What's New
Stay up-to-date on developments to GRESB's reporting experience, resources, and Standards.
Published March 31, 2026
Infrastructure Standard Development
The 2026 Infrastructure Standards updates reduce reporting burden through a more static Fund Assessment, sharpen focus on material issues such as sustainability-related risk and net zero, and ensure that GRESB results remain actionable and relevant.
Fund Assessment
The Fund Assessment becomes more static, reducing annual reporting where no material changes occur. Funds are encouraged to use the pre-fill functionality which is pre-selected upon starting the submission.
A few indicators remain not entirely pre-fillable due to their variable nature and are flagged to the user directly in the Assessment Portal. Some key highlights include:
RC2: Review of GAV and NAV values, which change annually.
RP1: This indicator has been simplified to require a single disclosure type, reducing reporting effort.
RC6 (Portfolio of Assets): Funds are encouraged to review and update any linked assets.
Asset Assessment
Updates include streamlining the reporting process and decreasing reporting burden for Participants, raising the bar on sustainability reporting and risk assessment requirements, and reflecting materiality outcomes for net zero more accurately.
Key highlights:
RP1: Simplified to require a single disclosure type, reducing reporting burden
GH2: Improved treatment of net-zero materiality for renewables assets and separate reporting on GHG emissions and net zero
RM2.1, RM2.2, RM2.3: Participants are now required to have identified, analyzed, evaluated, and treated the risks they select as part of the risk assessment indicators
NZIF Alignment Module integrated into the Asset Assessment
Minor updates to climate scenarios and management systems
Development Asset Assessment
Updates include measures to further streamline the reporting process and raise the bar for sustainability reporting.
Key highlights:
RP1: Simplified to require a single disclosure type, reducing reporting burden
Minor updates to climate scenarios and management systems
NZIF Alignment for Infrastructure
The GRESB NZIF Alignment Tool is now available as part of the GRESB Infrastructure Asset Assessment.
Following a successful pilot in 2025, the new tool, developed with IIGCC, provides a standardized approach to understanding how infrastructure assets, funds, and portfolios align with the Net Zero Investment Framework (NZIF). It uses existing GRESB data reported through the Asset Assessment alongside a short, voluntary GRESB NZIF Module.
The tool can help infrastructure investors, managers, and assets:
gain a consistent, comparable view of NZIF alignment across participating assets and portfolios
support clearer and more focused engagement on net-zero progress
reduce the need for multiple or bespoke NZIF-related data requests to managers and assets
Participation in the GRESB NZIF Module is optional and free for assets taking part in the GRESB Infrastructure Asset Assessment. As a result, assets that complete the module will receive a GRESB NZIF Alignment Report. Investors and managers with access to the asset’s GRESB Benchmark Report also receive access to the NZIF Alignment Report. Participation in the module does not affect GRESB Scores or benchmarks.
You can learn more about the GRESB NZIF Alignment Tool on the GRESB website.
For further details, the GRESB NZIF Module guidance is available here.
Improved GRESB Experience
GRESB has introduced several enhancements to reduce workload, improve usability, and strengthen data quality:
Assessment portal improvements:
Enhanced pre-fill function for Fund Assessment
Indicators with a scoring change due to Standard Updates will now be flagged with a 2026 Scoring Update label and linked to corresponding guidance
GRESB Assessment Q&A Webinar
On April 2nd, the GRESB Member Success team held a live webinar for participants to discuss and ask questions about the 2026 Infrastructure Assessments.

Resources & Support
GRESB Guides
Earlier this year, GRESB launched GRESB Guides, a redesigned resource platform that brings together all core assessment guidance and replaces legacy resource areas—making it easier to find the information you need.
Updated structure: In response to Member feedback, each assessment now has its own dedicated space consolidating key guidance into an all-in-one platform.
AI-supported search feature (Beta): GRESB Guides now includes an enhanced search feature that provides short, AI-supported answers directly from the search box. This feature is currently in Beta (testing phase) while GRESB continues to refine it and collect user feedback. Always verify responses against the official guidance and review this disclaimer before use.
GRESB Helpdesk
The GRESB Helpdesk is powered by the GRESB Member Success Team, dedicated to providing GRESB Members (Investors, Participants, and Partners) with timely and responsive support on the GRESB Assessment.
GRESB Participants requiring additional assistance with their submission can also refer to our network of contracted GRESB Partners. See our Partner Directory.
Strengthen Your Submission with GRESB
Starting April 1, participants can request a Pre-Submission Check—an evidence validation review which includes a one-hour call and a report outlining findings and feedback.
New in 2026:
Technical Expert Touchpoint: Available year-round, this service provides focused, one-on-one face time engagement with a GRESB Member Success expert, offering tailored guidance at any stage of your GRESB journey.
Success Suite: A new bundled offering that brings together core premium support elements in the GRESB journey, including: one GRESB AP seat, one Technical Expert Touchpoint, one Pre-Submission Check, eligibility to opt in to Assessment Correction, and one Results Performance Review (formerly Results Consultation).
Post-assessment services: Get familiar with the Assessment Correction and Results Performance Review for a thorough review of your assessment results. In 2024, participants who used the Results Performance Review saw their GRESB score jump by approximately seven points on average compared to the year before.
For any questions about the Assessments, services, or products, please contact the GRESB Member Relations team.
Technical Clarifications
This section will note any clarifications or additions that GRESB makes to the assessment guidance from April 1st onwards.
Independent third-party definition (RP1, GH1): Positioned the definition as a set of exemplary characteristics underpinning 'independence,' rather than a set of hard restrictions, by removing the reference to "must."
