Vancouver-based Arca Climate has signed a landmark offtake agreement with Microsoft to deliver 300,000 tonnes of carbon dioxide removal (CDR) over the next decade. The deal validates Canada’s global leadership in carbon removal technology.
Arca’s industrial mineralization process transforms atmospheric CO₂ into rock by repurposing mine tailings and waste rock, creating permanent carbon storage with minimal land or water use. CEO Paul Needham called the partnership a breakthrough for scalable, durable carbon removal. Co-founder Dr. Greg Dipple noted it builds on 20 years of research and 30 mining partnerships worldwide.
