[SCORING KEY] A 'scoring weight' is the fraction of the indicator's maximum score that a selection contributes (a multiplier, not a fixed point value). INPUT TYPES: groups are labelled (radio - select exactly one; options are mutually exclusive) or (checkbox - select all that apply); radio options are alternatives, checkbox options add together. CAPPING: total scoring is capped at the indicator's maximum (1/1). VALIDATION: where an indicator is subject to validation, validation is applied at the INDICATOR level - the whole indicator receives one status that multiplies its total score: Accepted x1 (full points), Partially Accepted x0.5 (half points), Not Accepted x0 (no points). When asked how many points a set of selections would earn on a validated indicator, FIRST state the points the selections are eligible for, THEN give all three outcomes (Accepted = full eligible points, Partially Accepted = half, Not Accepted = zero) rather than assuming any one outcome. T1.1 | Portfolio Improvement Targets. Maximum score: 1 point. Subject to validation: No indicator-level or subsection-level evidence validation multiplier is shown for this indicator. Indicator score: sum of reported target scoring weights, capped at 1/1, × 1 point. Scoring basis: Participants receive 2/9 of the maximum score for each reported target and an additional 1/9 if that target is externally communicated. For each reported target: Reported target — 2/9 total scoring weight. Externally communicated target — additional 1/9 total scoring weight. Reported and externally communicated target — 2/9 + 1/9 = 3/9 total scoring weight. The sum across all reported targets is capped at 1/1 total scoring weight. Other-answer validation: The “Other” target row can separately be marked Accepted, Duplicate, or Not Accepted. This is NOT a validation multiplier. The Other-answer validation decision applies only to the scoring of that specific Other target itself. If the Other answer is Accepted, that Other target can earn its stated scoring weight. If Duplicate or Not Accepted, that Other target earns 0 scoring weight. This decision does not multiply the indicator score, subsection score, or any other target rows. Does the entity have portfolio improvement targets? (radio - select exactly one; options are mutually exclusive) Yes — 0 scoring weight by itself. Selecting Yes reveals the scored target table. No — 0 scoring weight. Portfolio improvement target table (table fields; each completed target row can contribute scoring weight) For each area, a reported target earns 2/9 total scoring weight. If that same target is externally communicated, it earns an additional 1/9 total scoring weight. Target rows Energy consumption — reported target = 2/9 total scoring weight; if externally communicated, add 1/9, for a maximum of 3/9 total scoring weight for this row. Renewable energy use — reported target = 2/9 total scoring weight; if externally communicated, add 1/9, for a maximum of 3/9 total scoring weight for this row. GHG emissions — reported target = 2/9 total scoring weight; if externally communicated, add 1/9, for a maximum of 3/9 total scoring weight for this row. Water consumption — reported target = 2/9 total scoring weight; if externally communicated, add 1/9, for a maximum of 3/9 total scoring weight for this row. Waste diverted from landfill — reported target = 2/9 total scoring weight; if externally communicated, add 1/9, for a maximum of 3/9 total scoring weight for this row. Building Certifications — reported target = 2/9 total scoring weight; if externally communicated, add 1/9, for a maximum of 3/9 total scoring weight for this row. Data Coverage — reported target = 2/9 total scoring weight; if externally communicated, add 1/9, for a maximum of 3/9 total scoring weight for this row. Other: [free text] — reported target = 2/9 total scoring weight; if externally communicated, add 1/9, for a maximum of 3/9 total scoring weight for this row, subject to the separate Other-answer validation decision described above. Fields for each target row Not scored separately, but used to define each reported target. Target type: [dropdown field]. Long-term target (%): [numeric percentage field]. Baseline year: [year field]. End year: [year field]. Are these targets communicated externally?: [dropdown field]. If the target is externally communicated, add 1/9 total scoring weight for that target row. Methodology field Not scored separately. Explain the methodology used to establish the targets and communicate the anticipated pathways to achieve these targets: [text field, maximum 250 words].

Intent: What is the purpose of this indicator?

Environmental performance targets help guide organizations toward measurable improvements and support the integration of sustainability into day-to-day operations. This indicator evaluates whether the entity has established credible targets, without assessing the ambition level of those targets.

Input: How do I complete this indicator?

Select yes or no. If yes, select all applicable sub-options. If yes, complete the table for all applicable performance indicators for the entire portfolio’s targets. **Baseline year:** Include a baseline year. Participants have the option to select a baseline year from 2000 onwards. **End year:** This is the end date for the long-term reduction targets. It must be 2026 or later and at least three years later than the baseline year. **Externally communicated:** Select yes or no for each performance indicator target. **Target type:** Select from the dropdown menu whether the performance indicator target is based on absolute or like-for-like data, or intensity-based. * **Examples:** * *Reduce electricity consumption by 15% across the same operational assets between 2021 and 2026. Only includes buildings that have not changed significantly in composition or boundary.* * **Area**: Energy Consumption * **Target type**: Like-for-like * **Long-term target** %: 15 * **Baseline year**: 2021 * **End year**: 2026 * *Reduce water consumption from 150 to 120 liters per person by 2027.* * **Area**: Water Consumption * **Target type:** Intensity-based * **Long-term target** %: 20 * **Baseline year:** 2020 * **End year**: 2027 * *Starting in 2015, increase coverage of building certifications to reach a 50% certified portfolio by 2027.* * **Area:** Building Certifications * **Target type:** Absolute * **Long-term target** %: 50 * **Baseline year**: 2015 * **End year:** 2027 #### Terminology **Absolute data** > An absolute consumption, emission or production measure provided by an entity regarding its emissions and/or use of Energy / GHG Emissions / Water / Waste etc. for the reporting year. **Externally communicated** > The targets that are shared with any third party and are not restricted solely to an internal audience within the reporting entity. Examples include public disclosures, communications to investors, etc. **Intensity data** > Calculated based on the amount of Energy / GHG Emissions /Water / Waste etc. used or produced per unit of an appropriate denominator, usually the floor area covered (e.g., for energy this would be kWh/m2). **Like-for-like data** > Calculated based on 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. **Long-term performance improvement targets** > A target that projects three or more years into the future, with the purpose of improving the portfolio’s performance through a reduction of any energy or water consumption, GHG emissions or waste to landfill, or an increase in sustainability data or building certifications coverage.

Validation: What evidence is required?

No evidence required. Only the 'Other' answer is manually validated. #### **Other Answer** State the other performance indicator for which you have set a long-term target. Other answers must be outside the options listed in the question, but must be related to performance indicators. Validation Basics

## Scoring

Scoring: How does GRESB score this indicator?

Participants receive 2/9 of the maximum score for each reported target and an additional 1/9 if the target is externally communicated. **Other:** The 'Other' answer is manually validated and assigned a score, which is used as a multiplying factor, as per the table below: | Validation status | Score | | ----------------- | ----- | | Accepted | 1/1 | | Not Accepted | 0 | | Duplicate | 0 | **Open text box:** The open text box is not scored and is for reporting purposes only.
