We’re delivering a trusted, science-led approach to carbon measurement.

CSX’s purpose is to help develop a trusted carbon market, offering land managers a fair return for environmental management and businesses a transparent, verified carbon offset.

CSX was established in January 2020 by Andy Howard and Edward Milbank, entrepreneurial land managers and woodland creators, frustrated by the existing voluntary carbon market mechanisms. They saw that new technologies could be integrated and utilised to deliver integrity to the scaling of private sector investment into Nature Based Solutions.

Brexit meant the loss of the CAP funding mechanism, and the focus shifting towards habitat restoration. Andy and Edward recognised that land managers could use technology to collect and analyse the data necessary to provide an accurate measurement of carbon sequestration. Moreover, that same data could provide corporates with the audit and verification necessary to underpin an ESG investment.

Meet the team

Andy Howard

CEO and Co-Founder

Andy's early career encompassed insurance underwriting, and then 15 years in the packaging industry, where he ultimately became the Sales Director for the main supplier of own brand tapes into the UK retail sector. Andy’s packaging industry career included responsibility for accounts such as Coca-Cola, Hovis and Nestle, and restructuring and managing the UK operations of a Dutch multi-national company. Since 2011 (together with Edward Milbank) he has been the co-Founder & Director of Pennine Biomass Ltd, Pennine Enterprises Ltd & Pennine Forestry Ltd. This group of companies has led the way in transforming the implementation of commercial afforestation projects in England, and Andy has been directly involved in informing DEFRA and Government on the development of tree planting initiatives in England. CSX was born from the founders’ experience of seeing inefficiencies in the current carbon market, and identifying an opportunity to help accelerate the drive towards a greener economy. CSX provides the technical infrastructure that businesses and landowners need to measure carbon and other natural capital accurately from Earth Observation data. We help our partners make important ecological decisions with certainty and confidence by providing a verifiable audit trail. The data we can provide on carbon sequestration gives much needed reassurance to everyone involved. In short, CSX exists to help businesses and landowners take control over their climate action immediately and to provide integrity and structure to that process.
