launching this extensively revised ACT Buildings Methodology, which consolidates three separate methodologies into a single streamlined framework. The new approach is designed to cover the majority of the construction, property development, and real estate value chain under a unified methodology.

The public consultation will run from 29 June to 29 July 2026, giving companies and wider stakeholders the opportunity to provide feedback on the methodology's completeness and key methodological choices. Feedback provided will inform the final publication of the methodology planned for end of 2026.

Who is this consultation for:

• Companies operating across the building construction, property development, and real estate value chain
• Institutions focused on evaluating companies' transition readiness and climate transition plans
• Financial institutions seeking a deeper understanding of the climate performance of the companies they finance

• Initiatives working to hold companies accountable for their climate commitments
