Shifting to natural gas has been indentified as part of the solutions for climate change mitigation. This has been the main reason why Qatar, in its submission to WTO, has proposed liberalizing natural gas and natural-gas-related technologies as a way to reduce GPIG emissions. A coal-fired power plant is more carbon-polluting than one which uses natural gas, but if coupled with carbon capture and storage (CCS) technology, it is more climate-friendly than a natural-gas-fired power plant without CCS. Besides, a country’s choice of fuels and technologies depends to a large extent on its resource endowments and their relative prices.
