Oil and gas industry in the United Kingdom model actually exists. It is proposed to do CCS by combining three distinct processes: capturing the carbon dioxide at a power station or other major industrial plant, transporting it by pipeline or by tanker, and then storing it in geological formations. Some of the best natural repositories are depleted oil and gas fields, such as those in the North Sea. The oil and gas industry's knowledge of undersea geology, reservoir management and pipeline transport will play an important role in making this technology work effectively.

Environmental impact of hydraulic fracturing life cycle of oil or coal. Until recently, Canadian provinces such as Alberta, Saskatchewan, and Nova Scotia produced over half of their electricity from coal combustion whereas Ontario has already completely phased out coal-powered electricity. Switching from coal- to natural gas-powered electricity can reduce carbon dioxide emissions by ~50% and also decrease the amount of NOx and SOx emitted to atmosphere. Lack of baseline data or before-and-after hydraulic fracturing sample collection and analysis makes it challenging to quantify environmental impacts (if any) resulting from hydraulic fracturing. Hydraulic fracturing fluids include proppants and other substances, which may include toxic chemicals. In
