About
Carbon to Sea Initiative is a non-profit research and development effort launched in June 2023 that has raised over $50 million from philanthropic funders to accelerate research into ocean alkalinity enhancement (OAE), and has committed more than $23 million in grants to a network of researchers. The initiative is systematically evaluating OAE as a climate solution through grant making and direct programs, and is the leading philanthropic funder of OAE research without commercial interests. It sits in the CDR ecosystem as a funder/convener rather than a supplier.
