Earthmark joins the National Climate Tech Accelerator to fast-track growth
Written by Jack Linnett (Co-founder & CEO)
The UK’s climate tech sector is entering an exciting new chapter — and Earthmark is proud to be part of it.
Earthmark has been selected to join the National Climate Tech Accelerator (NCTA), a nationwide programme launched by Barclays Eagle Labs and Sustainable Ventures to supercharge the growth of the UK’s most promising climate and sustainability startups.
The NCTA combines the reach of Barclays Eagle Labs’ entrepreneurial network with Sustainable Ventures’ decade-long track record of scaling climate tech success stories — supporting over 1,000 startups, creating 7,000 green jobs, and enabling £1.2bn in climate investment to date. With Barclays committing up to £500m in climate tech investment by 2027, the Accelerator is set to become a cornerstone of the UK’s green innovation ecosystem.
For Earthmark, joining the NCTA represents a powerful opportunity to accelerate our mission: helping ecommerce retailers and marketplaces build credible, actionable sustainability strategies grounded in data transparency and real-world impact.
The Accelerator will provide unparalleled access to mentorship, technical support, investor networks, and strategic partnerships — enabling us to scale faster and expand our capabilities across the UK and beyond.
“We’re building the trusted data infrastructure for sustainable commerce. Joining the NCTA gives us a platform to collaborate with like-minded founders, leverage world-class support, and amplify our impact as the climate tech economy matures.”
— Jack Linnett, Founder & CEO, Earthmark
As the global push for net-zero accelerates, initiatives like the NCTA are critical in transforming ambition into execution — helping companies like Earthmark deliver tools and data that drive meaningful change in how the economy measures, reports, and reduces environmental impact.
This is an exciting chapter for Earthmark and for the broader climate tech community. We’re ready to contribute, collaborate, and help shape the systems that define the next decade of growth.
