AB: Non-CO2 trace gases and aerosol provide a significant fraction of current and projected climate forcing. While the emission allowance trading system embodied in the Kyoto Protocol, which recently came into force, makes provision for national crediting of reductions in emissions of long-lived trace gases (specifically methane, nitrous oxide, fluorocarbons, sulfur hexafluoride, and perfluorocarbons), emissions reductions due to precursors of ozone or black carbon aerosol are not credited. Systems for greenhouse-gas emissions trading are being adopted within and among "Kyoto" countries, including the EU, and emissions trading systems are under development for several states of the US. Successor arrangements to Kyoto for subsequent periods beyond 2012 are also under consideration. Therefore, it is important to examine whether an extended allowance trading system involving a broader suite of trace constituents can be constructed that would meet environmental, political, and economic criteria of efficacy and feasibility. In this paper, we explore the specific characteristics needed to make such a system successful including design of monitoring, modeling, and enforcement. We consider whether such a system might improve upon or dilute the benefits of a system based on long-lived constituents alone.
