Carbon accounting and sustainability reporting

Carbon accounts you can trust and explain

Most organisations struggle not because they lack commitment to reducing emissions, but because their carbon data is incomplete, inconsistently measured, or not structured for the audiences that matter: regulators, investors, boards, and supply chain partners.

We build carbon inventories with technical rigour and practical clarity. Every engagement starts with understanding your business model and data landscape. We then work systematically to produce carbon accounts you can stand behind in any forum.

Carbon accounting is the measurement foundation that feeds regulatory disclosure. If your priority is reporting compliance, see CSRD advisory, BRSR advisory, or UK climate reporting. Both services can run in parallel or sequentially depending on where you are in your carbon journey.

FAQs

Common questions about carbon inventories, GHG Protocol methodology, regulatory compliance, and net zero roadmaps.

What is included in a carbon inventory?
A complete GHG inventory covers Scope 1 (direct emissions), Scope 2 (purchased energy), and Scope 3 (value chain emissions) aligned with the GHG Protocol Corporate Standard. We handle data collection, activity mapping, emissions factor application, and produce a structured, defensible carbon baseline suitable for investors, regulators, and public disclosure.
Which regulatory frameworks do you cover?
We provide compliance guidance across TCFD, CSRD, UK SECR, and ISO 14064. Disclosures are structured to be accurate, consistent, and ready for third-party verification.
How do you handle Scope 3 value chain complexity?
We take a practical, phased approach. We prioritise material Scope 3 categories, define data ownership, design supplier data collection workflows, document methodology and assumptions, and improve data quality cycle by cycle through governance.
Can you help us set science-based targets?
Yes. Once a carbon baseline is established, we develop SBTi-aligned science-based targets, identify priority reduction levers across your operations and value chain, and produce a costed, credible net zero roadmap your leadership can act on.
Who is this service designed for?
This service is designed for SMEs and mid-market businesses building their first carbon inventory, regulated businesses facing SECR, CSRD, or other obligations, organisations under investor or supply chain scrutiny, and companies working toward SBTi or net zero commitments.
How do you ensure the carbon accounts are audit-ready?
Every engagement produces structured methodology notes, clear evidence trails, validation checks, and documentation standards so your carbon accounts can withstand scrutiny from auditors, investors, or regulators. We also prepare clients for third-party verification readiness where required.
Where should we start?
Start with a discovery and scoping session. We review your business model, existing data sources, and reporting obligations, then propose a practical carbon inventory and reporting roadmap with clear timelines and deliverables.
