Environmental issues in Japan
In the period of rapid economic growth after World War II, environmental policies were downplayed by the government and industrial corporations; as a result, environmental pollution was widespread in the 1950s and 1960s. Responding to rising concern about the problem, the government introduced several environmental protection laws in 1970. The oil crisis in 1973 also encouraged the efficient use of energy because of Japan’s lack of natural resources. Current environmental issues include urban air pollution (NOx, suspended particulate matter, and toxics), waste management, water eutrophication, nature conservation, climate change, chemical management and international co-operation for conservation.
Japan is one of the world’s leaders in the development of new environment-friendly technologies, and is ranked 20th best in the world in the 2010 Environmental Performance Index. As a signatory of the Kyoto Protocol, and host of the 1997 conference which created it, Japan is under treaty obligation to reduce its carbon dioxide emissions and to take other steps to curb climate change.
