OCEAN CARBON DIOXIDE REMOVAL
Carbon dioxide removal (CDR) is becoming increasingly understood as imperative for slowing dangerous climate change. The world needs to extract and permanently sequester 100s to 1000s of gigatons of carbon dioxide over the coming decades to avoid the worst effects of climate disruption. The scale of the efforts needed comes with significant technological, political, economic, and social challenges.
To date, most of the thinking and development of CDR approaches and technologies, while relatively nascent, have been terrestrially focused. However, the Ocean holds enormous potential for CDR solutions at the needed scale given their sheer size and biological function.
Ocean CDR remains poorly understood and under-invested. There are an emerging number of scientific efforts to evaluate different ocean CDR pathways, their technical feasibility, costs and environmental implications, and there are a growing number of early stage inventors and practitioners who are pushing the technical envelopes of ocean CDR technologies. But there is no supportive policy framework for field testing and commercial scaling; awareness of the potential contributions of ocean CDR is nascent; social and political license for ocean-based approaches is uncertain; and philanthropic and private sector engagement remains small.
To address and overcome some of the roadblocks to accelerating development of ocean-based CDR, Ocean Visions will convene relevant experts and interested parties in development of road maps to identify the needed steps to accelerate development and deployment of the most viable ocean CDR approaches.
