En-ROADS adds Ocean Alkalinity Enhancement feature for climate planning

Ocean Visions has added a new Ocean Alkalinity Enhancement feature to the En-ROADS Climate Solutions Simulator, giving users a way to test how marine carbon dioxide removal could fit into climate strategies. The update is meant to help governments, investors and other stakeholders weigh costs, constraints and uncertainties as carbon removal needs grow.

Why it matters: - Marine carbon dioxide removal is getting more attention as climate targets tighten and carbon removal needs grow. - The new En-ROADS feature gives decision-makers a way to compare Ocean Alkalinity Enhancement with other climate solutions in a widely used simulator. - Ocean Visions and Climate Interactive say the tool can help users assess tradeoffs before making policy, investment or technology choices.

What happened: - Ocean Visions announced a new Ocean Alkalinity Enhancement feature inside the En-ROADS Climate Solutions Simulator on July 14, 2026. - The feature was developed with Climate Interactive and is based on climate models. - The update lets users explore how OAE could contribute to global carbon removal needed to meet climate goals. - The simulator is designed for users across sectors and does not require modeling expertise.

The details: - The new feature covers both mineral-based and electrochemical OAE approaches. - Users can explore climate outcomes from scaling OAE. - Users can examine deployment constraints, costs and uncertainties. - Users can compare OAE with other carbon dioxide removal approaches. - Users can test policy, investment and technology assumptions. - Users can visualize results instantly through interactive scenarios. - En-ROADS has been used by more than 1.5 million people worldwide. - The En-ROADS network includes more than 960 Climate Ambassadors in 91 countries. - Between 2022 and 2025, simulators from Climate Interactive and MIT Sloan informed 58 government, investment, corporate strategy, philanthropic and higher-education policies and initiatives. - Ocean Visions CEO Brad Ack said the tool will introduce millions of simulator users to Ocean Alkalinity Enhancement and help them assess how it fits within climate mitigation portfolios. - Climate Interactive Executive Director Andrew Jones said the feature reflects current scientific understanding of OAE's opportunities and limitations in a transparent and evidence-based way. - More information is available at Ocean Visions.

Between the lines: - The launch signals growing effort to move marine carbon removal from research circles into mainstream climate decision tools. - En-ROADS already has broad reach, so adding OAE could shape how nontechnical users think about ocean-based carbon removal. - The framing emphasizes uncertainty and constraints, not just potential, which may help avoid overselling the technology.

What's next: - Governments, investors and other stakeholders can now use En-ROADS to test OAE alongside other climate pathways. - The feature may influence future climate strategy discussions as users explore how carbon removal could scale. - Ocean Visions and Climate Interactive are likely to keep advancing tools that translate emerging climate science into decision support.
