The next two decades are crucial in terms of all countries adopting green and low-carbon development and systematically transforming their energy structure to clean energy. China is the world’s biggest greenhouse gas emitter, but it also leads in energy conservation and new energy usage. China has been actively responding to the challenges of climate change and has encouraged green and low-carbon development. China’s document to the United Nations Framework Convention on Climate Change, Enhanced Actions on Climate Change: China’s Intended Nationally Determined Contributions (INDC) outlined its pledge to peak carbon dioxide emissions before 2030, and to raise the proportion of non-fossil fuel energy to 20%. China also reached a series of bilateral agreements with the US, the EU, India, UK and France on climate change. China has also been promoting South-South cooperation to address climate change. China is now viewed as the key driver of the Paris Agreement.
