Carbon Re is developing a leading edge artificial intelligence platform, Delta Zero, which uses deep reinforcement machine learning to address complex process optimisation challenges within the foundation industries. Delta Zero will enable process plants to radically reduce carbon emissions and operational costs.


The Clean Growth Fund led our pre-seed round, and further increased their investment through our 2022 seed round. We have also bene ted from non-diluted equity for a R&D project through CGF’s combined investor grant programme with Innovate UK. This has enabled us to start to expand our focus from just cement into adjacent pollutive sectors like steel and glass manufacture. CGF has consistently been proactive in raising our company pro le and supporting our business development.

For us, having an impact driven investor backing the company is key – we know that our mission and values are fully aligned, and we look forward to a long and successful partnership together.
