1. Rapid economic development, with energy consumption increasing year by year
In 1978, the national energy consumption was 570 million tons of standard coal. In 2017, it was about 4.49 billion tons of standard coal, nearly a sevenfold increase, ranking first in the world for eight consecutive years. In 2018, total energy consumption was 4.62 billion tons of standard coal, a 2.9% increase over 2017. Non-fossil energy accounted for 14.3%. Preliminary statistics show that total energy consumption in 2019 was 4.86 billion tons of standard coal, an increase of about 3.3% over the previous year. 2. Air pollution, with industrial production having a significant impact Energy consumption: Industrial energy use accounts for about 70% of total social energy consumption, with steel, non-ferrous metals, building materials, and chemicals—the four major high-energy industries—accounting for 50% of industrial energy use. There are still issues of energy waste in China's current energy consumption. Areas lagging in air pollution rankings are concentrated in the Two Rivers and Two Mountains regions. Air quality rankings of 169 key cities from January to December 2018: Air quality rankings of 168 key cities from January to December 2019: Air quality status on October 21, 2019:

1. Establish a Beautiful China Green mountains always remain, clear waters flow long, and the air is always fresh. The report of the 19th National Congress of the Communist Party of China proposed accelerating the reform of the ecological civilization system and building a Beautiful China. By promoting green development, focusing on solving prominent environmental problems, strengthening ecosystem protection, reforming the ecological environment supervision system, integrating ecological civilization construction into all aspects and the whole process of economic and social development, and addressing the harmonious coexistence of humans and nature, the beautiful picture of ecological civilization construction with green mountains, clear waters, and picturesque landscapes will further unfold across the country. The Fourth Plenary Session of the 19th Central Committee of the Communist Party of China proposed adhering to and improving the ecological civilization system to promote harmonious coexistence between humans and nature. Ecological civilization construction is a millennium plan related to the sustainable development of the Chinese nation. We must practice the concept that lucid waters and lush mountains are invaluable assets, adhere to the basic national policy of resource conservation and environmental protection, follow the principles of prioritizing conservation, protection, and natural restoration, firmly follow the path of civilized development featuring production growth, affluent life, and good ecology, and build a Beautiful China. We must implement the strictest ecological environment protection system, fully establish a resource-efficient utilization system, improve ecological protection and restoration systems, and strictly enforce ecological environment protection responsibility systems. 2.
