Abstract: Abstract Will power plants emit less or more CO2 in anticipation of stronger climate policies that would strand fossil fuel reserves? Here, using a worldwide data source on individual power plants’ CO2 emissions and the value of countries’ at-risk fossil fuel assets, we show that between 2009 and 2018, plants emitted more CO2 in countries where more assets would be devalued under a 1.5 °C scenario, which we theorize is due to these countries’ regulatory leniency and plants’ vested interest in long-term fossil fuel contracts. Although the extra amount of carbon emitted each year trigged by imperiled assets is relatively small, it would exhaust a sizable portion of the electricity sector’s remaining carbon budget when added up over time. This is especially true in the U.S. and Russia where up to 16% and 12% of their budgets, respectively, could be spent within ten years due solely to the stranded asset effect.
