| Abstract: | This paper investigates the economic implications of a comprehensive approach to sustainable greenhouse policies, that strives to stabilise the atmospheric concentration of the five major greenhouse gases at an ecologically determined threshold level. Conditions for an efficient allocation of abatement effort among pollutants and over time, are derived within a theoretical optimisation model. This model is empirically specified and adapted to a dynamic GAMS algorithm. Through the use of simulation runs for a time period of 200 years (1990–2190), the economics of greenhouse gas accumulation are explored. Long-run cost associated with the above stabilisation target, are evaluated for two different policy scenarios: a comprehensive approach that covers all major greenhouse gases simultaneously, and a `piecemeal approach' that is limited to reducing CO2 or a selected subset of greenhouse gases, respectively. By comparing simulation results, potential losses in efficiency associated with a piecemeal approach are evaluated, and policy implications are discussed. |
