¹⁸² Most likely the strategy on power generation annexed to China's Five-Year Plans. China's energy sector contributed an estimated 9.5 GtCO₂eq, representing close to a fifth of a total of 48.9 GtCO₂eq global GHG emissions (including land-use change and forestry) in 2014. See World Resource Institute, ‘CAIT Climate Data Explorer’ (2018) <https://www.wri.org/resources/data-sets/cait-country-greenhouse-gas-emissions-data>. China's National Development and Reform Commission (NDRC) conducts some consultations with stakeholders during the drafting of the five-year plan, though no complete EA process.
