drought in the southwest of China, which were the worst since records began to be kept in the late nineteenth century, to floods and typhoons in central and southeastern China. The weather events in China in 2006 were seen to be a prelude to weather patterns likely to become more common due to global warming. Topics discussed by representatives of Asian countries and developed countries, international organisations and nongovernmental organisations, included vulnerability assessments, implementing adaptation actions in various sectors of the economy and in specific geographical areas, such as coastal and mountainous regions. Based on a recently completed survey in 2007, the Standardization Administration of China plans to further develop and improve standards for conservation and comprehensive use of natural resources in the following areas: energy, water, wood and land conservation, development of renewable energy, the comprehensive utilisation of mineral resources, recovery, recycling and reuse of scrap materials and clean production. Energy production and consumption In 2020, 84.33% of Chinese primary energy consumption relied on fossil fuels, and 56.56% of it relied on coal, down from 70% in 2011. These energy production processes generated approximately 9.9 billion tonnes of CO2, up from 8.1 billion tonnes in 2010 and accounting for 30.9% of global emissions. In 2021, China produced 7.727% of its energy from hydroelectric, 2.32% from nuclear, and 7.141% from other renewable energy sources, from 2.25%, 8.468%, 5.77%, relatively, in 2020. Chinese energy experts estimate that by 2050 the share of electricity from coal will decline to 30%–50%, and that the remaining 50%–70% will come from a combination of oil, natural gas, and renewable energy sources, including hydropower, nuclear power, biomass, solar energy, wind energy, and other renewable energy sources. In 2018, transportation's share of energy consumption in China was 10.0%, consuming 436.2 million tons carbon equivalent, up by 7.6% in 2009 and 58.6 Mtce in 1995. The growth rate of the percentage, meanwhile, have seen a steady decline from 2010 to 2018, down from 10.8% to 3.5%. According to a study by the Energy Research Institute of the National Development and Reform Commission on the economic circumstances of China's crude oil and chemical industry as of 2007, China has wasted an average of 400 million tons carbon equivalents annually. In 2020, China consumed 4.98 gigatons coal equivalents, up from 2.46 in 2006. According to Dai Yande, the chairman of the Energy Research Institute of the NDRC, while continued high
