Our verdict on ESG:ONE
ESG:ONE brings sustainability data, emissions accounting, supplier management and framework reporting into a cloud platform for small, mid-market and enterprise organizations. It covers Scope 1, 2 and 3 emissions, supplier questionnaires and portals, double materiality assessments, and reporting against CSRD/ESRS, TCFD and custom frameworks. That breadth suits teams coordinating disclosures across carbon data, suppliers and business entities; it may be more than needed for organizations seeking only a narrow carbon calculator.
Scope 3 is a particular area of depth: Professional and the separate Scope 3 First package cover all 15 GHG Protocol categories. Scope 3 First is listed at £79 per month, billed annually, and includes spend-, average-, hybrid- and supplier-specific calculations, AI factor matching, a branded supplier portal, PCAF data-quality scoring and CSRD Scope 3 outputs. Professional adds full Scope 1–3 emissions, supplier due diligence, CSRD reporting, double materiality, AI data extraction and assurance-ready exports. Starter instead centers on Scope 1 and 2 accounting, standard templates, supplier questionnaires and EcoVadis responses. The published starting price for the platform is £3,000 per year; Enterprise is priced by quote.
For organizations preparing evidence for review, audit trails, data-quality scoring and PDF/XBRL exports support an assurance-oriented workflow. AI extraction can draw information from invoices, utility bills and supplier documents, while integrations include SAP, Oracle, Microsoft Dynamics, Workday, ERP and HRIS platforms, facility-management tools, utility providers and travel platforms. Enterprise adds custom frameworks, multi-entity consolidation, API access and integrations, QuantESG Analytics, a dedicated success manager and SLA guarantees. Choose ESG:ONE when reporting spans suppliers, multiple frameworks or entities and assurance outputs matter; a smaller team with simpler needs may prefer a narrower tool. Pricing starts at £3,000 annually, with the separate Scope 3 First option priced differently.
