Abstract
A unique GHG emission decline target was released by the Chinese government to facilitate the decrease in GHG emission per unit of GDP in China. In other words, an increase in GHG is permitted under a GDP reflecting a better quality environment quality. Therefore, technology promotion and policy evolution are necessary to realize this within a limited period. This research considered a GHG emission tax and subsidy policy to achieve environmental targets via environment friendly vehicle introduction and clean energy promotion. An optimization simulation model based on extended input-output model was explored to compare with four policy scenarios. The simulation result shows that hybrid vehicle and electric vehicle introduction are powerless to meet environment targets unless more attention is paid to solar power and wind power along with thermal power. This research proposed an optimal GHG emission tax rate and subsidy rate for policy makers in China to reach their environment goal.

Climate change has become one of the greatest challenges of our time
The simulation result shows that hybrid vehicle and electric vehicle introduction are powerless to meet environment targets unless more attention is paid to solar power and wind power along with thermal power
In 2010, China's total greenhouse gas (GHG) emissions accounted for 26% of the total world emissions, which was far more than 17.2% (IEA 2012) of the U.S ranked in second place
Summary
How to protect the Earth’s climatic environment has become the most serious challenge faced by humans. China's GHG emission issue has become a common concern of the world's governments and academia. To deal with this situation, the Chinese government established China's GHG emission reduction target during COP15 of the UNFCCC: the GHG emissions per unit of GDP in 2020 will be reduced by 40%-45% compared to that of 2005 (CGC 2011, 2015).This research aims to propose an optimal policy to meet that environmental target through a GHG emission tax-subsidy policy introduction via hybrid vehicle (HV) and electric vehicle (EV) popularization and clean energy promotion using an optimization simulation model exploration based on an extended Input-output model(NBSC 2013)
