About CarbonChain

The fight against Climate Change is evolving rapidly. Climate tech is changing. The first wave was reporting. The next is treating carbon the way companies treat money:as a way todecide what to buy, who to sell to, and which incentives to claim.

Around the world, carbon is becoming a condition of trade. Border taxes, free allocations, green premiums, cheaper capital. It looks a lot like the post-warrebuild:governments put capital and tax incentives on the table, and the companies that could keep the books moved first. The missing piece then was bookkeeping. The missing piece now is the same, carbon accounting.

CarbonChainis that bookkeeping. We turn messy, real-world supply-chain data into numbers a trader, a sustainability lead, or a CFO willactually use.

We want people who are agents of change, who feel the impact of climate change and know there is no way around it to create a better future for every being.

People who know the customer is the truth of how a company thrives. People who treat data as the fuel for how fast society can change. People who use AI to accelerate the cause for good by working through an AI lens first to automate repetitive tasks and analyse data. Finally, people who enjoy working with people.

Our Product

We help the world's largest commodity producers and traders measure and cut emissions, with verified primary data where we can get it and defensible defaults where we cannot. The platform turns operational and supplier files into decision-grade carbon and compliance insight: sourcing, CBAM, product and corporate footprints, reporting customers and regulators will stand behind.

We organise carbon accounting around the user in four contexts at once:

• Immediate: the tools in front of them
• Internal: how they work with colleagues
• External: how they work with suppliers and customers
• Societal: how they work with society, governments, and disclosing bodies

The data we hold is only useful if it makes all four of those jobs easier.
