Abstract
- As the world's largest carbon emitter, China faces serious air pollution problems. Given that both carbon dioxide and air pollutants mainly come from burning of fossil fuels, the coal-to-gas policy has received widespread attention as a way to steer the public towards cleaner energy. However, inflexibility in the early implementation of the coal-to-gas policy caused a shortage of natural gas, and thus had negatively influenced households' lives. Considering the importance of clarifying the economic and environmental impacts of the coal-to-gas policy, this paper employs a dynamic recursive computable general equilibrium (CGE) model and sets different substitution scenarios, to simulate the impacts of the coal-to-gas policy on gross domestic product (GDP), sectoral output, trade, carbon emission reduction, and air quality improvement. The simulation results show that the long-term damage to GDP will be weaker than the short-term one, and carbon emissions would be reduced by 280 and 300 million tons in 2030 under the high and full substitution scenarios, respectively. The emissions of air pollutants (SO 2 and NO x) would also decrease significantly. Moreover, our results indicate that it is feasible to increase the substitution ratio in a stepwise manner and eventually achieve full substitution, which can not only effectively avoid shortages of natural gas, but also promote the coordinated control of carbon dioxide and air pollution emissions. • Coal-to-gas policy is a more effective way to reduce CO 2 emissions than SO 2 and NO x emissions. • The full alternative scenario with a step-by-step substitution approach should be adopted. • Coal-to-gas policy will reduce GDP, and the long-term impact is weaker than the short-term impact. • Some subsidies or tax incentives could be given to exports of resource-intensive goods.
