Microsoft has agreed to purchase 1.1 million tons of carbon removal credits from Hafslund Celsio, an energy from waste (EfW) and carbon capture and storage (CCS) firm which is set to be delivered over a ten-year period, will be generated by a CCS project under development at the site of Norway's largest EfW plant, Celsio, in capital city Oslo.

“The agreement with Microsoft is a significant contribution to the commercial success of Hafslund Celsio’s carbon capture and storage project. Microsoft’s purchase is a strong recognition of our CCS project and highlights the crucial role of the waste-to-energy sector as a credible provider of permanent carbon removals,” said Martin S. Lundby, CEO, Hafslund Celsio.


“Hafslund Celsio’s project turns waste into valuable carbon dioxide removal, while providing the city of Oslo with heating and helping Norway meet its climate goals”, said Brian Marrs, senior director, Energy & Carbon Removal, Microsoft. “We appreciate Hafslund Celsio’s central role in Project Longship and are pleased to see this project develop.”
