China is taking a leading role at COP21 in Paris. The nation is set to account for 30% of global investments in renewable energies through to 2020. As Intended Nationally Determined Contributions (INDC) at COP21, China is to pledge that 20% of her energy consumption will come from non-fossil fuels by 2030.
A Brookings Institution short brief of November 2015 captures China's Ambitious Targets and Policies. How China is cleaning up and may be Seeing Daylight is described in an article in The Economist (28 November, 2015: Special Report on Climate Change).
128 INDCs have been rolling in from 150 countries, representing 88% of the world's emissions. This is building up a momentum for a more positive outcome at Paris compared with previous efforts.
China's green drive is informed by growing concerns with energy security, pollution, and the imperatives of transforming the nation's development to more sustainable, balanced and higher-quality growth. Ahead of COP21, China released a Report complied by some 550 scientists and experts, on the environment impact of Climate Change on the country.
The spoilers at COP 21 no longer include China, but a handful of fossil-fuel export-dependent countries.
