Ocean Visions Adds Marine Carbon Removal Tool to Climate Simulator

Ocean Visions has launched an Ocean Alkalinity Enhancement feature within the En-ROADS Climate Solutions Simulator, developed by Climate Interactive and MIT Sloan. The addition allows users of the science-based platform to explore how the marine carbon dioxide removal pathway could contribute to global carbon removal goals while examining its constraints, costs and uncertainties. Built in partnership with Climate Interactive, the feature brings one of the most actively researched marine removal approaches into a decision-support tool already used by more than 1.5 million people worldwide.

 

The New Simulator Feature

 

Ocean Visions has introduced a dedicated tool for a specific carbon removal pathway. The Ocean Alkalinity Enhancement feature sits within the En-ROADS Climate Solutions Simulator. That simulator was created by Climate Interactive and MIT Sloan as a science-based platform. The new feature was developed in partnership with Climate Interactive. It draws on Ocean Visions and its network of subject experts.

The feature is grounded in established climate modelling. It allows users to explore how the approach could contribute to global carbon removal needs. Users can also examine the constraints, costs and uncertainties involved. This balanced framing presents both the potential and the limitations of the pathway. The result is a tool designed to support realistic assessment rather than optimistic projection.

 

Addressing a Knowledge Gap

 

The addition responds to a growing need among decision-makers. Knowledge of marine carbon dioxide removal continues to expand across the research community. This creates an increasing need to help decision-makers understand how various approaches fit together. Individual pathways must be understood within the context of overall climate strategies. The feature aims to bridge that gap between research and strategic planning.

Ocean Alkalinity Enhancement represents one of the most actively researched approaches. The feature brings this pathway to a widely used decision-support tool for climate strategy. This allows users to test scenarios and compare outcomes across options. It also enables them to explore the tradeoffs between different approaches. Situating the pathway alongside alternatives supports more informed strategic choices.

Accessibility and Reach

 

The simulator is designed for a broad audience rather than specialists. Unlike highly specialised technical models, En-ROADS engages diverse users across sectors. It does not require modelling expertise to operate effectively. This accessibility broadens the range of people who can explore climate scenarios. It brings complex modelling within reach of non-technical decision-makers.

The platform's reach is substantial across the global climate community. En-ROADS has been used by more than 1.5 million people worldwide. It is supported by a network of more than 960 Climate Ambassadors across 91 countries. This infrastructure extends the tool's influence well beyond individual users. The scale of adoption gives the new feature significant potential exposure.

 

Capabilities of the Tool

 

The feature covers multiple variants of the alkalinity enhancement approach. It represents both mineral-based and electrochemical methods within the simulator. This breadth reflects the diversity of techniques under active research. Including both allows users to compare distinct routes to the same outcome. It provides a more complete picture of the pathway's potential.

The tool offers several specific analytical functions. Users can explore potential climate outcomes associated with scaling the approach. They can examine deployment constraints, costs and uncertainties in detail. The feature also allows comparison with other carbon dioxide removal approaches. Users can test policy, investment and technology assumptions and visualise results instantly through interactive scenarios.

 

Influence on Policy and Strategy

 

The simulator has demonstrated real-world influence on decision-making. Between 2022 and 2025, simulators from Climate Interactive and MIT Sloan informed 58 policies and initiatives. These spanned government, investment, corporate strategy, philanthropic and higher-education settings. This track record indicates the tools reach beyond academic exercise. It suggests the new feature could similarly shape practical climate decisions.

The addition positions marine carbon removal within mainstream climate planning. By integrating the pathway into a widely used tool, it becomes part of standard scenario analysis. This helps decision-makers weigh ocean-based approaches against terrestrial alternatives. The emphasis on constraints and uncertainties encourages realistic assessment of the pathway. This approach supports more grounded discussion of the role marine carbon removal might play.
