We answer your customer first. Then we look for the money.
Nemetan helps UK and Irish suppliers with the sustainability demands their customers send, from EcoVadis to Scope 3. If you want it, we then look in the same evidence for savings.
Mike Kelly CDir
Mike has spent more than 25 years building companies and learning the same lesson each time: the best opportunities are usually the ones nobody thought to look for.
Board-level training in risk and a banker's view of sustainable finance mean he reads a supplier questionnaire the way your board and your lender will.

Built on evidence of what has actually paid off
Clients get the assessment they came for. Those who want more can ask what else their data shows, the way a good accountant looks past the statutory accounts to where the margin is leaking. That draws on the Nemetan evidence base: more than 2,000 verified projects from real companies, each with documented results.
A project only gets in if it passes five tests:
- A named company carried it out.
- It was fully implemented, not pledged or piloted.
- It delivered a measured business result, such as a cost saving or new revenue.
- It delivered a measured environmental or social result.
- Both results came from the same decision.
Take Imperial College Healthcare NHS Trust, which saved £440,000 and 590 tonnes of CO2 by switching off computers left idle. One decision, a named organisation, two measured results. So when we suggest a supplier could cut packaging costs or deliver competitive advantage with a lower-carbon product, we can usually show a company that already did it.
Our relationship with EcoVadis
None. Nemetan is independent. We aren't an EcoVadis Accredited Consulting Partner, we don't sell EcoVadis subscriptions and we earn nothing from EcoVadis. We help suppliers prepare their evidence; EcoVadis analysts decide the score.
What we help with
EcoVadis assessments, science-based targets and Carbon Reduction Plans, ISO 14001 and ESOS. Not sure which applies? Start with our guide to sustainability requirements for suppliers.
We also run carbon literacy training for supplier teams, and our sustainable manufacturing guide shows manufacturers where the cost hides in their waste.
Research
Nemetan's research found large European companies report sustainability risks two to three times as often as opportunities (The Opportunity Gap, Kelly, 2026). Mike's writing has appeared in Illuminem, SustainabilityOnline and OneStopESG. See news.
Our guide to double materiality assessments explains how Risks and Opportunities should be identified, and where most companies stop short.
Where we work
Suppliers across the UK and Ireland that sell to large companies or the public sector. Mostly remote, with site visits where they help.
Questions about Nemetan
Where does the name Nemetan come from?
From the nemeton, a space set apart in the ancient Celtic world where a community's elders gathered to weigh hard questions and see clearly before they acted. You went there to think straight. Customer sustainability demands can feel like noise; Nemetan is meant to be that clear space.
What does the Nemetan logo mean?
The mark is an open green ring with a blue dot at its centre. The open ring is an O left unfinished: the opportunity that sustainability work so often leaves incomplete. Green is the colour we use for opportunity throughout our work, and the dot is the point we put back at the centre.
Do I have to take the cost-saving review?
No. If you need an EcoVadis rating or a Scope 3 assessment, that is what you get, at a fixed fee. The look at what your data could save or earn is there if you want it, and only then.
What counts as a sustainability opportunity?
A move where the business benefit and the environmental or social benefit come from the same decision. Using less material lowers cost; a cleaner product delivers competitive advantage in a tender. A cost that only buys goodwill doesn't count, and neither does a risk avoided and dressed up as a gain.
How much of the work is automated?
Tools do the repeatable work, such as organising documents and matching precedents. Every finding you receive is checked and judged by a person, with its assumptions and uncertainties written down.
