Excellence in real estate

The GRESB real estate assessment

GRESB (formerly the Global Real Estate Sustainability Benchmark) is the leading global ESG benchmark for real estate and infrastructure investors, managers, and operators. The GRESB Real Estate Assessment evaluates the sustainability performance of real estate portfolios and development activities, translating ESG practices and asset-level data into a standardized, validated benchmark used in investment decision-making.

Two components. One score.

The GRESB Real Estate Assessment evaluates performance across two core components — each demanding a different type of expertise and execution rigor.

Management component

Policy, governance, and management practices

Evidence-validated indicators covering leadership, policies, reporting, and stakeholder engagement. Greenplaces reporting leads own narrative responses and portal data entry — ensuring your management component reflects real maturity and is supported by credible evidence.

Performance component

Asset-level energy, emissions, water, and waste data

Relative benchmarking across quantitative asset-level performance indicators. Our carbon accountants own data collection, coverage logic, calculations, and quality assurance — transforming raw meter data into defensible, benchmark-ready performance scores.

GRESB performance matters

GRESB is widely used by institutional investors, limited partners, lenders, and rating agencies to assess ESG risk, management maturity, and year-over-year improvement. For growing portfolios, execution risk is highest during asset data compilation, coverage logic, and quality assurance — exactly where Greenplaces takes ownership.

  • ESG risk exposure across real estate portfolios

  • Management maturity and governance practices

  • Asset-level performance trends and data coverage

  • Year-over-year improvement and credibility of reporting

  • Capital allocation and lender credit decisions

Scoring and timelines

GRESB scoring and key dates

GRESB scores range from 0 to 100 and are benchmarked relative to peer groups. Results are translated into a 1- to 5-star GRESB rating. For first-time submitters or rapidly growing portfolios, execution risk is highest during asset data compilation and quality assurance.

What Greenplaces delivers

Common GRESB challenges we solve

GRESB has become increasingly data- and asset-intensive, with performance scores driving outcomes. From bridging the gap between existing practices and new standards, to building a submission-ready foundation that scales, we’ve got you covered.

Without specialized support, these challenges can materially impact scores and investor perception.

Asset-level data at scale

Managing asset-level spreadsheets and coverage logic at scale is the single biggest execution risk in GRESB. Greenplaces carbon accountants own this work — building structured data templates, chasing utility providers, and applying coverage logic that maximizes your performance score.

Asset data | Coverage logic | Utility management

Data quality and comparability

Meeting rising expectations for data quality, comparability, and evidence requires deep familiarity with GRESB’s technical methodology. We quality-assure every data point before submission, catching errors that would otherwise cost you points.

Quality assurance | Evidence review

Scoring mechanics and performance math

Interpreting GRESB’s performance math and scoring mechanics requires specialist knowledge. Greenplaces translates the benchmark framework into a clear picture of where your points are coming from — and where improvement is achievable.

Score analysis | Benchmark interpretation

Internal resourcing and team capacity

Resourcing internal teams to support collection, QA, and submission is a persistent challenge — especially for lean sustainability teams managing multiple reporting obligations simultaneously. Greenplaces acts as an extension of your team, owning the workload.

Reporting execution | Team extension

First-time submissions and growing portfolios

Reducing risk for first-time submissions or rapidly growing portfolios requires a structured approach from day one. We build a repeatable data infrastructure designed to improve your score year over year — not just get through this cycle.

White-glove GRESB delivery

A different approach to GRESB support

Greenplaces delivers true white-glove GRESB support designed for execution, not theory. As a certified Real Estate Assessment partner, we don’t just offer advisory — we take ownership of the work, so your team can focus on what matters most.

Our delivery model pairs carbon accountants with reporting leads to cover every dimension of the assessment — from raw utility data through narrative management responses and final portal submission.

Carbon accountants own performance

Asset-level data, calculations, coverage logic, and QA over the performance component — delivered by specialists who understand GHG accounting and GRESB’s technical methodology.

Reporting leads own management

Management component narrative responses and portal data entry managed by reporting leads who know what evidence GRESB expects and how to present it effectively.

Support beyond submission

Hands-on support during both the GRESB submission cycle and the off-cycle improvement planning period — building a foundation for stronger results year over year.

PART OF A BROADER ESG REPORTING STRATEGY

Beyond GRESB: broader investor ESG support

For many organizations, GRESB is part of a broader ESG and climate reporting ecosystem. Greenplaces supports adjacent investor-driven requirements — so your data infrastructure works across every framework you face.

→
Carbon accounting and assured GHG inventories
The GRESB performance component relies on accurate, well-structured GHG data. Greenplaces carbon accounting software provides the underlying calculations — with assurance-ready documentation that holds up to investor scrutiny.

→
Physical and transition climate risk assessments
GRESB increasingly integrates climate risk into scoring. Greenplaces delivers physical and transition risk assessments aligned with TCFD, ISSB, and SFDR requirements — supporting both GRESB responses and broader investor disclosure obligations.

→
Net-zero target setting and decarbonization planning
Science-based targets and net-zero pathways strengthen your GRESB management component and demonstrate long-term credibility to investors. Greenplaces integrates target-setting with your annual GRESB reporting cycle.

→
CDP, SFDR, ISSB, and lender ESG requests
GRESB data has significant overlap with CDP, SFDR, and ISSB disclosures. Greenplaces coordinates across frameworks to maximize data reuse, reduce duplication, and meet the full range of investor and lender ESG requests your portfolio faces.
