A carbon-neutral path for London businesses

Zero Carbon UK is being built for companies in London and Greater London that want a straightforward way to count their yearly emissions, buy credits, and retire — or burn — them in their name, with a certificate to show for it.

For London businesses

A carbon-neutral path for London businesses

The first credits are only there to get the platform started. The lasting idea is a loop: money from making businesses carbon-neutral is put back into new UK green projects, which can then generate UK credits and gradually take the place of the international supply.

This is a planned platform, not a government scheme, and it is not endorsed by the Mayor of London or the Greater London Authority. It is for voluntary use and for pilots.

  • Calculate with official 2026 UK Government factors
  • Retire credits in your organisation’s name
  • Reinvest revenue through a planned UK Green Fund

The reinvestment loop

How your money works

The centre of the model: a loop from your purchase to new UK credits. Illustrative, not a live fund.

When a business buys credits through Zero Carbon UK and we retire them, the plan is that the revenue is reinvested, not taken out as the end of the story. It is intended to go into a UK Green Fund and from there into new UK projects — for example woodland, peatland, solar and building retrofit. Those projects can, in time, generate UK carbon credits, which can be retired for later customers and slowly replace the international credits used at launch.

  1. 01 You calculate your footprintA simple yearly estimate for your business, using official UK Government figures in the calculator.
  2. 02 You buy credits, and we retire themCredits are bought to match the tonnes you still need to cover, then retired — burned — so they cannot be sold again.
  3. 03 Revenue goes into a UK Green FundThe plan is that all revenue from selling credits and helping companies become carbon-neutral is reinvested through this fund.
  4. 04 The fund backs new UK projectsIllustrative types include woodland, peatland, solar and retrofit. No specific projects, sites or amounts are listed here yet.
  5. 05 New UK credits come back aroundAs those projects generate credits, they can be retired for future businesses, gradually replacing the international supply used to start the platform.

Existing international credits, including a planned REDD+ holding, are only to bootstrap the business. Registry, project and vintage details will be published on this page once they have been independently confirmed. Until then, please do not rely on unverified claims about those credits.

From estimate to certificate

How it works for your business

  1. 01

    Calculate

    Tell us what your business uses — vehicles, energy, travel and the rest — and get a yearly total in tonnes of CO2, plus how many credits you would need.

    Planning tool
  2. 02

    Buy credits

    When sales open, you will be able to buy credits to cover that total, or a part of it you choose. Reduce what you can first; buy credits for what is left.

    Not on sale yet
  3. 03

    Burn and retire

    Credits are retired in your organisation’s name so they cannot be used again. This is often called burning them.

    Once sales open
  4. 04

    Get a certificate

    You receive a record of the tonnes retired. As registry details are confirmed, certificates will point to the public retirement record.

UK Business Carbon Calculator

A working draft, already using official UK Government 2026 conversion factors.

You can try a simplified UK business carbon calculator now. It is a planning tool, not a formal audit, and it does not sell or retire credits yet.

The path to UK credits

Illustrative phases only. No launch dates, volumes or named projects are set here. The aim is to start with verified international credits, then grow a UK project pipeline, then reach a point where most credits retired through the platform come from UK projects.

Launch

Businesses in London and Greater London calculate, buy and retire verified international credits, used only to bootstrap the platform.

Illustrative phase
A growing UK pipeline

Revenue is reinvested through the UK Green Fund into new UK green projects, such as woodland, peatland, solar and retrofit.

Illustrative phase
Majority UK credits

Credits generated by those UK projects make up most of what is retired, gradually replacing the international supply.

Illustrative phase

London first, then the UK

Why London

We are starting in London and Greater London because it is a dense business community, and because the city has already set a clear climate aim. The Mayor of London has set a target for London to be net zero carbon by 2030. That target, and the preferred “Accelerated Green” pathway, are set out by the Greater London Authority.

Zero Carbon UK is not part of that official programme, and it cannot on its own deliver the 2030 target. Reducing emissions at source still comes first. The offer here is a voluntary way for London businesses to measure what remains, retire credits transparently, and channel spend towards a future UK project pipeline — with a later expansion across the UK.

What we will publish

Transparency and the registry

When credits are sold and retired, you should be able to check them on a public registry. Those details are not confirmed yet, so they are left blank on purpose rather than filled with claims we cannot stand behind.

Nothing here is a live sale Until registry, project and vintage details are independently confirmed, and until purchases are open, this site does not offer credits for sale and does not issue certificates. The calculator is a preview only.

Pricing

Live prices will be published here before any sale begins. They have not been set yet.

The calculator already lets you try an illustrative figure of £95 per credit. That figure is a worked example from the business plan, not a market tariff and not a price you can pay today.

Local and national government

For councils and government

London and Greater London are the intended first test bed, with a later rollout across the UK. The platform is designed so a council, combined authority or government department can see how a simple calculate–retire–reinvest loop could work for businesses in their area.

If you work in local or national government and want to discuss a pilot, please use the waitlist below and say so in the note.

Voluntary, or agreed pilots

It is offered for voluntary use and for agreed pilots, not as a tax or a licence condition.

Not a council bylaw

Making this kind of offsetting compulsory would need national legislation. Councils cannot mandate it through bylaws.

A planned UK Green Fund

The UK Green Fund is intended to put revenue into UK projects, so later credits can be closer to home.

No claimed backing

We will not claim official backing unless a public body has agreed it in writing.
