Capturing carbon dioxide and turning it into commercial products, such as fuels or construction materials, could become a new global industry. On average each utilization pathway could use around \(0.5\) giga tonnes of carbon dioxide annually that would otherwise escape into the atmosphere. A top-end scenario could see more than \(10\) giga tonnes of carbon dioxide a year used, at a theoretical cost of under \(\$100\) per tonne of carbon dioxide. Clearly, carbon dioxide utilization can be part of the solution to combat climate change, but only if those with the power to make decisions at every level of government and finance commit to changing policies and providing market incentives across multiple sectors.
