Significant developments in durable carbon removal (CDR) occurred this week, with Altitude, Frontier, Microsoft, and other companies signing agreements to purchase CDR credits. Altitude, Frontier, and Microsoft purchased significant amounts of CDR credits from various providers, while partnerships were formed to advance carbon removal projects. Canadian project developer Deep Sky achieved Quebec's first permanent removal and geological injection of captured CO2, and other projects such as 44.01's CO2 mineralisation in the UAE are scaling up. Financing news and research updates in the climate solutions space were also highlighted, with CDR.fyi offering free access to market insights and company profiles related to climate solutions.
