What a carbon consultancy does
A carbon consultancyis a specialist firm focused on measuring and managing an organisation's greenhouse-gas emissions.
The foundation is a Scope 1, 2 and 3 carbon footprint built on the GHG Protocol Corporate Standard3 using the UK Government's DESNZ conversion factors1.
From there a carbon consultancy supports compliance, reduction and — for residual emissions — offset strategy.
Carbon footprint consultancy
A carbon footprint consultancy specialises in the measurement step: collecting activity data, applying emission factors, and producing an auditable inventory.
Scope 3 — value-chain emissions across fifteen categories — is usually the hardest part, and our Scope 3 under UK SRS guide sets out how it is estimated3.
A robust footprint is the prerequisite for SECR, UK SRS S2 disclosure, and any net zero target.
Carbon compliance consultancy
A carbon compliance consultancy focuses on meeting UK regulatory obligations rather than measurement for its own sake.
That means SECR disclosure in the Directors' Report2, ESOS energy audits, and the climate disclosures of UK SRS S24.
The value is ensuring figures are calculated correctly and presented in the exact format each regime requires; our SECR thresholds guide sets out who qualifies.
Carbon offset strategy
A carbon offset strategy consultancy advises on residual emissions only — what remains after a company has reduced what it can.
Credible practice follows the mitigation hierarchy: cut emissions first, then offset the remainder with high-quality credits.
Carbon consultancy vs carbon software
The two routes suit different stages of maturity.
| Dimension | Carbon consultancy | Carbon software |
|---|---|---|
| Best for | First footprint, complex Scope 3, assurance | Repeatable annual measurement |
| Methodology | Expert-led, bespoke | Built-in GHG Protocol + DESNZ |
| Cost shape | Project / retainer | Annual licence |
| Builds capability | Limited | Yes |
| Typical sequence | Establish baseline & method | Run the year-on-year cycle |
A common pattern: a carbon consultancy sets the baseline and methodology, then carbon reporting software runs the annual cycle in-house.
How to choose a carbon consultancy
Check methodology first: the footprint should follow the GHG Protocol3 and use current DESNZ conversion factors1.
Confirm the consultancy can deliver the compliance outputs you need — SECR, UK SRS S2 — and that any offset advice follows the reduce-first hierarchy.
Ask for an auditable methodology and data trail so the footprint can later support assurance.
Frequently asked questions
What does a carbon consultancy do?
A carbon consultancy measures and helps a company manage its greenhouse-gas emissions: it builds a Scope 1, 2 and 3 carbon footprint using the GHG Protocol and DESNZ conversion factors, supports SECR and UK SRS S2 reporting, and advises on reduction and offset strategy.
What is a carbon footprint consultancy?
A carbon footprint consultancy specialises in the measurement step — collecting activity data, applying emission factors, and producing an auditable Scope 1, 2 and 3 inventory. It is the foundation for SECR compliance, UK SRS S2 disclosure, and any net zero target.
What does a carbon compliance consultancy help with?
A carbon compliance consultancy focuses on meeting UK regulatory obligations: Streamlined Energy and Carbon Reporting (SECR) in the Directors' Report, ESOS energy audits, and the climate disclosures of UK SRS S2. It ensures the figures are calculated and presented in the format each regime requires.
How does a carbon offset strategy consultancy work?
A carbon offset strategy consultancy advises on residual emissions only — after a company has reduced what it can. Credible practice follows the mitigation hierarchy: cut emissions first, then offset the remainder with high-quality credits, and disclose gross and net emissions transparently rather than claiming offsets reduce the gross footprint.
Do I need a carbon consultancy or carbon software?
Software is best for repeatable, year-on-year measurement; a carbon consultancy is best for the first footprint, complex Scope 3, and assurance readiness. Many UK companies use a consultancy to establish the baseline and methodology, then carbon reporting software to run the annual cycle.
