Marine Carbon Dioxide Removal
Marine-based CDR techniques are gaining increased attention to achieve the necessary CO2 removal for climate stabilisation. This conference will bring together experts from diverse disciplines, including marine biology, oceanography, climate science, environmental engineering, policy, and economics, to discuss marine CDR approaches’ potential, feasibility, efficiency, risks, and the need for adequate monitoring and policy regulations.
Deliberate and active carbon dioxide removal (CDR) from the atmosphere is critical to achieve the global climate targets. The ocean plays a key role in regulating the Earth’s carbon cycle, absorbing approximately 25-30% of human-caused carbon dioxide (CO₂) emissions and storing about 50 times as much carbon as the pre-industrial atmosphere. Marine-based CDR techniques are gaining increased attention to achieve the necessary CO2 removal for climate stabilization. This conference will bring together experts from diverse disciplines, including marine biology, oceanography, climate science, environmental engineering, policy, and economics, to discuss marine CDR approaches’ potential, feasibility, efficiency, risks, and the need for adequate monitoring and policy regulations.
The primary objectives of the conference are:
- To evaluate the scientific and technical viability of various marine-based CDR methods (e.g., ocean alkalinity enhancement, ocean fertilization, seaweed and microalgae cultivation, artificial up/downwelling, direct ocean capture).
- To assess the potential environmental and socio-economic impacts of marine CDR techniques.
- To foster a dialogue between scientists, policymakers, the private sector, and NGOs to align on best practices, ethical considerations, and governance frameworks.
The conference will cover the following topics:
- Technological approaches: An in-depth look at various marine CDR technologies, and the development of reliable monitoring, reporting, verification, life cycle analysis, and field trials.
- Environmental implications: Assessment of the potential impacts and risks to marine ecosystems, including ocean acidification, biodiversity impacts, and unintended consequences.
- Socio-economic considerations: Understanding the cost-effectiveness and potential co-benefits of marine CDR, the role of the carbon markets, as well as public perception and stakeholder engagement.
- Governance and regulation: Exploration of the legal and regulatory frameworks required for responsible deployment of marine CDR, including international treaties, national legislation, and voluntary industry standards.
Expected Outcomes
- A Policy Brief report summarizing a comprehensive assessment of priority research and recommendations for national and international stakeholders on approaching marine CDR development.
