Estimation of environmental costs of greenhouse gases emission in Mashhad dairy farms

The emission of greenhouse gases from different sources, especially agricultural sector is one of the main environmental pollution factors and as a resource of major changes in climatic and biodiversity. This study has been conducted through collecting cross section survey data from 85 dairy farms in Mashahd district in 2006. The stochastic frontier output distance model was estimated to derive the related environmental cost. The results showed a share of 10.68 and 67910.3 Milliard Rials environmental cost due to greenhouse gases emission in Mashhad and Iran dairy farms, respectively. These findings can make a basis for planners and policymakers to have a better knowledge of environmental costs. Finally, imposing the environmental taxes (green tax) for pollutant firms, as well as constructing an appropriate strategy to reduce their pollution via participatory management and Carbon sequestration are some policies recommended here.
