Why NuboGreen

ESG reporting is becoming mandatory. Most startups aren't ready.

UK SECR reporting, enterprise vendor questionnaires, investor ESG due diligence — they all need cloud carbon data. NuboGreen gives you the numbers, the report, and the roadmap.

📋

UK SECR Compliance

Streamlined Energy and Carbon Reporting is mandatory for large UK companies — and increasingly expected by enterprise clients during supplier vetting. NuboGreen produces SECR-ready data.

🏆

Enterprise Vendor Questionnaires

Enterprise clients increasingly require suppliers to disclose carbon data. NuboGreen gives you the exact numbers and language needed to answer ESG sections of RFPs and vendor questionnaires.

💚

Investor ESG Due Diligence

ESG metrics are increasingly part of investor due diligence, particularly for Series A and beyond. NuboGreen gives you a defensible, methodology-backed carbon number.

What we measure

Every watt. Every service. Every region.

NuboGreen uses actual AWS CloudWatch metrics — not estimates — to calculate real energy consumption per service.
