GHG inventory and carbon footprint consulting
A greenhouse gas inventory is the starting point for every climate commitment: customer questionnaires, SBTi targets, CDP responses, bank ESG checks and tender requirements all ask for the same Scope 1, 2 and 3 numbers.
We build the inventory to the GHG Protocol Corporate Standard, document every activity source and emission factor so an auditor can follow it, and hand over a workbook your team can update next year without us.
The problem we solve
A customer asks for your Scope 1, 2 and 3 footprint and nobody in the team has done one.
What is included

Frequently asked questions
What does a GHG inventory consultant do?
Sets your organisational boundary, collects activity data (fuel, electricity, travel, purchases), applies documented emission factors and calculates Scope 1, 2 and 3 emissions to the GHG Protocol, then sets a base year for tracking.
How much does a carbon footprint assessment cost?
Our GHG inventories start from $400 for a small organisation with good records. The price depends on the number of sites, data quality and how many Scope 3 categories are material; you get a fixed written quote after a free call.
Do you calculate Scope 3?
Yes. We screen all 15 Scope 3 categories, estimate them with spend-based factors first, and replace the largest with activity or supplier data where it matters.
How long does it take?
Usually 3 to 6 weeks, most of it waiting for data. A clear data request at the start keeps it short.
