Building level emissions data for TCFD compliance
Stop guessing your financed emissions. Granyt’s machine learning platform is built on our live UK commercial property database (13M records). Delivers building-level emissions with PCAF Data Quality Score 3 for 95%+ of any portfolio.
The emissions reporting challenge
TCFD and ISSB standards require building-level emissions data for financed emissions reporting. Until recently, using generic country or sector estimates for building emissions was acceptable - that's how most of the 630 financial institutions signed up to PCAF have reported. But new standards in December 2025 raised the bar. Regulators and investors now expect building-specific data, not estimates.
Most organisations hire consultants to gather EPC certificates, chase missing data, and commission new EPCs where records are out of date. It costs £500-5,000 per property and can take months for a large portfolio. That's before you've calculated a single emission. For complex multi-tenanted commercial sites, EPCs are often out of date, logged across different years with different emissions conversion factors.
Energy certificates exist for most commercial buildings - but many contain errors. Wrong fuel types, incorrect floor areas, outdated information. Multi-tenanted buildings add another layer: separate energy supplies, shared heating systems, certificates that cover only part of the building. Piecing together accurate whole-building emissions is harder than it looks.
Building-level emissions data without the consultants
The UK has more public building data than most people realise - over 13 million energy certificates, valuation records, and property characteristics. The problem isn't missing information. It's that no one has stitched it together.
Granyt does.
Our platform links fragmented records to create a complete picture of each building. Where certificates are missing or outdated, machine learning predicts fuel types and energy use based on building characteristics. Automated checks flag outliers - implausible floor areas, mismatched fuel types, certificates based on defaults rather than surveys.
And because the grid is decarbonising fast, we adjust for in-year emissions factors - so your data reflects what the building is emitting now, not what it would have emitted five years ago.
The result: validated, building-specific emissions data for your whole portfolio. PCAF Score 3 quality. Delivered in weeks, not months. No site visits, no consultants, no chasing tenants.
How it works
Send us a list of your properties - addresses, postcodes, or UPRN references. A spreadsheet is fine. We match each one against our database of 13 million UK property records, linking EPC certificates, valuation data, and building characteristics. Multi-tenanted buildings are identified and pieced together automatically.
For each building, we extract energy data and calculate emissions using current conversion factors. Where certificates are missing, outdated, or incomplete, our machine learning model predicts fuel type and energy intensity based on building age, size, use, and location. Every record runs through automated checks - flagging implausible floor areas, fuel type mismatches, and certificates that look like they were generated from software defaults rather than actual surveys.
We deliver a complete emissions profile for your portfolio: kgCO₂e per building, methodology notes, data quality flags, and full audit documentation. Output comes as Excel plus a summary PDF - ready for your TCFD disclosure, your sustainability team, or your board.
