About
Sustainability infrastructure for the businesses that need it most.
Mid-sized companies are being asked to meet enterprise-grade disclosure standards without enterprise-grade tooling. GreenSphere closes that gap.
What we believe
Sustainability reporting is becoming what financial reporting became thirty years ago.
Not a project. Not a deliverable. A category of operational infrastructure that every credible business runs on — structured, auditable, and continuously maintained. The companies that thrive in the next decade will be the ones that treated sustainability data the way they treated their financial ledger.
How we build
Engineered as infrastructure, not as a reporting tool.
Four principles shape every decision we make.
Built on standards, not opinions.
Anchored in GRI, IFRS S1 & S2, and the GHG Protocol. We implement what regulators, auditors, and investors already trust.
Methodology over marketing.
Every emission factor is sourced from DEFRA 2025, EPA 2025, or EMBER. Every figure carries a full audit trail.
Infrastructure, not features.
Extensible primitives — data models, calculation engines, reporting rails — that absorb new frameworks without forcing a migration.
Designed for the businesses that have been overlooked.
Built from the operating reality of mid-sized teams: limited internal sustainability headcount, real budget constraints, and deadlines that arrive whether the business is ready or not.
What we operate against
The standards regulators, auditors, and investors already rely on.
GreenSphere produces audit-ready disclosures with full data lineage and methodology transparency — the structural rigour required by procurement teams, compliance reviewers, and external auditors.
