Editorial introduction: Green City Challenge and Strategies

The Green City concept is a concept usually associated with the safety of the environment and puts the environment as an essential aspect in achieving sustainable development. The concept is delivered through different layers of planning and design, covering the micro, meso and macro scales of the city (Shen & Fitriaty, 2018).
