The purchases were selected to support early-stage carbon removal pathways with high long-term potential, including first-of-a-kind and research-intensive projects that are not yet served by mainstream buyers. 

The portfolio includes a wide range of removal methods including biochar, BioCCS, next-generation direct air capture, enhanced rock weathering, biomass storage, and mineralization. Many of the supported projects combine durable carbon removal with co-benefits such as improved soil health, waste management, reduced air pollution, and local economic development.

Examples of companies supported through the Salesforce-backed purchases include Kairos Carbon, developing a novel BioCCS pathway using wet organic waste; Norma and Arbon, advancing next-generation DAC technologies; PyroCCS, integrating community-led biochar production with ecosystem restoration in Namibia; and Flux, deploying a new mineral feedstock for enhanced rock weathering with agroeconomic co-benefits

“Scaling carbon removal is not just about buying tonnes that exist today. It is about enabling technologies and the ecosystem that we need tomorrow,” says Robert Höglund, Head of Climate Strategy and CDR at Milkywire. “This portfolio reflects what happens when a buyer is willing to support uncertainty, learning, and first-of-a-kind deployments. That is how future supply is built.”

Salesforce’s commitment was made as part of its pledge as a founding member of the First Movers Coalition to purchase $100 million in durable carbon removal by 2030. The collaboration with Milkywire covers $5 million and was designed to channel early capital into promising but still immature technologies that struggle to attract buyers focused on near-term volume.

“To tackle climate change at the pace required, companies need to invest in solutions before they are fully proven at scale,” says Jamila Yamani, Director of Climate and Energy at Salesforce. “Through our collaboration with Milkywire, we are helping move durable carbon removal from concept toward commercial reality, while supporting approaches that deliver long-term climate impact, including the use of AI-based tools to improve monitoring, efficiency, and scalability across emerging carbon removal pathways.”

Alongside the announcement of these completed purchases, Milkywire is opening its next global call for proposals for durable carbon removal* and will make additional catalytic purchases for Salesforce in 2026. 

In total, the Salesforce-backed portfolio includes six biochar projects, three BioCCS projects, five DACCS projects, three enhanced rock weathering projects, one biomass storage project, and one mineralization project.
