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
