Trusted by forward-thinking UK businesses
Every calculation is traceable from source data to output, built to GHG Protocol standards, and aligned with DEFRA 2024 conversion factors — so whatever question gets asked about your numbers, there is always a complete answer.
GreenScope automates the parts of carbon accounting that shouldn't require human time: emission factor matching, calculation, and report generation — so your team can focus on what only they can do.
Using official DEFRA/BEIS 2024 emission conversion factors, updated annually for UK businesses.
Emissions from sources owned or controlled directly by your company. Includes stationary combustion (gas, oil, LPG) and your owned vehicle fleet.
Indirect emissions from the generation of electricity, heat or steam your company purchases. Includes renewable tariff tracking for accurate market-based reporting.
All other indirect emissions across your entire value chain — the category that typically accounts for 70–90% of a company's total footprint.
Create your account with basic company details — industry, size, and reporting period.
Input energy bills, fuel usage, travel data, and waste figures across all three scopes.
GreenScope applies official DEFRA 2024 factors to calculate your tCO2e automatically.
