Green city—future sustainable development and smart growth

The concept of the green city originally came from Europe and the North American countries, where it is very different from the concept in Asian countries because of climate, the people’s backgrounds, and the culture, goals, and history of city development. A green city is a city that demonstrates high environmental performance compared to established criteria in terms of 1) the quality of environmental assets (air, water, land / soil and biodiversity), 2) the efficient use of resources (water, energy, land and materials) and 3) mitigating risks and adapting to the risks of climate change, while maximizing economic and social co-benefits, taking into account the context of the city (population, socio-economic structure and geographic and climatic characteristics). City greening is one of the ways to pursue a green city. It is aimed at replacing the loss of green spaces that have disappeared in ongoing urban land conversion for housing and transportation. As stated in the definition of the Green City approach, measures to improve the environmental performance of a city should also seek to maximize economic and social benefits. These links between economic, social and environmental goals will provide additional motivation for city leaders to take green city action. Keywords
