How the World Green Building Council Is Driving Net Zero Carbon Buildings
Exploring how the WGBC is pioneering global change in building sustainability through net zero carbon commitments.
World Green Building Council’s Net Zero Revolution
Buildings are front and center in the global response to climate change. Accounting for nearly 40% of energy-related CO2 emissions—including both the energy used to power buildings and the emissions locked into construction materials—transformation in this sector is essential. The World Green Building Council (WGBC) leads a coalition driving the vision for a net zero carbon built environment, setting ambitious targets for industry, governments, and organizations worldwide.
Why Buildings Matter in Climate Action
The building and construction sector is not only responsible for almost 40% of global CO2 emissions, but is also on track to double in scale by 2060 if current trends continue. These emissions can be divided into:
- Operational emissions: From heating, cooling, lighting, and powering building activities.
- Embodied emissions: From the manufacturing and transport of materials, construction processes, repairs, and demolition.
This sector also consumes about half the world’s resources, making rapid decarbonization both a challenge and an opportunity for climate mitigation and economic innovation.
WGBC’s Net Zero Carbon Buildings Commitment
In 2018, the Net Zero Carbon Buildings Commitment was launched by the World Green Building Council. This landmark initiative challenges businesses, cities, states, and organizations to:
- Achieve net-zero operational emissions within all buildings they own, occupy, or develop by 2030.
- Advocate for all buildings worldwide to meet net-zero standards by 2050.
- Address embodied carbon in new buildings and major refurbishments.
- Adopt a disclose, reduce, and offset strategy for all carbon emissions.
Table: WGBC Commitment Objectives
| Focus Area | Objective |
|---|---|
| Operational emissions | Reduce energy demand and use 100% renewable energy by 2030 |
| Embodied carbon | Measure and reduce upfront emissions for new builds and major refurbishments by 2030 |
| Global advocacy | Promote whole-life carbon policies and encourage zero-carbon building codes worldwide |
| Market transformation | Drive green finance, benchmarking, and wider stakeholder alignment |
Mechanisms for Transformation: How WGBC Drives Change
The Council fosters transformation through a multi-pronged approach involving voluntary leadership, regulatory reform, and market tools:
- Net Zero Carbon Buildings Commitment: Endorsed by over 180 businesses, cities, and organizations, covering 7 million square meters of global building space.
- Advancing Net Zero Program: Supports national Green Building Councils in launching certification, carbon accounting, and verification systems tailored to local needs.
- Whole Life Carbon Vision: Advocates measuring emissions across the entire lifecycle of buildings—from material extraction to demolition and reuse.
- Collaborative Models: Engages stakeholders from finance, policy, building operations, and materials sectors, supporting region-specific solutions and market transformation.
The Scope: Whole Life Carbon Approach
Climate leadership now requires more than energy efficiency—it demands a whole life carbon perspective. This means:
- Operational emissions must be slashed through efficiency and renewable energy.
- Embodied carbon—especially in new builds—must be minimized by shifting to low-carbon materials, recycling, and design for disassembly.
- Offsetting, where unavoidable emissions remain, must follow best-practice principles and be traceable, additional, and credible.
What others are reading
This whole-system transformation is vital as buildings’ impact spans construction, operation, repair, and end-of-life phases. The WGBC’s approach prioritizes carbon reduction first, using offsets only as a last resort.
How the Commitment Works
Signatories to the Commitment are diverse—ranging from multinational corporations to local governments and non-profits. All must:
- Commit to net zero operational carbon in their portfolios by 2030.
- Address embodied carbon in new developments and major refurbishments.
- Disclose and track carbon reductions annually, publicly reporting progress.
- Show leadership by advocating for stronger policy frameworks, market incentives, and industry transformation.
Global Momentum: Uptake and Leadership by Region
Progress varies across regions, with some countries leading in the adoption and implementation of green building codes:
| Region | Commitments (2023) | 2030 Target | Key Green Building Councils |
|---|---|---|---|
| Europe | 450 | 1,500 | UK, Germany, France, Nordics |
| North America | 300 | 1,000 | U.S. Green Building Council, Canada |
| Asia Pacific | 200 | 800 | Australia, Singapore, South Korea |
| Latin America | 120 | 400 | Colombia, Mexico, Brazil |
| Africa | 80 | 300 | South Africa, Kenya, Nigeria |
While adoption is still in early stages in many developing markets, ambitious regional Green Building Councils are creating new policy pathways and technical guidance to accelerate net zero transitions globally.
Business Opportunities and Co-benefits
Transitioning the built environment offers wide-ranging advantages, including:
- New green jobs in construction, materials innovation, design, and technology.
- Lower energy bills and increased resilience for occupants and property owners.
- Enhanced asset value as demand grows for environmentally responsible real estate.
- Alignment with global investor expectations for climate-aligned portfolios.
- Improved health and productivity, as better buildings mean healthier air and more comfortable spaces.
Governments and investors are increasingly recognizing these benefits, integrating net zero requirements into building codes and financing strategies worldwide.
Challenges Ahead: Fragmentation and Roadblocks
Despite progress, the path to a net zero building stock is not without obstacles:
- Fragmented value chains mean coordination between material producers, builders, real estate developers, and owners is complex.
- Regional disparities in policy ambition and technical capacity persist.
- Verification and reporting standards for carbon reductions vary, complicating benchmarking and accountability.
- Embodied carbon remains hard to track and mitigate, especially in rapidly growing economies.
Programmes like Advancing Net Zero and collaborations with initiatives such as the We Mean Business Coalition and World Resources Institute aim to address these issues by promoting best practices and harmonized frameworks internationally.
The Role of Policy, Advocacy, and Market Transformation
Market transformation on a global scale requires regulatory, financial, and technical tools, such as:
- Strong national and local building codes mandating energy efficiency and renewable energy use.
- Green finance products, including sustainability-linked loans and real estate funds.
- Public sector leadership in adopting and promoting high standards for sustainability in public assets and infrastructure.
- Building materials innovation, including circular design principles, low-carbon concrete, and sustainable timber.
Policymakers are critical enablers, setting the rules, incentives, and market signals needed to accelerate uptake. The WGBC works with governments, businesses, and NGOs worldwide to mainstream these changes.
