Not only the resource as such which embeds the carbon component is of relevance, in fact this risk is exacerbated by changes in global climate policies in the negotiations of which many individual countries may have a very limited role. If ceteris paribus the issue of climate change is to be embraced and to be transformed into stringent carbon reduction policy in the economically leading countries and regions across the world, this would be expected to boost the role of nuclear in securing power supply. This is particularly relevant for fair comparisons involving coal- and gas-based technology with application of carbon capture and storage (CCS). Numerous publications of CCS promoters and official statistics providers present estimates (or rather projections assuming deployment of cutting-edge technology and contestably high learning rates), comprising GHG emissions at the generating plant only.
