Has the entity disclosed GHG emissions data of its portfolio?
Assessment Instructions
Intent: What is the purpose of this indicator?
Disclosure of GHG emissions facilitates investor carbon footprinting and enables efficient capital allocation to industries with low environmental impacts. Many countries have introduced or are considering mandatory GHG emissions reporting. Proactive property companies and REITs stay ahead of this trend.
Input: How do I complete this indicator?
Select yes or no. If yes, disclose where the online information can be found.
Terminology
Absolute data
An absolute consumption, emission or production measure provided by a firm regarding its emissions and use of waste, GHG, water or energy for the reporting year.
Disclosure
The act of making information or data readily accessible and available to all interested individuals and institutions. Disclosure does not need to be public, but must be external to the reporting entity and cannot be an internal and/or ad hoc communication within the participating entity.
GHG emissions
GHGs refers to the seven gases listed in the GHG Protocol Corporate Standard: carbon dioxide (CO2); methane (CH4); nitrous oxide (N2O); hydrofluorocarbons (HFCs); perfluorocarbons (PFCs); nitrogen trifluoride (NF3) and sulfur hexafluoride (SF6). They are expressed in CO2 equivalents (CO2e).
Intensity data
The amount of Energy/GHG Emissions/Water/Waste used or produced per unit of an appropriate denominator, including but not limited to: floor area and persons.
Like-for-like data
A metric that enables comparison of results between years whilst controlling for changes such as expansions and acquisitions of the portfolio that could over or understate the values of one year as compared to another.
Portfolio data Coverage
Information about the part of the portfolio for which the Energy/Water/GHG/Waste data is disclosed. This can be a percentage of floor area or number of assets covered, or a description (e.g., only consumption data from common areas is disclosed, or the consumption data relates to all directly managed assets).
Validation: What evidence is required?
Evidence: URL. Ensure that the hyperlink is not outdated and the relevant page is directly accessible. It is possible to provide multiple hyperlinks.
Absolute GHG data must be a measure given in a metric value and be comparable.
Like-for-Like data must state the use of the Like-for-Like methodology when calculating energy values.
Intensity data should be recorded using a clear, appropriate denominator.
Portfolio Coverage points can only be awarded if a clear percentage of the floor area or number of assets covered by the GHG value is stated.
Best practice GHG disclosures are aligned with the GHG Protocol and provide a clear description on the methodology used. Emissions are broken down into Scope I, Scope II (location-based) Scope II (market-based), and Scope III. In addition, emissions are per property type and/or location, and clearly indicate for which areas data is disclosed/available (tenant spaces, common areas, base building).
Scoring
Scoring: How does GRESB score this indicator?
Points are awarded to each selected checkbox option and are then aggregated to calculate the indicator’s final score.
It is not necessary to select all answer options in order to obtain the maximum score for this question.
