Software Engineer, Data Engineer, Data Scientist

Allied Offsets has a unique mission: combine technology, data, and finance to bring radical transparency to carbon offsetting. We do this by creating innovative data products that help to improve transparency in the market. With 30,000+ projects in our database including details about the project, carbon credits, buyers, retirements, news, brokers, resellers, prices, forward curves and much more. Our current clients include corporations, financial institutions, brokers, academia, consulting firms, public sector entities, and research organizations.

Carbon offsetting is becoming increasingly popular as companies and individuals around the world take a more active role in mitigating climate change. However, the market is very fragmented with (until now) no central registry for all the projects, making it difficult to know what the projects are, and how they compare with others. Our database allows a wide variety of industry actors to access information on projects across all registries, in order to make the market more transparent and available to all.
