Why We Need CCS, Part 4: Carbon Negative Solutions

As discussed in a previous post, CCS is likely to play a very important role if climate science is eventually proven correct and long-term atmospheric CO2 concentration levels of ~450 ppm are confirmed as a top global priority. The possible role of CCS retrofits to the very young fleet of fossil-fueled industry currently being built in the developing world was discussed as a medium-term possibility in the case where CO2 prices rise very rapidly in the next decade. Given the massive coal-fired push towards economic growth in the developing world and the very tight CO2 budget related to the 450 ppm scenario, however, this is unlikely to be sufficient.
