Environmental policy with uncertainty is often posed as a choice of price versus quantity instruments. Quantity targets are typically preferred, but paradoxically employ architecture derived from the first-best global framework that applies imperfectly to the partial equilibrium policy setting. In practice, climate policies are incremental and multi-faceted, combining economic and regulatory approaches with limited geographic scope that do not balance global benefits and costs, but nonetheless are envisioned as a noncooperative sequence of actions enabling more efficient and comprehensive global policy. This paper recognizes and evaluates price responsive emissions allowance supply schedules emerging in existing trading programs. We use simulation modeling and laboratory experiments to explore a supply schedule in a regional market. A supply schedule usefully shares the risks and benefits with respect to emissions control costs between economic and environmental interests, preserving the role for technology and energy policies that are expected to lower costs over time.
