Tradable Permits for Environmental Protection: Case Study of an Integrated Steel Plant in India

Abstract

Cost effective policies allow minimising the compliance costs associated to reaching a desired environmental quality target. In this paper a conceptual model has been developed to examine the compliance costs under an intra-plant emission trading system for a non-uniformly mixed assimilative pollutant. The model incorporates the number of emission sources, the concentration of pollutants emitted at each source, the marginal cost of abatement for each source, the transfer coefficient that relates emission at each source with the impact on ambient air quality, and the desired ambient air quality target. The model is applied to an integrated steel plant in India. Results of this study demonstrate that the emission trading is more cost effective than the existing regulatory system. Further, intra-plant trades would result in significant savings to the steel plant while securing an improvement in ambient air quality in the studied geographical area.tradable permits, carbon trading, pollution abatement, emission, intra-plant trades, ambient air quality, integrated steel plant, India, Economics, Environment Studies,
