From Assessment to Action: A Spotlight on Whole Life Carbon Processes in Cities

Cities are at the forefront of climate action in the built environment. As global efforts to decarbonize buildings accelerate, the ability to measure, compare and strengthen whole life carbon (WLC) processes at the city level is becoming a critical enabler of meaningful progress. While whole life carbon approaches are gaining traction worldwide, their implementation remains uneven – creating fragmentation, uncertainty for industry, and missed opportunities to scale impact.​

This white paper introduces a criteria-based assessment framework that brings clarity to how cities are translating ambition into action. By systematically assessing policies and initiatives that drive whole life carbon processes – from definition and transparency through to performance floors and incentives – the framework enables consistent comparison across cities, highlights leading practices, and identifies gaps where further action is needed.​

Applying the framework to six cities across different regions – Bogotá, Cape Town, London, New York, Paris and Shanghai – the white paper reveals both encouraging progress and persistent challenges. While most cities have established operational energy and carbon requirements, progress on embodied and whole life carbon remains more fragmented. The case studies show how city-level leadership can act as a powerful test bed for innovation, build confidence for wider adoption, and help align public and private action across the built environment value chain.​

By strengthening consistency and comparability in WLC implementation, this work supports the public-private ambition loop at the heart of WBCSD’s Market Transformation Action Agenda. It equips policymakers, cities and businesses with a shared language and practical tool to accelerate uptake of whole life carbon processes, steer investment toward low‑carbon solutions, and ultimately drive faster, more coordinated decarbonization of the built environment.​

What’s next?​
The framework is designed to be scalable and adaptable. WBCSD and partners will expand its application to additional cities, refine it through stakeholder engagement, and update it over time to track progress. For business, this creates clearer signals on policy direction, reduces uncertainty across markets, supports more comparable investment decisions, and helps companies anticipate and align with emerging WLC requirements – unlocking opportunities to scale low‑carbon solutions and reward innovation.​
