We propose a new policy instrument that leverages adverse selection when Pigouvian policies are infeasible or undesirable. Our policy gives firms the option to pay a tax on their voluntarily disclosed emissions, or an output tax based on the average emissions among undisclosed firms. We derive sufficient statistics formulas to calculate the welfare gains relative to an output tax, and an algorithm to implement the policy with minimal information. In an application to methane emissions from oil and gas fields, our policy generates significant welfare gains. Finally, we extend our analysis to the design of international carbon policy.
