英文摘要	Natural gas is seen as a key interim fuel along the pathway to a zero-carbon energy system, yet there is some concern it may delay the transition. This Analysis estimates the life cycle emissions from gas-fired electricity and the abatement potential of different mitigation options. Over 100 countries pledged to reduce methane emissions by 30% by 2030 at COP26, but whether gas can serve as a bridge to lower-carbon options remains disputed. With an increasingly global supply chain, countries have different responsibilities in mitigation. We determine the global average of life cycle greenhouse gas emissions from the delivery of gas-fired electricity to be 645 gCO(2)e kWh(-1) (334-1,389 gCO(2)e kWh(-1)), amounting to 3.6 GtCO(2)e yr(-1) in 2017 (10% of energy-related emissions). Deploying mitigation options can reduce global emissions from gas-fired power by 71% with carbon capture and storage, methane abatement, and efficiency upgrades contributing 43%, 12% and 5%, respectively. Mitigation falls within national responsibilities, except an annual 20.5 MtCO(2)e of ocean transport emissions. For gas to truly be a bridge fuel, countries involved with the life cycle of gas-fired power need to deploy all mitigation options while balancing the risk of locking in carbon-intensive electricity.
