Carbon capture technology could be one of the many tools used to combat global warming. By using technology to capture carbon before it escapes, it will help reduce greenhouse gas emmisions. It could also make carbon based fuel productions healthier for the environment, for example by capturing the carbon released when extracting natural gas.
Carbon Capture and Storage (CCS) technology is not ready to be developed and may never be. That is not to say it should not continue to be investigated, as should all solutions, but CSS as currently proposed is little more than the latest twist on the old philosophy of stashing our environmental waste somewhere that we hope it will not cause a problem in our life time.
