(Sustainability & ESG)

ESG reporting software that can show its working

ESG reporting fails on evidence, not ambition. We build the collection, calculation and audit trail behind your numbers, so every figure in the report traces back to a meter reading or an invoice.

Sustainability & ESG

(Where the numbers come from)

Most sustainability reporting still lives in a workbook that one person understands. It works until an assurance provider asks how a figure was reached, which emission factor applied, and who approved the estimate used for the three sites that never returned their readings. Answering that reliably is a data engineering problem long before it is a reporting one.

So the first phase is usually an inventory: what data already exists, where it sits, how often it arrives, and how much of it is currently somebody typing figures from a PDF.

(What we deliver)

What ESG and sustainability software covers

The work divides into getting data in, turning it into figures with a method, and proving both to somebody sceptical.

  1. Automated feeds from building management systems, sub-meters, Modbus and OPC UA sources, fuel cards, fleet telematics and travel bookings — plus a tidy manual entry route for the sites that will never have an API. Gaps are flagged rather than silently filled.

  2. Activity data multiplied by the emission factor set you licence, with versioned factors so a restated prior year can be reproduced exactly. Scope 1 and 2 are mostly arithmetic done carefully; the value is in never losing which factor was applied when.

  3. Questionnaire portals for scope 3 categories, spend-based estimates where suppliers cannot yet answer, and a clear marker on every figure showing whether it is measured, estimated or extrapolated. Chasing non-responders is automated so your team is not doing it by email.

  4. Output structured for the GHG Protocol, CSRD and ESRS data points, GRI disclosures or CDP questionnaires as a practice, mapped once so the same underlying data serves several frameworks. Mapping changes as standards change, which is why it is configuration, not code.

  5. Site managers see consumption against their own baseline; the finance team sees intensity against revenue or floor area; the board sees the trajectory. Different audiences, one data model, no competing spreadsheets circulating by email.

  6. Every figure links to its source document, its calculation, its factor version and the person who approved any override. Changes are appended rather than overwritten, so a restatement is explainable months later.

(How we work)

How the work runs

Every engagement is scoped in phases, priced per phase, and reviewed with you at the end of each one.

  1. 01

    Discovery

    We map the problem, the systems around it and what a good outcome looks like, then scope the work in phases you can stop after.

  2. 02

    Design

    Flows, architecture and interfaces agreed before anyone writes production code.

  3. 03

    Build

    Two-week increments, a working environment you can open, and a demo at the end of each one.

  4. 04

    Testing

    Functional, performance, security and accessibility checks run through the build, not bolted on at the end.

  5. 05

    Launch

    Deployment, monitoring, documentation and the handover your team needs to run it.

  6. 06

    Support

    Fixes, updates and the next set of features, at an agreed monthly capacity.

(Why Team of Keys)

Why ESG software has to be built for scrutiny

A sustainability figure is only as good as the question it can survive. These are the design decisions that make that possible.

  1. 01

    Provenance on every number

    Click any total and reach the readings, invoices and factors beneath it. That single property is what turns a reporting tool into something an assurance provider can work with quickly.

  2. 02

    Estimates labelled as estimates

    Missing data gets an estimate with a stated method and a visible flag, never a quiet guess. Reports then show measured and estimated coverage separately, which is what most frameworks ask for anyway.

  3. 03

    Restatement without archaeology

    Factors, boundaries and organisational structure are versioned. When last year has to be restated after an acquisition, the system reproduces both the old figure and the new one.

  4. 04

    We build it; your assurer signs it

    This is software engineering and data work. Verification, assurance and accreditation come from a qualified provider, and we make their job faster rather than claiming to replace it.

  5. 05

    Designed for the standards moving

    Frameworks change every couple of years. Disclosure mappings sit in configuration your own team can edit, so a new ESRS data point does not require a development ticket.

(FAQ)

Questions, answered

A first release covering scope 1 and 2 for a defined set of sites is usually one build phase after a short discovery. Cost grows with the number of source systems, sites and scope 3 categories in play. Supplier portals and multi-framework mapping are normally scoped as later phases once the core data is trustworthy.

No. We are engineers, not an assurance body, and we hold no accreditation to verify a report. What we build is the data platform, the calculation trail and the evidence pack your auditor or assurance provider asks for — which is usually where the time and cost of assurance actually go.

Yes, and it is the normal starting point. The workbook is the specification: it encodes the boundaries, factors and judgement calls your team already makes. We reimplement that logic where it is sound, question it where it is not, and keep importing the sheets that genuinely have no better source.

Two routes, both visible in the report. A portal with reminders raises response rates for the suppliers who can answer; for the rest, spend-based or average-data estimates fill the gap with the method recorded against each figure. Coverage improves year on year, and the system shows exactly how much of it is estimated.

Discovery and the data inventory take two to four weeks. A working system for energy and fuel data across a defined site list typically lands within a few months, because the constraint is rarely software — it is getting access to meter data, utility portals and the people who hold the invoices.
