By recreating the building blocks of our everyday economy, we will create the multiplier effect that we need now to make a real impact faster.
Cocoon
To decarbonise the world, we are going to have to build a lot more. This means we will need more steel and cement over the next 40 years than ever before. However, these two materials represent 15% of global emissions. We’re capturing CO₂ into industrial waste and upcycling this into a green cement alternative to decarbonise the steel and cement industries. This mineralisation process has been the focus of our Chief Scientist Officer’s research and we’re now commercialising it at scale.
Cbamboo
Cbamboo’s mission is to drive firms to decarbonise their supply chains and minimise their carbon border taxes. Our software platform will keep companies compliant with the EU’s Carbon Border Adjustment Mechanism, a new law applicable to EU importers in dozens of industries.
We are developing AI tools to analyse embodied carbon, forecast CBAM costs, model the knock-on effects on prices, and report back on resulting sustainability metrics. Our products will address the needs of importers, who pay CBAM directly, as well as their suppliers and their customers. As carbon border taxes evolve and spread worldwide, Cbamboo plans to be at the forefront of helping firms to integrate these taxes into their management decisions.
Climate-i
Fluorinated gases (F-gases) are manufactured chemicals which play a critical role in cooling, refrigeration and electricity transmission globally. However, most are extremely potent greenhouse gases, thousands of times more powerful than CO2 and making up a similar share of emissions as global aviation. Climate-i is building technology to predict equipment failure, improve system reliability and efficiency and reduce the carbon footprint of cooling, refrigeration and electricity transmission. Our team is experienced in the development of AI/ML software, IoT systems and sensor hardware, allowing us to seamlessly integrate hardware and software as a service.

Cercula
As the construction space continues to be hit with new regulations around Carbon and environmental preservation, developers and contactors are being asked increasingly for their carbon data. As demand for this data increases, people are turning to Environmental Product Declaration providers to access emission factors. However, this data is disperse and in many cases in an unstructured form. There is also often a diverse bulk of material data, both before a building is designed, and after materials have been purchased for a project. The result is a long pen-and-paper process, heavy on laborious data processing, prone to human induced errors. Disruptions to construction planning processes can be expensive at the least, and fatal to the project at the worst.
Kestrix
Kestrix is using mass drone image capture and AI to unlock building portfolio decarbonisation at scale.

Kita
Kita’s vision is to be the world’s first carbon insurer, de-risking carbon removal solutions to accelerate their ability to scale.
The climate crisis requires carbon removal solutions to remove carbon from the atmosphere. Many carbon removal solutions rely on revenue from selling carbon units on the voluntary carbon markets. However, these units lack tailored insurance products for their key risks, particularly under-delivery on pre-paid contracts.
Kita removes this “carbon delivery risk” from sellers and buyers in the market, using insurance products that guarantee the quality and delivery of carbon units and carbon removal solutions.
