At the Bureau of Environment, we are responsible for the environmental health of Japan's capital city, Tokyo, as well as Climate Change, Control of Air, soil and water pollution, Vehicle control, Urban energy management, Natural environment, Waste management in the area Tokyo Metropolitan Government manages.
As the capital of Japan, one of the world’s leading cities, and a densely populated center of commerce and industry,
Tokyo has implemented effective policies and established a new model for low-carbon city, based on the Tokyo Metropolitan Environmental Master Plan, launched in 2008, in collaborating with its citizens, nonprofit organizations, businesses, other local governments in Japan, and major cities around the world to implement
TMG after facing challenges of sustainable and secured energy supply has been implementing various measures to promote renewable energy, energy efficiency cogeneration system, and energy supply diversification, in aim to secure energy supply and reduce the bills.
In Tokyo—where urbanization has already advanced—about half of the entire area has been built up with commercial and residential development. As a result, the nature and greenery have shrunk markedly. In order to protect and restore nature, TMG has been making efforts toward green conservation, regulating property development, and promoting greenery in urban areas, based on the Tokyo Metropolitan Nature Conservation Ordinance and the 10-Year Project for a Green Tokyo.In addition to these efforts to maintain the quantity of greenery, and in order to respond to the loss of biodiversity causing the extinction of various species at a global scale, TMG is promoting new measures for considering green quality.
In the mid-1960s, Tokyo’s air was polluted mainly by soot and smoke from factories. Today this is no longer the case, thanks to measures against stationary sources, such as strict control of boilers and other air pollutant sources and the use of higher-quality fuel.
A problem that developed later was pollution caused by the increase in automobile traffic and exhaust gas from diesel vehicles. Therefore, in October 2003, TMG established diesel vehicle emission regulations. As a result, Tokyo’s air quality has been dramatically improved.
However, other issues remain, such as measures against photochemical oxidants and air pollution in the coastal area of the Port of Tokyo. TMG is tackling these issues in order to create the world’s cleanest urban environment. TMG is also working on initiatives including measures against airborne asbestos from the demolition of buildings to relieve the concerns of Tokyo residents.
TMG adopted the Tokyo Metropolitan Waste Management Plan, a 5-year plan from 2011 to 2015 which aims to shift toward a sound material-cycle society. Through steady implementation of the policies set forth in these various plans, TMG is contributing to the creation of a sound material-cycle society.
