Asset-Specific Scoring

Understand scoring methodology specific to the Infrastructure Asset Assessment.

Materiality-Based Scoring

GRESB uses materiality‑based scoring across the Asset Assessment. This process ensures that all assets are assessed and scored based on the sustainability issues that are most material to their circumstances. It also reduces the reporting burden by removing the need to report on issues with little to no material significance to the participant.

Materiality Factors and Sustainability Issues

The GRESB Materiality Assessment (indicator RC7), along with additional information derived from the Entity & Reporting Characteristics indicators (RC2, RC3, RC4, and RC5), determine the relevance of 46 sustainability issues across the assessment. Each issue’s relevance level then determines its scoring weight.

An asset’s sustainability issue weightings are displayed at the bottom of the indicator in the GRESB Portal.

Materiality	Weighting
No relevance	0
Low relevance	0
Medium relevance	1
High relevance	2

Issues of ‘no’ or ‘low’ relevance are deemed non-material and receive no score in the assessment and are effectively removed from consideration. Issues of ‘medium’ and ‘high’ relevance are scored proportionally, with weights of one and two, respectively.

• For example, for entities in the primary sector ‘Renewable power: Solar power generation,’ the issue ‘Air pollution’ is of ‘No relevance’ and does not need to be considered by entities in this sector in the Assessment.

• On the other hand, for entities in the primary sector ‘Power generation x-Renewables: Independent Power Producers: Gas-Fired Power Generation’, ‘Air pollution’ is of ‘High relevance’ and will have a greater scoring impact across the assessment.

Once each of the sustainability issues has been assigned a materiality weighting (relevance), these apply to specific indicators in both the Management and Performance Components in slightly different ways.

• Management Component Materiality: Materiality influences two Aspects in the Management Component: Risk Management and Policies. Within these indicators, each sub-option (i.e., ‘Child labor’ or ‘Community development’ in PO2) is associated with a materiality/relevance level of 0, 1, or 2.

• Performance Component Materiality: Materiality influences all scored Aspects in the Performance Component. Each indicator is directly tied to an ESG issue; as such, the materiality weighting of 0, 1, or 2 applies to its entire maximum score. This means that the weight of each indicator within the Performance Component and overall GRESB Score is redistributed so that the component retains its overall 60% weight within the Asset Assessment.

Materiality and Scoring Tool

Participants can model an entity’s materiality results and their scoring implications using the Materiality and Scoring Tool. This tool, which models the GRESB Materiality Assessment of indicator RC7, contains the following information:

• Each indicator’s E, S, and G designation

• Each indicator’s default maximum score

• Each indicator's maximum score, once materiality is applied

• Each indicator’s weight in its respective Aspect and Component

• Details on how the materiality weightings are assigned based on materiality factor responses

• Sector definitions and sector-specific output metrics

Performance Tables

Most performance indicators (i.e., EN1, GH1, AP1) require participants to input quantitative data into a table. For these indicators, scoring depends on the values entered in specific cells. Scored cells are shaded to indicate their scoring impact. For details on which cells are scored and how, please refer to the indicator-specific requirements in the Completing GRESB Assessments page.

GRESB uses materiality‑based scoring across the Asset Assessment. This process ensures that all assets are assessed and scored based on the sustainability-related issues that are most material to their circumstances. It also reduces the reporting burden by removing the need to report on issues with little to no material significance to the participant.
