Yokohama Smart City Project (YSCP)

Climate Change Policy Headquarters地球温暖化対策事業本部

YSCP Vision and ObjectivesAs one of the largest cities in Japan, Yokohama aims to build the ”Next Generation Energy Infrastructure and Social System” that maximizes CO2 reduction in the forefront of innovation. The know‐how will be leveraged to deploy abroad as a city‐scale infrastructure package.

Background YSCP Vision and Objectives

Ambitious CO2 reduction target (30% by 2025)Export overseas as a city scale infrastructure package

Increasing need for energy security
