Zero Carbon Building Accelerator
Helping cities reduce building emissions to meet climate goals.
Building construction and operations are among the largest contributors to climate change, accounting for nearly 40% of energy-related CO2 emissions globally. The global building stock is set to double by 2060 due to population growth and urbanization, which could further contribute to a warming world. Without dramatic energy efficiency improvements and energy decarbonization, projected energy demand from buildings will continue to drive massive absolute increases in carbon emissions.
Paradoxically, buildings are also the biggest, most cost-effective climate mitigation solution available. Every $1 invested in efficiency saves $2 in new electricity generation and distribution costs. Despite their extraordinary potential, 80% of economically viable energy savings in buildings remain untapped. To meet carbon reduction and resilience goals, the world’s building stock must reach net zero by 2050.
The Zero Carbon Building Accelerator builds on WRI’s success with the Building Efficiency Accelerator (BEA) to bring new ambition and build on the lessons, expertise and resources of the BEA with a broader mandate to support decarbonizing the world’s buildings by 2050.
WRI is helping governments eliminate build sector emissions by facilitating the development of new solutions, peer learning, policy alignment and more.
The Zero Carbon Building Accelerator helps governments eliminate building sector CO2 emissions through five strategies:
1. Dialogue: We explore how to achieve zero carbon building commitments through facilitated policy dialogues with national and local governments, utilities, the private sector and civil society.
2. Assess: We analyze the social, environmental and economic costs and benefits of zero carbon building policies and investments to inform local government decisions.
3. Act: We work closely with national and local governments to develop and adopt policies and actions towards building decarbonization.
4. Monitor: We test and share innovative methods for monitoring progress at the national and local levels.
5. Invest: We develop business models for investing in zero carbon buildings with multilateral, national and local banks and in consultation with the private sector.
Scaling Up Impact
At the subnational level, the Zero Carbon Building Accelerator and participating ministries have engaged jurisdictions in Colombia, Costa Rica, India, Kenya and Turkey to develop and implement action plans that build on existing city goals and priorities.
Working in consultation with diverse stakeholders, WRI also provides a global forum to explore common challenges and opportunities related to building decarbonization. For example, informal housing may bring specific decarbonization challenges and require different pathways than institutional and commercial buildings. Project partners also work with regional development banks and financial institutions to pursue new business models and financial solutions to support building decarbonization.
Lessons learned in developing roadmaps, action plans, policies and programs at the national and subnational level will inform scalable, replicable pathways for ambitious climate action in the building sector.

In this closing webinar for the Zero Carbon Building Accelerator, global thought leaders spoke about their experiences in developing national roadmaps and aligned city action plans for building sector decarbonization and what kind of business models and tracking systems may speed their implementation.
