Net Zero & Sustainability

Corporate sustainability functions live with the consequences of how Scope 2 is reported, how certificates are procured, and how decarbonisation pathways are documented. Auditors, investors, and rating agencies scrutinise the work. So do regulators.

Arc advises sustainability teams on the substantive choices: which certificates to procure, which reporting methodology to apply, what to assure and to what standard, and how the renewable energy investment programme supports the disclosed pathway. The deliverable is structured to be defensible under BDO or Big Four assurance.

Sustainability functions sit between the executive committee that wants ambitious targets and the auditor who wants documentation. Arc writes for both audiences in the same deliverable: bold enough for the strategy paper, structured enough for the assurance file.

We have advised on Scope 2 programmes across FTSE-listed corporates and have built the methodology notes that survive BDO, KPMG, and PwC review. The corpus-knowledge work, the registry account setup, and the cert market research are all documented internally so the engagement does not start from scratch each time.

Arc is independent of any certificate marketer, registry, or technology provider. That independence is the basis on which our advice is worth paying for.
