Aetium is a digital service that calculates and certifies CO2 reductions. We make it simple to register projects that reduce net CO2 emissions like solar panels, electric vehicles, forests and trees. Via our digital platform, we empower individuals and organisations to be recognised for their climate actions. Verified CO2 reductions are converted into Aetium TCUs (Tonne CO2 Units). TCUs are an accurate and credible digital instrument that can be traded or retired, offering a tangible way to recognise and reward CO2 reductions.
Aetium is a place where people and businesses take genuine action on climate change. To join, you must be either reducing CO2 emissions, or supporting the people that do. Using technology, we provide a comprehensive, independent solution that measures and certifies CO2 reductions - and the mechanism to trade and retire those CO2 reductions. We provide a transparent framework that promotes and rewards the reduction of CO2 from the atmosphere.
Established in Melbourne, Australia, Aetium's mission is to support people who are lowering CO2 emissions. We recognise the cost and effort made by people who install solar systems, drive electric vehicles, and those who actively protect and rehabilitate forests. Reducing CO2 emissions represents arguably our greatest global challenge. Instead of telling people what NOT to do, we focus on the actions that can be taken to improve the situation. Using the power of technology, we securely track and verify CO2 reductions. Our regulatory process is transparent, inexpensive and available to everyone.
We are an independent and impartial organisation that documents and certifies CO2 reductions. Our objective is to be trusted in all circumstances to tell the truth, to protect the environment, to call the numbers as they really are, and to be conservative with the facts. Every Aetium TCU is bound to proven principles, robust data and a digital framework that ensures our TCUs deliver the CO2 reductions committed.
Aetium utilises proven scientific calculation methodologies to accurately determine the CO2 effect of a given project over a retrospective 12-month period. Our calculation process undergoes periodic review to ensure we are utilising the latest best practice. Our patented technology platform allows us to cost-effectively document our multi-gated process, which includes:
In January 2024, Aetium became an endorsed member of the Smart Energy Council (SEC), which is an independent industry body representing the renewable energy, energy storage, electric vehicle, and renewable hydrogen sectors. In March 2025, Aetium was accepted as a signatory of the Australian Carbon Industry Code of Conduct, which is committed to developing an operating a carbon industry built on community trust, transparency, accountability, social and environmental integrity, in compliance with the law.
In addition, Aetium is currently undergoing multiple certification programs with government, industry associations and international certification programs. Whilst our technology is new, the science that underpins our modelling is undisputed. Additional certifications are expected to be added in the coming months.
Aetium's financial accounts are audited by KPMG.
A study across 17 advanced economies showed that 72% of people believed that climate change will harm them personally at some point in their lifetime (PEW Research Centre). And more than 80% of people were willing to make changes in how they work and live to reduce the effects of rapid climate change.
International consensus to achieve Net Zero emissions by 2050 [which would limit global temperature increases to 1.5°C above pre-industrialised levels] has been agreed by most of the world’s governments; however, current indications are that Global Net Zero by 2050 will not be achieved.
Despite the best efforts of many individuals, business and governments; delivering the step-change required to achieve Net Zero is often undermined by misinformation, politicisation, regionalisation and shorter-term business and national interests. A shift in the way we value and adopt CO2 reductions is required.
