We carefully address the complex challenges of  ocean alkalinity Enhancement

The successful implementation of large-scale Ocean Alkalinity Enhancement (OAE) projects requires the development of innovative technologies capable of supplying alkalinity agents produced in an eco-responsible manner. These technologies must meet high standards of reliability and scalability.

The introduction of alkalinizing agents, such as ground limestone or olivine, into the ocean entails potential environmental risks, including the release of harmful substances and the alteration of local water quality. Vigilant monitoring and verification, as well as transparent reporting, are essential to effectively manage these risks.

One of the most significant challenges lies in establishing a robust regulatory framework for OAE projects to ensure their safe and responsible execution on a global scale. This necessitates the development and adoption of international agreements and protocols.

To understand the impact of OAE on marine ecosystems and quantify its capacity to sequester atmospheric CO₂ over the long term, OAE technology development requires a sustained and ongoing commitment to long-term monitoring and research activities.

Implementing large-scale Ocean Alkalinity Enhancement (OAE) projects requires significant investment, and their economic feasibility depends on public policies, and financial mechanisms such as carbon markets. It is therefore essential to formulate financial frameworks and public policies capable of supporting these initiatives, with particular emphasis on solutions that guarantee effective long-term carbon sequestration, with no risk of reversibility and no adverse impacts on ecosystems.

Public perception and acceptance of OAE projects are essential to their success. This requires transparency, active public engagement and educational efforts by private market players and public scientists.

OAE presents ethical dilemmas linked to human intervention in natural systems and the risk of involuntary consequences. It is therefore essential to conscientiously integrate ethical and social dimensions into any OAE implementation, promoting decision-making based on eco-responsibility and social justice.
