Sustainability Strategy

Strategy which (1) sets out the participant’s procedures and (2) sets the direction and guidance for the entity’s implementation of sustainability measures.

No evidence required.

The scoring of this indicator is equal to the sum of the fractions assigned to the selected options and respective sub-options, multiplied by the total score of the indicator.

This indicator examines whether the entity has specified sustainability requirements for materials used in construction, including the scope of materials covered. Establishing such requirements supports improved transparency on material impacts and helps identify opportunities to reduce embodied carbon and other environmental impacts.

Select ‘Yes’ or ‘No’. If 'Yes', select all applicable sub-options.

• If the entity uses Life Cycle Assessments (LCAs), it should indicate which building components are typically included within the LCA scope, as well as which lifecycle phases are covered.

  • This should include LCAs conducted for new construction projects, as well as for retrofits and renovations.

• Other: State the other materials to which the requirements apply. Ensure that the other answer provided is not a duplicate of the selected option above.

Terminology

Envelope

The envelope is the outer elements of a building, including walls, windows, roofs, and floors, including those in contact with earth.

Lifecycle assessment (LCA)

A comprehensive methodology for evaluating the environmental impacts of a product, process, or service throughout its entire life cycle, from raw material extraction through manufacturing, use, and end-of-life disposal or recycling. It quantifies resource consumption, emissions, and other environmental effects across all stages, providing a holistic view that helps identify opportunities for improvement and supports informed decision-making in product design and sustainability strategies.

Modules A1-A3

A1-A3 (also referred to as ‘cradle to gate’) cover the carbon emissions released during extraction, processing, manufacture (including prefabrication of components or elements) and transportation of materials between these processes, until the product leaves the factory gates to be taken to site. Note that biogenic carbon sequestered in the products used should not be included in the assessment of the upfront carbon. 

Module A4

A4 covers the carbon emissions released from the transport of materials or products from the factory gate to the construction site. 

Module A5

A5 covers carbon emissions due to activities on site (site huts, machinery use etc.) and the production, transportation and end of life processing of materials wasted on site. 

Sustainability Attributes (materials)

Evidence

The evidence provided will be subject to manual validation.

The evidence should support each of the selected issues. The evidence must demonstrate that the entity has defined sustainability-related requirements for materials, such as embodied carbon, recycled content, responsible sourcing, environmental certifications, or similar material attributes.

Other Answer

The other answer(s) provided will be subject to manual validation.

State the specific material or building element for which the entity has specified sustainability-related requirements. Other answers cannot be a duplicate of a previously selected option. Multiple Other answers are acceptable, but only one will count toward the score.

The scoring of this indicator is equal to the fraction assigned to the selected option, multiplied by the total score of the indicator.

Evidence: For selections subject to manual validation, the validation status acts as a multiplier to determine that selection's final score.

If any requirements are not met, the evidence may not be accepted, depending on the level of alignment with the requirements.

Other: The 'Other' answer is manually validated and assigned a score, which is used as a multiplying factor, as per the table below:

​Scoring Basics

This indicator assesses whether the entity can measure and report embodied carbon for new development projects, including baseline and as-designed carbon intensity. Quantifying embodied carbon supports transparency and helps identify opportunities to reduce emissions associated with construction.

Select ‘Yes’ or ‘No’. If 'Yes', select all applicable sub-options.

• Selecting 'Yes' to the indicator will require reporting a value for at least the required metrics (average baseline carbon intensity and as-designed embodied carbon for new development data centers).

  • The entity should select the requirements that it uses in its procurement and purchasing processes. This should include materials used for new construction as well as renovations and retrofits.

Terminology

As-designed Embodied Carbon

The estimated embodied carbon of a project based on its final design specifications prior to construction.

Baseline Embodied Carbon

A reference scenario representing typical or business-as-usual embodied carbon performance against which improvements can be measured.

Carbon intensity

The amount of greenhouse gas emissions expressed per unit of output.

Embodied Carbon

Refers to the total greenhouse gas emissions associated with the extraction, manufacturing, transportation, construction, and end-of-life disposal of building materials and products, excluding operational emissions. It represents the carbon footprint "embedded" in materials before a project even begins operation.

Environmental Product Declaration (EPD)

A standardized, third-party verified document that transparently communicates the environmental impacts of a product throughout its life cycle, including information on carbon footprint, energy use, waste generation, and resource consumption. EPDs follow international standards (ISO 14025) and provide comparable, credible data that helps architects, designers, and purchasers make informed decisions about the environmental performance of building materials and other products.

Health Product Declaration

Products and materials for which the inventory of all ingredients used is publicly available, with a full disclosure of all known hazards and associated effects.

Rapidly Renewable Materials

Materials made from agricultural products that are typically harvested within a 10-year or shorter cycle, such as bamboo, wool, cotton insulation, Agrifiber, linoleum, wheatboard, strawboard and cork.

No evidence required.

The scoring of this indicator is equal to the sum of the fractions assigned to the selected options and respective sub-options, multiplied by the total score of the indicator.

GRESB, 2026. What is embodied carbon in the real estate sector and why does it matter? Link

This indicator assesses whether the entity includes sustainability best practices in construction requirements, including the scope of practices applied. Implementing such practices helps reduce environmental impacts during construction and supports more sustainable project delivery.

Select ‘Yes’ or ‘No’. If 'Yes', select all applicable sub-options.

Other: State the other typical construction requirements set by the entity. Ensure that the other answer provided is not a duplicate of the selected option above.

Terminology
