Carbon credit brokerage · London · Dubai
1 credit = 1 tCO₂e · measured, certified, transferable
Carbone Zero brokers the sale and purchase of verified carbon credits across Australia, the United Kingdom, North America and beyond, backed by a certification arm that has been measuring abatement for over twenty years.
What we do
We broker carbon credits sourced from regulated and independently verified programmes: Australian ACCUs, UK woodland units, US registry credits and more. Sellers reach real buyers; buyers get credits with a paper trail they can defend.
How brokerage worksMeasured emission reductions become certificates of ownership under our own published, version-controlled quantification protocol. These are originated and certified by us, and labelled that way, never blended with third-party verified units. One credit, one tonne, one retirement.
The methodologyThree levers do the work: profile reset, asset optimisation and resource recovery. They cut operating costs and emissions with no capital outlay, and the abatement is then certified. Clients have banked documented savings.
The three levers
Metered on site, long before it reaches a ledger.
On the record
certified and issued against a single solar project, one credit per tonne
identified across client engagements — savings delivered and new revenue not yet implemented, counted separately
start of our longest continuous client relationship, still running
emission scopes measured, across waste, water, gas, electricity, fuel and telecoms
Certified tonnage is taken from the certificate of ownership issued for that project. Financial figures are identified savings and new revenue across named client engagements, drawn from client ESG reporting held on file. Savings and revenue are counted separately, never combined into a single return, and figures identified but not yet implemented are recorded as such.
We don't broker credits we can't trace to a registry entry, a certificate or a regulator. That rule has cost us transactions. It's also why buyers come back.
The chain of proof
One credit. One tonne. Measured before it is claimed, or the credit doesn't leave the ledger.
Emissions are baselined across Scopes 1 to 3, covering electricity, gas, waste, water, fuel and telecoms, before anything is claimed.
Abatement is delivered through operational change, not promises: contracts reset, assets optimised, waste streams recovered.
Measured tonnes become certificates of ownership under a published, version-controlled methodology, recording the project, the period and the quantification behind each credit.
Credits are sold to buyers who need them, or retired against the holder's own footprint. Either way, the paper trail survives scrutiny.
Where the credits come from
Every credit we originate traces back to hardware you could stand next to. Our largest issuance to date — 9,630 tonnes — came from solar canopies built over a car park that was already there.
Panels mounted over existing parking. No land acquired, shade for members, and the meter reads the same either way. This is the project behind our 9,630-tonne certificate.
Club, hotel and retail roofs carrying arrays sized against actual consumption — verified by climbing onto the roof, not by measuring a satellite photograph.
Standalone arrays on unproductive land beside the sites they serve. Smaller than a utility farm, and far easier to meter honestly.
Where the tonnes are largest and the evidence is simplest: every megawatt-hour is metered before anyone has to argue about it.
Container deposits, used cooking oil bound for biodiesel, glass and wax-coated cartons diverted from landfill. One club cut 0.96 tonnes from wax cardboard alone.
Freezers, HVAC and back-up generators that step back for fifteen minutes when the grid is stressed, six to nine times a year. The gas peaker never runs.
