Global climate change as well as energy scarcity is the most important and urgent problems facing us today. Without the effective action to reduce greenhouse gas emissions, the impacts of a changing climate will have major adverse effects on our society, the environment and the economy. Furthermore, these impacts will impair future generations. Only by establishing a low-carbon economic development model in a "low-carbon home", would the greenhouse gas emissions be cut effectively. The core of low-carbon policy is the improvement of energy utilization and the transformation of the energy structure which would enable more clean energy to be used more effectively and greenhouse gas emissions to be cut as much as possible. On the other hand, in the wake of the global financial crisis and economic slowdown, it is important to stimulate growth and promote green industries by formulating and implementing the sustainable energy policies. In this article, we present the low-carbon policy resolved by the government to push forward industrial upgrading and integration, and also discuss the development of sustainable energy.
