Saitama City

Message from the Mayor of Saitama City 

Hayato Shimizu

As a metropolis with a population of over 1.3 million, Saitama City has been working towards the realization of an ‘all-Saitama’ decarbonized society in cooperation with citizens and businesses.
Cooperation with national and international cities and relevant institutions is also crucial to solving global problems such as climate change.

Saitama City has been working with ICLEI to share and disseminate advanced case studies and the importance of the role of local governments with participating cities at the Saitama Sustainable City Summit in 2022 and the E-KIZUNA High-Level Talks at COP29 in 2024.

We will continue to work with ICLEI and other cities to solve problems together.
