The 2030 Agenda for Sustainable Development, which has the Sustainable Development Goals (SDGs) at its core, was adopted at the General Assembly of the United Nations in 2015. Pledging that “no one will be left behind,” the Agenda is committed to achieving sustainable development in its three dimensions—economic, social and environmental—in a balanced and integrated manner. This makes it even more crucial for cities to serve a concrete and active role.

We, the cities of the world, have been undertaking ambitious efforts to address the challenges of waste management, material cycling and air pollution, which have serious impacts on citizen health and quality of life.

Moreover, in order to serve our roles as the world’s major cities, at the Tokyo Forum for Clean City & Clear Sky, which was held in Tokyo on May 22 and 23, 2018, we shared our policies and knowledge, discussed solutions, and agreed to make it our goal to realize a sustainable urban environment.

At the forum we shared the following vision to pursue.

Our Vision

  • Achieving clean cities where the concept of “mottainai” (too precious to waste) is expanding, sustainable consumption and production are making advances, and proper waste management of reduction, recycling and detoxification is secured.
  • Achieving pleasant clear skies with reduced health risks through significant reduction of the concentration of air pollutants.

With the goal of realizing this vision, we, the leaders and representatives of the world’s major cities, have agreed to commit to the following.

Initiatives to realize the vision

  • Positioning waste management measures and material cycling, along with improvement of the air environment as priority challenges to address, we will study and implement world-leading policies while also considering matters such as the economic, social, and geographic characteristics of each respective city.
  • To improve resource efficiency, we will advance measures such as reducing food waste. To improve waste management, we will adhere to the principles of reduction, recycling and detoxification, advance the building of a better recycling system and spread awareness of waste management among the citizens. In addition, in order to reduce air pollutants, we will adopt effective measures such as actively promoting the diffusion of zero-emission vehicles and other next generation vehicles, and advancing measures against PM2.5 and oxidants.
  • For the implementation of measures, we will aim to create a social movement through comprehensive advancement of various activities, including raising enthusiasm among the citizens, cooperating with private companies that have excellent technologies, and building effective system & policies.
  • We will strive to share our cities’ best practices, and maintain and strengthen our close global partnerships.
  • We will cooperate actively with international organizations and institutions such as the C40 Cities Climate Leadership Group, ICLEI-Local Governments for Sustainability, Japan International Cooperation Agency (JICA), and the World Bank, and contribute to advancing waste management measures, promoting a material-cycle society, and improving the air environment of the world’s cities.
