資料簡介

未來十年，電力行業(yè)預計將在全球范圍內(nèi)投資約7.2萬億美元建設(shè)發(fā)電廠和電網(wǎng)，其中大部分投資于排放二氧化碳的煤炭和天然氣發(fā)電廠。這些資產(chǎn)通常有很長的壽命，并貢獻(未來)大量的二氧化碳排放。在這里，我們分析了發(fā)電廠排放承諾的歷史發(fā)展，并比較了現(xiàn)有和規(guī)劃中的發(fā)電廠與剩余碳預算的排放量。根據(jù)這一比較，我們得出可能數(shù)額的擱淺資產(chǎn)，將需要滿足1.5?C - 2?全球變暖的目標。我們發(fā)現(xiàn)，雖然近年來排放承諾的增長有所放緩，但目前運行的發(fā)電機仍然承諾我們的排放量(～300 GtCO2)高于1.5?C - 2?C的平均情況(～240 GtCO2)。此外，目前的發(fā)電廠管道將增加幾乎相同數(shù)量的額外承諾(～270 GtCO2)。因此，即使整個管道被取消，也需要將全球20%的產(chǎn)能擱淺，以滿足《巴黎協(xié)定》中設(shè)定的氣候目標。我們的研究結(jié)果可以幫助企業(yè)和投資者重新評估他們在化石燃料發(fā)電廠的投資，并幫助政策制定者加強他們的政策以避免進一步的碳鎖定。

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.
