For most of its history carbon capture and storage (CCS) has generally been regarded as a way of overcoming a shortage of oil and gas, essentially a response to an oil crisis, like renewable energy. With countries moving towards targets of net-zero CO₂ emissions (e.g., the UK and France) and potentially towards negative greenhouse gas emissions, CCS will become increasingly essential if our climate objectives are to be achieved. In order to achieve a solution on global warming, then all countries have to participate. Money spent on CCS is much more likely to get a return in terms of influencing other countries than if spent on low-carbon technologies that are already well-known and widely deployed.
