# The Montreal Protocol converted international CFC regulation from prisoner's dilemma to coordination game through trade sanctions that made non-participation economically costly

Barrett's game-theoretic analysis demonstrates that the Montreal Protocol succeeded where most environmental treaties fail through a specific structural mechanism: trade sanctions that transformed the underlying game from prisoner's dilemma to coordination game. Before trade sanctions, each country had individual incentive to continue CFC production regardless of others' choices—classic PD where defection dominated. The protocol restricted parties from trading CFC-controlled substances with non-signatories and allowed bans on imports of products containing these substances. Once critical mass of signatories was reached, trade costs of non-participation exceeded compliance costs, flipping the dominant strategy. The minimum participation clause (two-thirds of global CFC consumption) solved the early mover disadvantage problem. The Multilateral Fund (1990 London Amendments) paid developing countries' incremental phase-out costs, eliminating their defection incentive. Barrett explicitly contrasts this with the Paris Agreement, which lacks enforcement mechanisms and thus maintains PD structure where free-riding remains individually rational. The historical record confirms: only agreements with trade sanctions, minimum participation thresholds, or side-payments to key defectors achieve durable cooperation in genuine PD games.
