The article discusses whether capturing and storing CO2 is a good way to fight climate change. Many countries are committed to reducing CO2 emissions through methods like energy efficiency and renewable energy, as well as CO2 Capture and Storage (CCS). CCS can help reduce CO2 emissions, but there are still uncertainties about the long-term effects of storing CO2, especially in the ocean. The cost of capturing CO2 needs to become more competitive, and more research is needed on the environmental impact of long-term storage. Overall, CCS is a viable option for reducing CO2 emissions, but there are still important questions that need to be answered.
