Assessment Instructions
Intent: What is the purpose of this indicator?
The intent of this indicator is to assess the entity’s measurement of water resource impacts. The inflow/withdrawal of water can have significant impacts on the environment and communities. Relatively high levels of water withdrawals can potentially create liabilities or regulatory risk.
Input: How do I complete this indicator?
Select Yes or No: If yes, complete the performance table and sub-questions.
Performance Tables
Cells with a dark green border are mandatory.
Cells with a light green or orange shade are scored, depending on the asset's primary sector. Not all scored cells are mandatory. Leaving a scored (i.e., shaded) cell blank will have negative scoring impacts. ‘Zero’ is an acceptable answer if it is true and accurate (i.e., if no target exists, the cell should be left blank).
Data
Instructions
Performance: Previous Year
It is not possible to edit any data in this column.
As previous-year data is directly drawn from the previous year's GRESB Asset Assessment, it is not possible to amend erroneous data. If the previous-year data is incorrect (for example, due to a reporting error), the entity can use the open text box below the indicator to inform investors. This column shows the reported performance for the previous year (e.g., calendar year 2024). If a metric is new or has changed substantially compared to last year’s assessment, or if there is no data available for the entity for the previous year, it is indicated as ‘N/A'.
Performance: Reporting Year
Enter data for performance during the reporting year for each metric.
For Renewable Power Sector Assets:
Scored and mandatory*: Reporting year performance of 'Total energy exported/sold'
For all other sectors:
Scored and mandatory*: Reporting year performance of 'Total energy consumed'
*GRESB automatically calculates some metrics based on the inputs of other mandatory cells. If these cells display “NA,” not all the required values for calculation have been provided yet.
The equations for the calculated cells are:
Total energy imported/purchased = Biofuels+ Renewable hydrogen + Waste (non-biomass) + Renewable electricity + Renewable steam, heating and cooling + Coal + Diesel + LPG, butane or propane + Motor gasoline + Natural gas + Non-renewable hydrogen + Other non-renewable fuel + Non-renewable electricity + Non-renewable steam, heating and cooling
% renewable energy imported/purchased = Biofuels + Renewable hydrogen + Waste (non-biomass) + Renewable electricity + Renewable steam, heating and cooling / Total energy imported/purchased * 100
Total energy generated onsite = Biofuels (produced onsite) + Geothermal + Hydro-electric + Solar + Wind + Nuclear + Other energy generation source
Total energy exported / sold = Biofuels + Renewable hydrogen + Renewable electricity + Renewable steam, heating and cooling + Coal + Diesel + LPG, butane or propane + Motor gasoline + Natural gas + Non-renewable hydrogen + Other non-renewable fuel + Non-renewable electricity + Non-renewable steam, heating and cooling
% renewable energy exported/sold = Biofuels + Renewable hydrogen + Renewable electricity + Renewable steam, heating and cooling / Total energy exported/sold * 100
Renewable energy consumed = Renewable energy imported/purchased + Renewable energy generated onsite - Renewable energy exported/sold
Renewable energy imported/purchased: From table Energy imported/purchased: Biofuels + Renewable hydrogen + Waste (non-biomass) + Renewable electricity + Renewable steam, heating, and cooling +
Renewable energy generated onsite: From table Energy generated onsite: Biofuels (produced onsite) + Geothermal + Hydro-electric + Solar + Wind -
Renewable energy exported/sold: From table Energy exported / sold: Biofuels + Renewable hydrogen + Renewable electricity + Renewable steam, heating and cooling
Non-renewable energy consumed = Non-renewable energy imported/purchased + Non-renewable energy generated onsite - Non-renewable energy exported / sold
Non-renewable energy imported / purchased: From table Energy imported / purchased: Coal + Diesel + LPG, butane or propane + Motor gasoline + Natural gas + Non-renewable hydrogen + Other non-renewable fuel + Non-renewable electricity + Non-renewable steam, heating and cooling +
Non-renewable energy generated onsite: From table Energy generated onsite: Nuclear + Other energy generation source
Non-renewable energy exported / sold: From table Energy exported / sold: Coal + Diesel + LPG, butane or propane + Motor gasoline + Natural gas + Non-renewable hydrogen + Other non-renewable fuel + Non-renewable electricity + Non-renewable steam, heating and cooling
Total energy consumed = Renewable energy consumed + Non-renewable energy consumed
% renewable energy consumed = Renewable energy consumed / Total energy consumed * 100
See definitions for each metric in the Terminology section below.
Target: Reporting Year
Enter any targets that were applicable for the reporting year for each metric.
For Renewable Power Sector Assets:
Scored but not mandatory: Reporting year target of 'Total energy exported/sold'
For all other sectors:
Scored but not mandatory: Reporting year target of 'Total energy consumed'
A reporting year target can be interpolated from a future-year target. The target (or the future-year target from which it is derived) must be formally adopted. This means that the entity must have set and communicated the target at least internally, and has implemented, or is preparing, actions to achieve the target.
Target: Future Year
Enter the relevant year for which the targets are set at the top of the column and enter the future-year targets for each metric where available.
For Renewable Power Sector Assets:
Scored but not mandatory: Future year target of 'Total energy exported/sold'
For all other sectors:
Scored but not mandatory: Future year target of 'Total energy consumed'
The target must be set for any future year that is not the reporting year. The target (or the future-year target from which it is derived) must be formally adopted. This means that the entity must have set and communicated the target at least internally, and has implemented, or is preparing, actions to achieve the target.
Data Coverage (%): Reporting Year
Insert a data coverage level from 0% to 100% in single-digit increments for each metric where required.
For Renewable Power Sector Assets:
Scored and mandatory: Data coverage of 'Total energy exported/sold'
For all other sectors:
Scored and mandatory: Data coverage of 'Total energy imported/purchased, 'Total energy generated onsite,' and/or 'Total energy exported/sold,' depending on whether the entity answers 'Yes' to the first three indicator questions.
Data coverage for any individual performance metric should represent an estimated percentage considering all material data related to all facilities and activities within the entity’s reporting boundary (RC3 and RC4) for the full reporting year.
Facility exclusions for data coverage
Facilities within an asset that have the following characteristics can be excluded from the reported data coverage levels:
Facilities under development.
Facilities that the asset has owned for less than 6 months.
Facilities that have been operational for less than 6 months.
Therefore, an asset can still report up to 100% data coverage for facilities even if it does not report data from facilities in the three categories noted above.
Note that if an asset reports less than 100% data coverage, its Benchmark Report will not display reporting-year performance data intensity values.
Data coverage calculation methodology
Describe the method used to calculate data coverage in the open text box below the performance tables.
Not scored but mandatory: Data coverage methodology
Include how the data was measured and how the coverage level was estimated or assessed (e.g., % coverage of facilities, output, GAV, or any other metric used).
Note on biofuels (produced onsite)
This metric in the table, “Energy generated onsite,” covers the onsite generation of biofuels, such as biogas. Entities that wish to report biogas generated as part of anaerobic digestion can use this metric.
Note on renewable electricity
Electricity should only be reported as renewable in the table “Energy imported/purchased” when it has been specifically acquired as such, for example, via a power purchase agreement (PPA) or other instrument. Purchased grid electricity should be reported under “non-renewable electricity,” even if the grid has partially decarbonized.
Note on energy transmission losses
Energy transmission losses are taken into account for the calculation of total energy consumption (Energy imported - Energy exported)
Intensities
It is not possible to edit any data in this section. GRESB automatically calculates intensity metrics based on data reported to other indicators.
If these cells display "N/A," it means that not all the required values for calculation have been provided yet. The equations for the calculated cells are:
Energy consumption intensity (/GAV) = “Total energy consumed” / “GAV”. GAV is reported in RC2 (Economic Size) and is converted from millions to units within the calculation.
Energy consumption intensity (/Revenue) = “Total energy consumed” / “Revenue”. Revenue is reported in RC2 (Economic Size) and is converted from millions to units within the calculation.
Energy consumption intensity (/Output) = “Total energy consumed” / “Output”. Output is reported in RC3 (Sector & geography) and is specific to the entity’s primary sector.
Energy export intensity (/GAV) = “Total energy exported / sold” / “GAV”. GAV is reported in RC2 (Economic Size) and is converted from millions to units within the calculation.
Energy export intensity (/Revenue) = “Total energy exported / sold” / “Revenue”. Revenue is reported in RC2 (Economic Size) and is converted from millions to units within the calculation.
Energy export intensity (/Output) = “Total energy exported / sold” / “Output”. Output is reported in RC3 (Sector & geography) and is specific to the entity’s primary sector.
Estimation Note
As a general rule, GRESB Participants are required to use actual data (i.e., directly measured from utilities or meters, documented, or derived using recognized standards) when reporting material performance data.
Broad extrapolations of data and general estimates should not be reported.
Participants must explain the methodology used to measure data and to calculate data coverage in an open text box below the performance table.
External Review
Select Yes or No: If selecting “Yes”, state whether the data submitted has been checked, verified or assured (select one option; the most detailed level of scrutiny to which the data was subjected). If selecting ‘verified’ or ‘assured,’ select the standard from the dropdown menu.
The Scheme Lists page contains the complete list of accepted assurance and verification schemes.
Additional assurance schemes may also receive recognition if they meet GRESB’s criteria. To submit a new scheme for review, please contact the GRESB team.
The final deadline for submitting a new assurance/verification scheme for review by the GRESB team is March 15th. Schemes submitted for review after March 15th will not be reviewed until the subsequent reporting year.
GRESB does not require the selected standard to be specific to energy data. As such, a standard initially designed to verify/assure non-energy data (e.g., water) can be selected as long as the same thoroughness and review criteria are applied to data reported in EN1.
Terminology
Biofuels
Any kind of energy carrier sourced from biological origin, including biodiesel, bioethanol, biogas, landfill gas, wood waste and other biomass products.
Data Coverage
The part of the asset for which data is available. Data coverage represents an estimated percentage considering all material data related to all facilities and activities within the entity’s reporting boundary for the full reporting year.
Electricity
In the context of this Assessment, electricity is a form of energy. Electricity purchased under a special agreement with a supplier (PPA, or Purchase Power Agreement) or directly sourced from or by a renewable generator can be reported under “Renewable electricity”. Purchased grid electricity should be reported in its entirety under “Non-renewable electricity” in the table “Energy imported/purchased”.
Energy consumed
Energy consumed on site in undertaking the entity's business activities and including losses. This is calculated as renewable energy consumed + non-renewable energy consumed.
Energy exported/sold
Any energy that the entity has supplied or distributed to third-parties, either the distribution of energy that has been imported by the entity, or energy that has been generated by the entity.
Energy generated onsite
Any energy generated or produced onsite. For example, solar PV-generated electricity.
Energy imported/purchased
Any energy that the entity has obtained or purchased from outside the entity's reporting boundaries.
Externally checked
Applies to instances when a third party has reviewed the data in a structured and consistent process, but no official certification has been awarded.
Externally verified
Applies to instances where a third party has reviewed the reporting against an existing scheme. When this checkbox is ticked, participants must select the scheme name from the dropdown.
Note that GRESB treats verification and assurance equally in the context of the assessment
Externally assured
Applies to instances where a third party has reviewed the data against an existing scheme. When this checkbox is ticked, participants should select the scheme name from the dropdown.
Note that GRESB treats verification and assurance equally in the context of the assessment
Geothermal
Energy generated from heat within the Earth's crust.
Hydro-electric
Energy generated from turbines powered by water, such as tidal energy, dams and water mills.
Hydrogen
A fuel that has no carbon emissions when combusted. Can be generated from hydrocarbons or electrolysis of water.

Scoring
Scoring: How does GRESB score this indicator?
Materiality-Based Scoring
The relevance of the 'Energy' issue (determined by the GRESB Materiality Assessment) defines this indicator's maximum score.
For more details, refer to the Asset Scoring Basics page or download the Asset Materiality & Scoring Tool.
Scoring of Metrics
Please refer to the table below for a summary of scoring based on the entity's primary sector.
Sector
Scoring Summary
Power Generation x-Renewables or Renewable Power Assets
Performance Data Disclosure: 50% of EN1 Only the Total metric in the Energy exported/sold table is scored. For this metric, the following fields must be completed to earn points as follows:
30% of the indicator score: based on the reporting of a value for Reporting-year performance
10% of the indicator score will be based on the reporting of a value in Reporting-year target
10% of the indicator score will be based on the reporting of a value in Future-year target
Data Coverage: 50% of EN1
The value for reporting-year data coverage will act as a multiplier to the points available for this metric. 50% of the total indicator score will be based on the value reported for gTotal energy exported/sold: Reporting-year performance Data Coverage
All Other Sectors
Performance Data Disclosure: 50% of EN1 Only the Total metric in the Energy consumed table is scored. For this metric, the following fields must be completed to earn points as follows:
30% of the indicator score: be based on the reporting of a value in Reporting-year performance
10% of the indicator score will be based on the reporting of a value in the Reporting-year target
10% of the indicator score: based on the reporting of a value in the Future-year target
Data Coverage: 50% of EN1
The value for reporting-year data coverage will act as a multiplier to the points available for this metric. Data coverage scoring distribution depends on how the entity reports its data. It will be split equally between the “Totals” in all completed performance tables (energy exported/sold, energy imported/purchased, energy generated onsite):
If an entity answers “yes” to only one of the three questions (has the entity imported or purchased energy, has the entity generated energy on site, and has the entity exported or sold energy), it must complete one performance table. Data coverage will be scored as 50% of the total indicator score, based on the data coverage value reported for the Total in the completed performance table.
If an entity answers “yes” to two of the three questions, it must complete two performance tables. 25% of the total indicator score will be allocated to the data coverage value for the Total metric reported in each performance table.
If an entity answers “yes” to all three questions, 16.7% of the total indicator score will be allocated to the data coverage value for the Total metric reported in each performance table.
If an entity answers 'no' to all three questions, data coverage levels will not be requested or scored, as the entity is not a consumer, generator, or exporter of energy.
Notes
To score for this indicator, participants reporting for all sectors must complete all cells with a green border.
Participants must input a target year under "Future-year target" and a numeric value for the underlying scored metric to score for this metric.
Not all scored cells/metrics are mandatory. If a scored (shaded) cell is not outlined in dark green, leaving it blank will still result in a negative scoring impact. This applies to the following metrics:
For participants whose primary sector is ‘Power Generation x-Renewables’ or ‘Renewable Power’ – Total energy exported/sold: Reporting-year target; Future-year target
For all other sectors – Total energy consumed: Reporting-year target; Future-year target.
Reporting of external data review is not scored.
If the entity reports data in the energy exported/sold table, the red ‘Data coverage’ metric in this table will also be scored.
Frequently Asked Questions
How should I calculate data coverage for performance data?
GRESB does not mandate a specific data coverage calculation methodology. Participants should report data coverage as an estimated percentage of the entity’s material facilities and activities within its reporting boundary (i.e. RC3 – Sector & Geography, and RC4 – Ancillary Activities) for which data was collected for the entire reporting year.
