资料简介

未来十年,电力行业预计将在全球范围内投资约7.2万亿美元建设发电厂和电网,其中大部分投资于排放二氧化碳的煤炭和天然气发电厂。这些资产通常有很长的寿命,并贡献(未来)大量的二氧化碳排放。在这里,我们分析了发电厂排放承诺的历史发展,并比较了现有和规划中的发电厂与剩余碳预算的排放量。根据这一比较,我们得出可能数额的搁浅资产,将需要满足1.5◦C - 2◦全球变暖的目标。我们发现,虽然近年来排放承诺的增长有所放缓,但目前运行的发电机仍然承诺我们的排放量(∼300 GtCO2)高于1.5◦C - 2◦C的平均情况(∼240 GtCO2)。此外,目前的发电厂管道将增加几乎相同数量的额外承诺(∼270 GtCO2)。因此,即使整个管道被取消,也需要将全球20%的产能搁浅,以满足《巴黎协定》中设定的气候目标。我们的研究结果可以帮助企业和投资者重新评估他们在化石燃料发电厂的投资,并帮助政策制定者加强他们的政策以避免进一步的碳锁定。

Over the coming decade, the power sector is expected to invest ∼7.2 trillion USD in power plants and grids globally, much of it into CO2-emitting coal and gas plants. These assets typically have long lifetimes and commit large amounts of (future) CO2 emissions. Here, we analyze the historic development of emission commitments from power plants and compare the emissions committed by current and planned plants with remaining carbon budgets. Based on this comparison we derive the likely amount of stranded assets that would be required to meet the 1.5 ◦C–2 ◦C global warming goal. We find that even though the growth of emission commitments has slowed down in recent years, currently operating generators still commit us to emissions (∼300 GtCO2) above the levels compatible with the average 1.5 ◦C–2 ◦C scenario (∼240 GtCO2). Furthermore, the current pipeline of power plants would add almost the same amount of additional commitments (∼270 GtCO2). Even if the entire pipeline was cancelled, therefore, ∼20% of global capacity would need to be stranded to meet the climate goals set out in the Paris Agreement. Our results can help companies and investors re-assess their investments in fossil-fuel power plants, and policymakers strengthen their policies to avoid further carbon lock-in.
