Global Coalition Formed to Standardise Sustainable Building Materials Assessment

A group of major sustainable building and materials organisations has announced a new global partnership designed to align how building products and materials are assessed for sustainability across the built environment. The partnership brings together Building Research Establishment (BRE), the Green Building Council of Australia (GBCA), mindful MATERIALS, International Living Future Institute (ILFI), International WELL Building Institute (IWBI), and the U.S. Green Building Council (USGBC).

These organisations aim to establish common metrics, data, and language for evaluating the sustainability of construction materials. The goal is to streamline processes across rating systems, reduce duplication, and create greater clarity for the industry.

Tackling Fragmentation in the Materials Sector

Construction remains one of the largest consumers of raw materials worldwide. Yet, the frameworks used to assess sustainability vary widely across regions and certification bodies. This fragmentation leads to duplication of work, inconsistent requirements, and higher compliance costs for manufacturers and developers.

By addressing these inconsistencies, the new partnership seeks to align assessment criteria, simplify data management, and promote transparency across the global building materials supply chain. The initiative focuses on three key objectives:

• Creating a common language for material sustainability assessment

• Aligning data and metrics across certification tools

• Establishing shared global targets for climate impact, nature protection, and circularity

Benefits for Manufacturers and Project Teams

For manufacturers, this alignment promises a more efficient reporting process. Standardising how product data is collected and recognised could reduce the cost of compliance and make it easier to bring sustainable products to market.

For architects, designers, and specifiers, a harmonised system means clearer access to verified sustainability information and easier comparison between products. Building owners and investors also stand to benefit through simplified alignment with corporate sustainability commitments and disclosure requirements.

As more regulations require environmental and social transparency, such as climate and nature-related financial disclosures, having unified assessment standards will become essential to remain compliant and competitive.

Partnership Roadmap and Next Steps

The initiative is currently in its early stages. Its first deliverable will be a public “call to action” outlining shared goals and raising awareness of the challenges posed by fragmented assessment systems.

Following that, a detailed “principles and metrics” paper is planned for 2026. This document will propose specific technical and operational pathways for integrating aligned criteria into major global rating tools, including:

• BREEAM (administered by BRE)

• Green Star (administered by GBCA)

• LEED (administered by USGBC)

• Living Building Challenge (administered by ILFI)

• WELL (administered by IWBI)

The partnership emphasises that regional diversity will be respected, recognising that local markets and supply chains operate under different environmental and regulatory conditions.

Impact on Net-Zero and Circular Economy Goals

The built environment contributes significantly to global resource use and carbon emissions. Estimates suggest that construction accounts for more than half of the world’s raw-material extraction. Harmonising how materials are assessed could accelerate the adoption of circular and low-carbon practices, such as recycled content, reuse, and reduction of embodied emissions.

By improving clarity and trust in sustainability data, the partnership aims to make it easier for companies to select and scale environmentally responsible products. It may also help reduce costs and expand access to global markets for sustainable materials.

For developers and asset managers working toward net-zero targets, the initiative provides a pathway to integrate materials performance into carbon-reduction strategies and procurement policies.

Challenges and Implementation Considerations

Achieving alignment across multiple certification systems is complex. Each framework has evolved differently, reflecting regional priorities, available materials, and policy contexts. Aligning them will require detailed collaboration between technical experts, industry representatives, and certification administrators.

Manufacturers may need to update their data-reporting systems, specifiers will need guidance on interpreting aligned criteria, and certification bodies will need to adapt their tools. Despite these challenges, the potential benefits, simplified compliance, improved data reliability, and faster progress toward sustainable construction are widely recognised.

Relevance for the Net-Zero Transition

For professionals engaged in sustainable construction, material manufacturing, and ESG reporting, this initiative marks a significant step toward global consistency. As the sector works to lower embodied carbon and embed circularity, having clear and comparable sustainability criteria will be essential.

The partnership’s success could reduce bottlenecks caused by fragmented data, improve confidence in product claims, and accelerate the global shift toward low-impact, high-performance materials. It represents a crucial move toward harmonising sustainability in one of the world’s most resource-intensive industries.
