A global climate solutions simulator has expanded its toolkit to include marine carbon dioxide removal (mCDR), giving policymakers and researchers a new way to model ocean-based carbon sequestration. The update allows users to compare mCDR methods like ocean alkalinity enhancement and artificial upwelling alongside traditional land-based approaches. The simulator helps stakeholders assess the potential costs, scalability, and environmental trade-offs of different carbon removal strategies. By adding mCDR, the platform aims to fill a gap in climate modeling that often overlooks ocean-based solutions, which could play a significant role in meeting net-zero targets. For carbon market participants, the inclusion of mCDR in a widely used simulator could influence how ocean-based credits are valued and verified. The tool provides a more complete picture of the mitigation landscape, though real-world deployment and monitoring remain challenges.
