Disclosure-grade carbon programmes for enterprises.

The era of self-declared net-zero is over. CSRD, ISSB S2, SEC climate rules, UK SECR, and SBTi all require granular, audit-grade emissions data and a defensible transition plan. CAS builds the underlying data infrastructure first — supplier engagement, activity data pipelines, emission factor management — then layers on the strategy: science-based targets, marginal abatement cost curves, and a residual-emissions plan that uses high-integrity removals where reductions genuinely cannot. UK quoted companies, large unquoted companies and LLPs in scope of SECR receive a dedicated workstream — see /services/secr — so the same dataset satisfies the Directors' Report, CSRD ESRS E1, ISSB S2 and SBTi simultaneously.
