Abstract If we were in a global war against cli- mate change, we would carry out large- scale carbon capture, utilization, and storage (CCUS) (Smit et al., 2014). Some argue that if we fight the war against climate change via CCUS, this implies that we are promoting the continued use of fossil fuels instead of replacing fossil fuels by renewable energy such as solar and wind. At present, the contribution of fos- sil fuels in our energy supply is over 80%, while the renewable is only 10% (Interna- tional Energy Agency (IEA), 2013). Most, if not all, of the energy scenarios predict an increase in the share of the renewables, but in absolute numbers the fossil fuels will continue to provide most of our energy needs in the foreseeable future. This is simply because the growth in renew- able energy will not be able to keep up with our increasing energy demand associated with a growing world population. In such a scenario, a war against climate change without CCUS implies that we have to dramatically reduce our current energy consumption, and hence, accept a dramatic reduction in GDP. Thus, the adaptation of large-scale CCUS might be inevitable to mitigate ever-increasing CO2 emissions with given population growth predictions.
