The Implementation and Implications of Sustainable Development Goals at City Scale and Sustainable Urban Development Path

Cities were products of human social development, but the environmental pollution problems brought by high-density buildings and high-density populations in cities had become increasingly serious. The 17 Sustainable Development Goals proposed by the United Nations in 2015 were closely related to urban sustainable development issues. Based on it, this article analyzed the impact of SDGs and related theories on urban sustainable development and possible development directions. Starting from the impact of SDGs on urban sustainable development, elaborated on their impact on already implemented urban sustainable projects and relevant theories. It concluded that the future development of sustainable cities should be based on existing cities, with different focuses on developed and developing countries, but both require the protection of historical value landscapes and the greening of existing facilities. By explaining the theories and practical cases related to SDGs and sustainable cities, hoping to provide a reference and guidance for the path of urban sustainable development.
