According to the IPCC, to achieve net zero emissions, carbon dioxide removal (CDR) will be needed to “counter-balance hard to abate residual emissions” from sectors like agriculture, shipping, and aviation. This could occur on land or in the ocean. For example, through natural upwelling (i.e., Combining AU with AD—i.e.,
