【 摘 要 】

In the Paris Agreement, many nations set ambitious global goals to stabilize and reduce carbon emissions to mitigate climate change. A large share of these emissions is caused by electricity production. Scientists have been debating the viability of using natural gas as a transition fuel while renewable energies mature technologically and economically. Although natural gas might help the energy transition by reducing emissions compared to coal, there are other long-term implications of investing in natural gas which can work against reaching climate goals. One concern is that investments in natural gas might crowd out investments in renewable alternatives. This research reviews the literature on the role of natural gas in reducing carbon emissions to mitigate climate change and to bridge between coal and renewable technologies. We advance the debate by laying out how various positive and negative effects of natural gas interrelate. Our research warns that natural gas' negative delayed and global effects can easily outweigh the positive immediate and local effects unless precautions are taken. Existing studies agree that natural gas helps avoid greenhouse gas emissions in the short term, while unintended long term effects might also hinder the transition into renewables. Our review helps to inform the policy making process by reviewing the systemic effects of using natural gas as a transition fuel and suggests policy actions to avoid the negative long term consequences.
