Production carbon software, built by practitioners.
Registries, MRV pipelines, ESG dashboards, compliance engines, marketplace venues, and carbon intelligence platforms — engineered with the security, observability and audit posture institutional users require.
Indicative bands — final scope confirmed after a 20-minute discovery call.
Practice positioning.
Carbon software is built differently. Every value in the system has provenance — instrument, methodology, factor, version. Every state change has a counterparty, a timestamp and an immutable log entry. Every external claim must reconcile to a serialised unit in a registry. CAS's engineering practice is staffed by people who have shipped registries, MRV stacks and disclosure platforms in production. We do not retrofit generic SaaS into carbon use cases — we build to the integrity model from the first commit.
How CAS delivers.
Domain modelling
Model the unit, the registry, the methodology, the inventory and the disclosure surface as first-class entities — not afterthought tables.
Reference architecture
Choose between hosted, on-prem and hybrid deployments; design data residency, key management and disaster recovery.
Build & integrate
Ship in vertical slices: registry primitives → workflows → public APIs → operator UI → public transparency surface.
Hardening & handover
Penetration testing, observability, runbooks, training, and a phased handover to the client's operations team.
