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.
