Tokyo Metropolitan Government:
Governor Yuriko Koike

The world now faces extremely serious environmental risks that we have never experienced before, including abnormal weather associated with global warming and problems related to heat island, air and water pollution, and resource circulation. In order to pass down this irreplaceable planet earth to the next generation, Tokyo, one of the world's largest metropolises, must actively promote environmental measures and lead environmental policies not only in Japan but also globally. I feel that Tokyo has an important role in this endeavor.

The Tokyo Metropolitan Government (TMG) implements advanced policies, including countermeasures for diesel vehicles. The urban cap & trade system introduced in 2010 greatly advances energy conservation in Tokyo. In addition, we are doing our utmost to expand hydrogen energy which attracts attention globally.

In March 2016, we developed the "Tokyo Metropolitan Environmental Basic Plan" showing policy goals and direction toward the realization of an environmentally advanced city, Tokyo. In December 2016, we established the "Execution Plan for 2020" that presents concrete policy development for TMG. Taking into consideration the Tokyo 2020 Olympic and Paralympic Games and beyond, we will further advance environmental policies and develop policies strategically.

Tokyo will share information and discuss with the cities of the world, through networks including ICLEI. I hope to work hard towards positive change for the entire planet, together with the partners across the world.

Overview of Tokyo

Population: Approx. 13.507 million (2016)
Area:2,190.90km² (2016)

Situated in the southern Kanto region and almost in the center of the Japanese archipelago, Tokyo consists of the 23 wards, the Tama area, as well as the Izu and Ogasawara Islands* in the Pacific Ocean.

The mountainous and hilly areas of Tama, including the Okutama area and Mt. Takao, as well as the Pacific islands with varied natural settings are designated as nature parks such as national parks.

*The Ogasawara Islands, located 1,000 km away from the center of Tokyo, were registered as a World Natural Heritage site in June 2011.

Environmental initiatives

Tokyo is urged to provide Asian cities, where air pollution and waste are becoming increasingly serious issues, with the experience and policy making know-how it has acquired by taking leadership in addressing these challenges. By organizing training sessions and workshops in Tokyo and various other cities, Tokyo is making the most out of the framework for international cooperation in order to offer its policymaking know-how and technology and meet the requests of these cities.

In 2010, Tokyo launched the first urban cap-and-trade system (greenhouse gas emission reduction obligation and emissions trading scheme) for large-scale businesses in Japan, and 5 years after its launch during the first planning period, all target facilities achieved its obligations to reduce a total of 14 million tons of CO2 emissions.
