A $70/tCO2 greenhouse gas mitigation backstop for China's industrial and electric power sectors: Insights from a comprehensive CCS cost curve

► CCS is a robust backstop climate change mitigation option in China for under $70/tCO2. ► CCS may address over 80% of China's industrial CO2 emissions for a century or more. ► Known storage resources tend to be well located to serve existing CO2 sources. ► Offshore CO2 storage reservoirs may be pivotal to deploying CCS in southern China. ► CCS presents a valuable addition to China's growing low carbon energy portfolio.
