This study addresses the case of Tianjin in China and seeks a suitable environmental policy for the region. The Tianjin inter-regional input-output table is estimated and the economic and environmental impacts of environmental conservation technologies are measured. This study investigates the introduction of heat supply system and desulfurization technology from the perspective of effective coal use and assesses CO2, SO2 and value added repercussions of the technologies. The simulation results indicate that the biomass use in heat supply and household sectors and the introduction of simple flue gas desulfurization equipments in medium and small scale plants of industrial sectors should be simultaneously promoted to control CO2 emissions and to reduce SO2 emissions significantly. The introduction cost of the technologies accounts for approximately 2% of Tianjin's total value added in 2007, while SO2 emissions could be reduced approximately 71% compared to their 2007 levels.
