Abstract This paper extends the green paradox literature by providing empirical insights into its existence. To check the green paradox theory, I analyse the production of coal in four major coal-producing US states that announced a greenhouse gas action plan. To form a statement on whether there is a treatment effect caused by the green policy, I employ Synthetic Control Methods to calculate counterfactual coal production trajectories. I find that Montana experienced a high and statistically significant increase in coal production that is supported by a set of validity indicators. However, there is no evidence for a paradox in Kentucky, Pennsylvania and Virginia.

绿色悖论的综合控制评估：气候行动计划的作用

摘要本文通过对绿色悖论文献的存在进行实证研究，对绿色悖论文献进行了扩展。为了检验绿色悖论，我分析了宣布宣布温室气体行动计划的美国四个主要产煤州的煤炭生产。为了说明绿色政策是否会产生处理效果，我采用了综合控制方法来计算反事实的煤炭生产轨迹。我发现，蒙大拿州的煤炭产量在统计上显着提高，而这在一系列有效性指标的支持下得以实现。但是，没有证据表明肯塔基州，宾夕法尼亚州和弗吉尼亚州存在悖论。
