Why is the air in Japan so good?

In 1967, Japan enacted the "Basic Law on Pollution Countermeasures", which stipulated air and water quality standards. In 1971, the National Environment Agency was established and began to use national power to comprehensively promote pollution control from the legislative level. After the first oil crisis in 1973, the pace of energy conservation and pollution control accelerated. By the new century, Japan's industrial pollution has been fully controlled. The water quality of Japan's sewers, the Seto Inland Sea and Lake Biwa, has improved significantly. The air quality in most cities is not inferior to that of most resorts in our country

What is more noteworthy is Japan's environmental protection legal system and the cultivation of citizens' environmental awareness. The Japanese government not only initiated the Kyoto Protocol for the international control of greenhouse gas emissions, but is also the most active country in promoting the circular economy model: it has promulgated the Basic Law for Promoting the Establishment of a Circular Society, the Effective Utilization of Resources Promotion Law, the Construction Seven laws, including the Recycling Law and the Container Recycling Law, have established one of the world's best three-wheel-driven garbage recycling systems: government (government), enterprise (enterprises), and citizens (people). Moreover, this concept of circular economy is not only supported by the law, but also takes root among major companies and the public. Large companies such as Toshiba and Panasonic have formulated medium- and long-term goals based on their own environmental concepts, listed a schedule for zero waste discharge and 100% resource recycling, and implemented it on specific products, while the public has begun to supervise the government and enterprises. In terms of promoting environmental protection through personal actions, Japan's environmental NGOs are among the largest in the world.

In short, Japan’s current environment can be said to be surrounded by industrial civilization with green waters, green mountains, blue skies and blue seas. Like Japan during its economic take-off, our country has also followed a path of prioritizing the development of heavy and chemical industries, and has already experienced obvious environmental deterioration: our country's existing desertified land area is more than 2.674 million square kilometers, accounting for 10% of the total land area. 27.9%, and it is still increasing by more than 10,000 square kilometers every year; 471 counties in 18 provinces in my country, the cultivated land and homes of nearly 400 million people are threatened by desertification to varying degrees; my country's current total wastewater discharge is 43.95 billion tons , exceeding 82% of the environmental capacity... These facts have shown that my country's domestic resources can no longer support the continued growth of traditional industrial civilization methods, and the environment is even less able to support the continued expansion of high-pollution, high-consumption, and low-efficiency production methods.
