China is under great pressure to make a legally binding commitment to reduce GHGs emissions under the upcoming agreement to be reached through UNFCCC talks in 2015. China will move toward a new era in addressing climate change. Against this background, the new regime for international climate governance is undergoing profound changes, manifested in economic development, GHGs emissions, and international cooperation. In the meantime, the domestic response to climate change will get deeper and more closely linked with environmental protection and ecological governance, covering the fog and haze control, GHGs reduction in industrial sectors, and short-lived climate pollutants control. In the view that climate change adaptation and mitigation, to some extent, facilitates environmental protection, and vice versa, adequate attention and recognition should be given to co-control of GHGs and local pollutants.
