Carbon reporting
GHG Protocol Carbon Footprint
Scope 1, 2 and 3 organisational carbon footprints to the GHG Protocol — dual market- and location-based Scope 2, latest DEFRA factors, and a baseline ready for target-setting and disclosure.
What it is
Organisational carbon footprints across Scope 1, 2 and 3 prepared to the Greenhouse Gas Protocol Corporate Standard — the global benchmark for corporate carbon accounting.
All calculations use the latest DEFRA UK Government GHG conversion factors, with dual location-based and market-based Scope 2 reporting so the same footprint supports SECR, SBTi and investor disclosure.
We treat the footprint as a baseline, not a one-off compliance number — the methodology, boundary and data trail are documented so the numbers can be repeated, audited and built on year after year.
When you need it
- An investor, lender or customer is requiring a verifiable carbon disclosure.
- You are baselining emissions before setting a net zero or science-based target.
- You need supporting carbon figures for SECR or for an SBTi submission.
- You need to start reporting Scope 3 / supply chain emissions, not just energy and fuels.
- You want to replace an inherited spreadsheet footprint with a documented, defensible methodology.
Our approach
- 1
Emissions boundary setting
Define the organisational boundary (operational vs financial control) and the reporting boundary across Scope 1, 2 and the relevant Scope 3 categories.
- 2
Data collection
Collect activity data across stationary and mobile fuels, electricity, heat, business travel, employee commuting, purchased goods, transmission losses and other in-scope value chain categories.
- 3
Calculation using current DEFRA factors
Apply the latest DEFRA UK Government GHG conversion factors with the correct gas-by-gas treatment (CO2, CH4, N2O) and CO2e totals.
- 4
Dual Scope 2 reporting
Report Scope 2 on both a location-based and a market-based basis, with supplier-specific factors and supporting evidence (REGOs, contracts) where claimed.
- 5
Scope 3 treatment
Quantify the relevant Scope 3 categories and treat transmission & distribution losses as Scope 3 Category 3, in line with current GHG Protocol guidance.
- 6
Documented baseline
Lock down the inventory, methodology and assumptions as a year-on-year baseline ready for target-setting and external disclosure.
What you receive
Complete Scope 1, 2 and 3 footprint
A full organisational footprint covering Scope 1, Scope 2 and the relevant Scope 3 categories, in tCO2e.
Dual Scope 2 figures
Both location-based and market-based Scope 2 totals, with the supplier evidence supporting market-based claims.
Documented methodology
A clear methodology note covering boundary, data sources, factors, assumptions and any exclusions — audit-ready for verifiers or investors.
Baseline for target-setting
A documented baseline year and inventory structure ready to support net zero, SBTi or investor target-setting in subsequent years.
