Category Standard

CarbonChain is a verifiable, high-impact Series A company (YC S20) providing essential carbon accounting for heavy industries. External search confirms significant traction ($24M+ funding, enterprise clients like Societe Generale), high real-world utility, and strong market relevance. However, the submission itself was of extremely poor quality, containing false claims regarding reach ('everyone') and traction ('most people'), and missing data. The final score reflects the project's strong verified fundamentals (Series A scale), heavily penalized by the low-quality submission.

Description
CarbonChain was born in 2019 with a mission to tackle climate change by decarbonising global supply chains. Our products offer quantitative and actionable insights to reduce greenhouse gas emissions in the supply chains of the world’s most polluting industries — oil \u0026 gas, mining, metals, minerals and agriculture — responsible for 50% of global greenhouse gas emissions. Our leadership team has deep expertise in commodities, supply chain management and data science, having worked for Amazon, Rio Tinto, Boston Consulting Group, UBS and more. CarbonChain is a proud member of ResponsibleSteel and is supported by the UK government’s innovation arm, InnovateUK, the NatWest accelerator and the London Business School Incubator. We graduated from Y Combinator as part of the Summer 2020 batch.
