Purpose of this article
This article explains the methodology behind Scaler's proprietary performance scores and how to interpret them. It covers the Scaler ESG Score, Scaler Net Zero Energy Score, and Scaler Net Zero Carbon Score, along with guidance on using these metrics to track progress and communicate performance.
Overview of scoring in Scaler
Scores in Scaler are designed to contextualize sustainability performance, not replace raw metrics.
All scores:
- Are calculated using available data in the platform
- Follow transparent, logic-driven methodologies
- Align with leading ESG reporting practices in real estate
- Are available at both asset and portfolio level
Different scores serve different purposes, from internal performance tracking to decarbonization pathway alignment to external reporting preparation.

Scaler ESG Score
The Scaler ESG Score provides a holistic performance score out of 100 points for each asset, aggregated at portfolio level.
What the score measures
The score is structured around seven key aspects aligned with industry reporting standards:
Energy (25%): Includes renewable energy, energy use intensity (EUI), data coverage, and like-for-like consumption trends. EUI performance is assessed against CRREM 1.5°C decarbonization pathways.
GHG Emissions (12%): Covers carbon intensity (including CRREM alignment), like-for-like change, and data coverage.
Water (12%): Focuses on data coverage, like-for-like change, and the proportion of water reused or recycled.
Waste (7%): Assesses data coverage and diversion rates (recycling, reuse, waste-to-energy).
Building Certifications (19%): Based on the share of gross floor area (GFA) covered by energy ratings and environmental certifications.
Tenant Engagement (9%): Includes engagement programs, satisfaction surveys, green leases, and fit-out practices.
Risk & Technical Assessments (16%): Reflects presence of risk assessments, technical audits, and operational efficiency measures across energy, water, and waste.
How the score is calculated
Each of the seven aspects contains multiple sub-indicators that contribute to the weighted percentage. For example, the Energy aspect (25% of total score) includes:
- Renewable energy procurement
- Energy use intensity performance vs CRREM pathways
- Energy data coverage across the asset
- Like-for-like energy consumption trends
Asset-level scores are calculated based on data completeness, performance metrics, and alignment with decarbonization targets. Missing data in any aspect will result in a lower score for that aspect.
At portfolio level, the ESG Score is calculated as a floor-area-weighted average of asset scores and is available across time for year-on-year tracking.
How to interpret the score
Expand
Score of 75-100: Strong ESG performance with comprehensive data coverage and good alignment with sustainability targets. Assets in this range typically have high data quality, certifications, and improving like-for-like performance.
Score of 50-74: Moderate ESG performance with room for improvement. May indicate data gaps in some aspects or weaker performance on intensity metrics or certifications.
Score of 25-49: Significant improvement opportunities. Likely indicates missing data in multiple aspects, lack of certifications, or poor alignment with decarbonization pathways.
Score below 25: Critical gaps in data coverage or performance. Priority should be on completing data collection and understanding where the asset stands on key metrics.
Tip
The ESG Score is most useful for tracking relative performance across your portfolio and identifying which assets need the most attention. Use the aspect-level breakdown to understand which specific areas (energy, water, certifications, etc.) are driving the score up or down.
Where to view the score
Navigate to Analytics Portal → Portfolio → Overview to view:
- Portfolio-level Scaler ESG Score
- Scaler ESG Aspect scores showing performance breakdown across the seven aspects

Note: These scores are only visible if the Show Scaler Scores toggle is enabled in Data Collection Portal → Portfolio → Settings.

Scaler Net Zero Energy Score
The Scaler Net Zero Energy Score evaluates how well an asset's energy performance aligns with long-term energy-reduction targets. It compares an asset's energy use intensity (EUI) to the CRREM 1.5°C energy pathway for the relevant property subtype and region.
How the score is calculated
The score is derived by comparing the asset's EUI to the CRREM pathway threshold for the reporting year:
SCORE = 100 - [(EUI_ASSET - EUI_2050) / (EUI_YEAR - EUI_2050) × 100]
Where:
- EUI_ASSET = Asset's energy use intensity for the most recent year with data
- EUI_YEAR = CRREM pathway target EUI for that same year
- EUI_2050 = CRREM 2050 target EUI
Score capping:
- If EUI_ASSET > EUI_YEAR, the score is capped at 0 (misaligned with pathway)
- If EUI_ASSET ≤ EUI_2050, the score is capped at 100 (already meets 2050 target)
How to interpret the score
Expand
Score of 100: The asset's EUI in the reporting year is already below the 2050 CRREM energy threshold for its region and property subtype. The asset meets long-term energy efficiency targets today.
Score of 75-99: The asset is performing better than the current year's CRREM pathway target and is on track to meet 2050 targets with moderate continued improvement.
Score of 50-74: The asset is moderately aligned with the pathway but will need significant energy efficiency interventions to meet 2050 targets.
Score of 25-49: The asset is below the current year's CRREM pathway target. Substantial energy reduction measures are needed to align with decarbonization goals.
Score of 0: The asset's EUI significantly exceeds the CRREM pathway threshold. This indicates urgent need for energy efficiency improvements.
No score shown: The asset does not have sufficient data to calculate EUI for the reporting year. This typically means missing energy consumption data or gross floor area data.
Warning
The Net Zero Energy Score depends on accurate property type mapping and complete energy consumption data. If your property type is incorrectly mapped in Scaler, the CRREM pathway comparison will not be meaningful.

Scaler Net Zero Carbon Score
The Scaler Net Zero Carbon Score assesses alignment with a science-based net zero carbon trajectory. It compares Scope 1 and 2 GHG emissions intensity to the CRREM 1.5°C carbon pathway.
How the score is calculated
The score is based on how the asset's GHG emissions intensity compares to the CRREM carbon threshold for the reporting year:
SCORE = 100 - [(GHG_ASSET - GHG_2050) / (GHG_YEAR - GHG_2050) × 100]
Where:
- GHG_ASSET = Asset's GHG emissions intensity for the most recent year with data
- GHG_YEAR = CRREM pathway target GHG intensity for that same year
- GHG_2050 = CRREM 2050 target GHG intensity
Score capping:
- If GHG_ASSET > GHG_YEAR, the score is capped at 0 (misaligned with pathway)
- If GHG_ASSET ≤ GHG_2050, the score is capped at 100 (already meets 2050 target)
How to interpret the score
Score of 100: The asset's GHG emissions intensity in the reporting year is already below the 2050 CRREM carbon threshold for its region and property subtype. The asset meets long-term decarbonization targets today.
Score of 75-99: The asset is performing better than the current year's CRREM pathway target and is on track to meet 2050 targets with continued carbon reduction efforts.
Score of 50-74: The asset is moderately aligned with the pathway but will need significant decarbonization interventions—energy efficiency, renewable energy procurement, or fuel switching—to meet 2050 targets.
Score of 25-49: The asset is below the current year's CRREM pathway target. Substantial carbon reduction measures are needed to align with net zero goals.
Score of 0: The asset's GHG intensity significantly exceeds the CRREM pathway threshold. This indicates urgent need for decarbonization interventions.
No score shown: There is not enough emissions data to calculate GHG intensity for that year. This typically means missing energy consumption data, incorrect emission factors, or missing gross floor area data.
Understanding the relationship between Energy and Carbon scores
The Net Zero Energy Score and Net Zero Carbon Score often move together because GHG emissions are largely driven by energy consumption. However, they can diverge:
- An asset with high renewable energy procurement may have a high Carbon Score (low emissions) but a moderate Energy Score (still consuming energy, just from clean sources)
- An asset in a region with a clean electricity grid may score better on Carbon than Energy
- Assets that switch from high-carbon fuels (oil, coal) to lower-carbon alternatives (natural gas, electricity) may see Carbon Score improvements even if total energy consumption stays the same
Monitor both scores to understand whether performance improvements are coming from energy efficiency (reducing total consumption) or carbon reduction strategies (cleaner energy sources).

GRESB scoring and dashboard
In addition to Scaler's proprietary performance scores, Scaler provides tools to model and estimate GRESB scores using the same scoring methodology applied by GRESB, based on asset-level performance indicators.
The GRESB Dashboard helps you:
- Estimate GRESB performance before submission
- Track expected progress throughout the year
- Identify improvement opportunities across GRESB indicators
- Understand which assets contribute most to portfolio-level scores
Important: GRESB score modeling in Scaler is indicative, not predictive. It does not include GRESB's benchmarking or validation adjustments.
To access the GRESB Dashboard, navigate to Analytics Portal → Scores.
For detailed information on using the GRESB Dashboard, see the dedicated article on GRESB Dashboard and Score Modeling.

Use cases for scores
Scaler's scoring tools are designed to support multiple stakeholder needs and use cases:
Internal performance tracking
Use scores to monitor portfolio performance over time and identify assets that need attention. The ESG Score provides a holistic view, while the Net Zero Energy and Carbon Scores focus specifically on decarbonization pathway alignment.
Example workflow: Run quarterly reviews of portfolio ESG Scores to identify assets that have declined quarter-over-quarter, investigate root causes (data gaps vs actual performance decline), and prioritize corrective actions.
Asset prioritization and capital planning
Use scores to prioritize which assets receive capital investment for energy efficiency improvements, renewable energy installations, or certification pursuits.
Example workflow: Sort assets by Net Zero Energy Score to identify buildings furthest from CRREM pathway alignment. Model the impact of proposed capital improvements on pathway alignment to justify investment decisions.
Stakeholder communication
Use scores to communicate performance to investors, lenders, tenants, and other stakeholders who need high-level performance summaries without diving into raw consumption metrics.
Example workflow: Include ESG Score trends in quarterly investor reports to demonstrate portfolio-wide sustainability performance and year-over-year improvement trajectory.
GRESB and ESG reporting preparation
Use the GRESB Dashboard to prepare for GRESB Real Estate Assessment submission by identifying data gaps and estimating scoring potential before the reporting deadline.
Example workflow: Six months before GRESB submission, review the GRESB Dashboard to identify which assets are missing data for key indicators. Prioritize data collection efforts on high-impact gaps that affect scoring.
Decarbonization planning and target setting
Use Net Zero Energy and Carbon Scores to understand how your portfolio aligns with science-based decarbonization pathways and where interventions are most urgently needed.
Example workflow: Set internal targets for minimum Net Zero Carbon Scores by 2030 and 2040. Track annual progress against those targets and model the impact of planned interventions (renewable energy procurement, building retrofits) on future scores.
Best practices for using scores
Expand
Complete data collection first
Scores are only as good as the data behind them. Before using scores for decision-making, ensure you have:
- Complete energy consumption data for all major energy sources
- Accurate gross floor area (GFA) data
- Current certification and energy rating records
- Properly configured emission factors
Assets with significant data gaps will show artificially low scores that don't reflect actual performance.
Track trends, not absolute values
A single score at a point in time provides limited insight. Track scores year-over-year to understand whether your sustainability initiatives are working and whether you're moving in the right direction.
Example: An ESG Score of 65 might seem mediocre, but if it was 50 last year and 40 the year before, that upward trend demonstrates meaningful progress.
Use aspect-level breakdowns
For the Scaler ESG Score, don't just look at the overall score—drill down into the seven aspects to understand what's driving performance. An asset might have a moderate overall score but very strong energy performance and weak certification coverage. That tells you where to focus improvement efforts.
Understand regional and property type context
Net Zero Energy and Carbon Scores compare assets to CRREM pathways specific to their region and property subtype. A score of 60 for an office building in Amsterdam means something different than a score of 60 for a retail property in Phoenix—different baseline energy intensities and climate conditions.
Don't compare scores across different property types or regions without understanding the underlying pathway differences.
Combine scores with raw metrics
Scores are designed to contextualize performance, not replace raw metrics. When investigating why an asset has a low score, look at the underlying consumption data, intensity metrics, and data coverage to understand the root cause.
Set realistic improvement targets
Use your current score distribution to set achievable improvement targets. If your portfolio average ESG Score is 55, setting a target of 90 within one year is unrealistic. Instead, target incremental improvements (e.g., move from 55 to 65) with specific initiatives tied to score components.
Filter and segment for insights
Use Scaler's filtering capabilities to analyze scores by property type, country, asset group, or other attributes. This helps you understand whether certain segments of your portfolio are underperforming and need targeted interventions.
Understanding score limitations
Scores reflect data availability
If an asset is missing data for certain aspects (e.g., no waste data, no certification records), the score will be lower even if the asset performs well on other aspects. Missing data can make an asset appear worse than it actually is.
Solution: Focus first on completing data collection before drawing conclusions about performance from scores.
CRREM pathway assumptions
The Net Zero Energy and Carbon Scores rely on CRREM pathway assumptions about property type, climate zone, and energy mix. If your asset's CRREM property type mapping is incorrect, the score comparison won't be meaningful.
Solution: Verify that property types are correctly mapped in Scaler. See the article on property type mapping for GRESB, CRREM, and ULI for detailed guidance.
Scores don't capture nuance
A score is a single number that simplifies complex performance across multiple dimensions. Two assets with the same ESG Score might have very different strengths and weaknesses across the seven aspects.
Solution: Always review the aspect-level breakdown and underlying metrics, not just the overall score.
Year-over-year comparisons require consistent data
If you significantly improve your data coverage from one year to the next, your scores may appear to decline even if actual performance improved—because you're now measuring more comprehensively.
Solution: When tracking year-over-year score changes, check whether data coverage changed significantly. Normalize for data availability when comparing across years.
Troubleshooting & common mistakes
I don't see Scaler ESG Scores anywhere in my Analytics Portal
Check whether the Show Scaler Scores toggle is enabled. Navigate to Data Collection Portal → Portfolio → Settings and verify the toggle is turned on. When disabled, Scaler scores are hidden throughout the platform.
My Net Zero Energy Score is 0 even though my asset has good energy performance
A score of 0 means your asset's EUI exceeds the current year's CRREM pathway threshold for your property type and region. This doesn't mean performance is bad in absolute terms—it means the asset isn't aligned with the science-based decarbonization pathway. Check the Roadmaps dashboard to see how far your EUI is from the pathway and what level of improvement is needed.
My ESG Score went down even though we improved energy efficiency
Check whether you added new data categories this year. If you started tracking waste or water data that was previously missing, your score may appear to decline because you're now being measured on aspects that were previously zero. Also check like-for-like consumption trends—if other assets improved more than yours, your relative score may decrease.
I don't have a Net Zero Carbon Score for my asset
This typically means you're missing GHG emissions data or gross floor area data. Check that you have energy consumption data entered, that your emission factors are properly configured, and that the asset has a valid GFA value.
My GRESB score estimate doesn't match my final GRESB score
GRESB score modeling in Scaler is indicative only. GRESB applies benchmarking against peer groups, validation by assessors, and interpretation of responses that Scaler cannot replicate. Use the GRESB Dashboard for improvement planning, not score prediction.
Two assets with similar consumption have very different Net Zero Energy Scores
Check whether they have the same property type and region. CRREM pathways vary significantly by property subtype and climate zone. An office building and a retail property in the same city will be compared to different pathways, resulting in different scores even with similar consumption.
My certification data is entered but not showing in the ESG Score
Verify that certifications have valid issue dates and haven't expired. Scaler only counts active certifications when calculating the Building Certifications aspect. Also check that the certification is mapped to the correct asset in the platform.
