To meet the Paris climate goals, CO2 will need to be removed from the atmosphere at rates of up to 10GtCO2/y. The nascent field of Carbon Dioxide Removal (CDR) encompasses nature-based, technological, or hybrid solutions. For example, utilizing and storing biomass or modifying ocean alkalinity can lead to increase in carbon sinks. Some traditional natural solutions may scale quickly, but limited by land availability and risk of reversal, i.e., a ‘durability problem’. But some methods are more reliable than others. Technology-based solutions hold promise, but are slow at scale-up to climate relevant volumes. Also needed are hybrid technology-enhanced natural solutions, involving major management interventions. This session solicits contributions on everything CDR, including 1) new scientific and technical advancement, 2) monitoring, verification, and reporting (MRV), 3) critical assessment and synthesis of CDR technologies, 4) impact of large-scale CDR deployment on the Earth system and society, and 5) policy and market implications.
