OECD Report Highlights Need for Whole Life-Cycle Approach to Achieve Zero-Carbon Buildings

Buildings account for 40% of global energy consumption and nearly one-third of global greenhouse gas (GHG) emissions. To meet global climate targets, addressing both operational and embodied carbon emissions is crucial. If left unaddressed, embodied emissions could contribute up to 50% of the total carbon footprint of new buildings by 2050.

The OECD has released a report titled "Zero-Carbon Buildings in Cities – A Whole Life-Cycle Approach," which provides best practices, proven strategies, and actionable insights for policymakers to accelerate the transition to zero-carbon buildings.

Key Policy Recommendations:

1. Whole Life-Cycle Approach – Shift the focus from operational carbon to also include energy efficiency and embodied carbon.
2. Step-by-Step Implementation – Gradual adoption of whole life carbon policies to ensure feasibility.
3. Data & Digital Tools – Improve data collection and use digital solutions to streamline processes.
4. Vertical Coordination – Strengthen city-led initiatives through better coordination with national and regional policies.
5. Public-Private Partnerships – Encourage collaboration between government, industry, and academia for sustainable building solutions.

The report underscores the need for comprehensive policies that go beyond energy efficiency and operational emissions, ensuring that buildings contribute to a sustainable, low-carbon future.
