IATA – Carbon Dioxide Removal (CDR) Technologies, Apr 2025

The main topic of the report is carbon dioxide removal (CDR) technologies and their role in achieving net-zero CO2 emissions in the air transport sector by 2050.

The report examines the most common CDR technologies, their relative cost, technological readiness, as well as associated benefits and risks. Key findings include the necessity of using market measures, such as CDR, to offset remaining CO2 emissions, as in-sector solutions like sustainable aviation fuel (SAF) will not fully cover all CO2 emissions. CDR technologies are divided into traditional and novel, based on their commercial readiness. Important aspects include techno-economic considerations such as technology readiness level (TRL) and cost, as well as additional benefits and risks.
