Kill the ESG stack. Keep the number your CFO trusts.

In one platform: your carbon accounting tool (Scope 1/2/3), your disclosure and reporting tool (CSRD/ESRS, ISSB, GRI, TCFD, CDP), your supplier survey portal, your climate-risk model (double materiality, physical and transition risk) and the spreadsheets stitching them together. It also reduces reliance on a generalist consultant retainer, because the methodology, audit trail and history live in the platform and compound year on year. Everything runs on one data model with one audit trail - so the same activity data is entered once and flows everywhere.

Carbon-only tools calculate a footprint but leave you to report and interpret it. Disclosure-only tools format a report but do not own the data underneath it. ESG:ONE does both and more: it owns the carbon, Scope 3, supplier, materiality and risk data; maps it once to report across every framework; drafts the disclosure with AI; and then goes one step further - QuantESG Analytics translates it into P&L impact, cost of capital and valuation. It is the difference between reporting your emissions and knowing what they are worth.

No. The AI does three specific jobs, grounded only in your own data. It extracts activity data from invoices, utility bills and supplier LCAs into scored emission lines (about 80% less manual entry), matching a factor from a library of 140,000+. It drafts CSRD, ISSB and GRI narrative with every sentence traceable back to a number or document in your platform. And it runs compliance evidence scans that combine deterministic checks with an AI pass grounded only in your own policies, risks and actions. AI advises; a human always records the final verdict; everything is traceable and tenant-scoped.

QuantESG is the financial layer that pairs with the platform and runs on the same audited data. It translates your ESG performance into P&L impact, cost of capital and company valuation, and business-cases each initiative by ROI and scenario - the answer to the board's "what is it worth?" that carbon-only and disclosure-only tools cannot give. Many clients start with ESG:ONE and add QuantESG when the CFO asks for the ROI number. It is included at the Enterprise tier and priced on request.

All 15 GHG Protocol categories, upstream and downstream, with supplier portals and surveys (automated reminders included), AI extraction from invoices, utility bills and LCAs, spend- and activity-based calculation across 140,000+ factors, and PCAF-style data-quality scoring on every figure - so you can start with spend-based estimates and upgrade the biggest categories to supplier-specific primary data over time. On reporting, it covers CSRD/ESRS (including double materiality), ISSB (IFRS S1/S2), GRI, TCFD, CDP and custom frameworks. Map each data point once and the same audited number flows to every framework.

Most clients are live in about three weeks - onboarding, data migration and configuration are included in the licence, with no separate setup fee, and AI extraction removing 80%+ of the manual entry is what makes that timeline realistic. Before you commit, you can run a 30-day pilot on your own data, scoped up front to one framework, one facility or one supplier survey. Starter is from £3,000/year and Professional from £15,000/year; Enterprise - which adds QuantESG financial impact, portfolio ESG and custom frameworks - is tailored to scope and provided on request, with a fixed annual quote within 24 hours of a short sizing call.
