What is Sylvera anyway? ‍👩‍👨🌳

Sylvera provides carbon data for genuine climate impact. Our mission is to incentivize investment in real climate action. 

Purchasing credits through the carbon markets is one of the most established and scalable ways to channel finance from the private sector to effective climate solutions and work toward societal net zero. Unfortunately, the voluntary carbon markets have been plagued with mistrust and a lack of effectiveness since they’ve emerged – until Sylvera. 

To help organizations ensure they're making the most effective investments, Sylvera builds software that independently and accurately automates the evaluation of carbon projects that capture, remove, or avoid emissions. With Sylvera's data and tools, businesses and governments can confidently invest in, benchmark, deliver, and report real climate impact. 

Our team is made up of leading minds in climate change from scientists to policy, finance and carbon market experts. We work in partnership with scientific organisations, universities, governments and think tanks to develop and test rigorous and holistic ratings methodologies, leveraging the latest technology. Founded in 2020, Sylvera has 150+ employees across the world with offices in London, New York, Belgrade and Singapore. We’ve raised over $96million from leading VCs like Balderton Capital, Index Ventures and Insight Partners to date.
