One place for your ESG.

Companies come to us because their energy bills are too high, a customer sent an ESG questionnaire, or a bank wants a carbon report. We handle all three with the same data.

Stop overpaying. Electricity, gas, water and waste bills are tracked month by month. We flag the bills that look wrong and show you when your electricity contract costs more than current business offers in Ireland.

  • Cost and usage per site, per month
  • Missing or unusual bills flagged
  • Contract compared with the market (Ireland)

We check each supplier for country, environmental and reputational risk, and collect their data through a simple portal. Their real data then replaces estimates in your footprint.

  • Risk check on every supplier, with sources
  • Questionnaires sent and chased for you
  • Their real data replaces estimates in your Scope 3

Scope 1, 2 and 3, calculated from the same bills and invoices, with a VSME or GHG Protocol report ready to send.

  • Scope 1, 2 and 3 to the GHG Protocol
  • VSME report for EU value-chain requests
  • Net Zero targets and a reduction plan

Questions, answered.

What are Scope 1, 2 and 3?

Scope 1 is what you burn directly (gas, fuel, company vehicles). Scope 2 is the electricity and heat you buy. Scope 3 is everything else in your value chain: purchased goods, transport, business travel, commuting, waste. For most companies, Scope 3 is the biggest part.

What do you need from us?

Whatever you already have: energy and fuel bills, travel and purchase invoices, and any spreadsheets. We give you simple templates for anything missing, and we only ask for what your framework actually needs.

Will my bank, investor or customer accept the report?

Reports follow the GHG Protocol and the VSME standard, and every figure links back to its source document and emission factor, which is what reviewers look for. If someone asks for a specific format, tell us on the call.

What does “one place for your ESG” cover?

Energy and utility bills, supplier checks and questionnaires, your carbon footprint, Net Zero targets and the reports that go with them (VSME, GHG Protocol). It all runs on the same data, so you only send your documents once.

Do you work outside Ireland?

Yes. We work with companies anywhere, fully remotely. Each site is calculated with emission factors for its own country, and reports follow the GHG Protocol, which is used worldwide. EU companies can also get a VSME-format report. Electricity contract comparison currently uses offers in Ireland.

Do we have to use the software?

No. With Carbon Report and Carbon Partner, our team does the work. Dashboard access is included so you can explore your numbers whenever you like.

Where does the agent fit in?

The agent reads your documents, extracts every line and proposes the right emission factor. Our team checks the results before anything reaches your report. It speeds the work up; it never makes the call alone.
