Sustainability consists of economic, environmental, and societal aspects. Concomitant with China’s rapid growth, the evaluation of China’s ability for sustainable development (SD) has become a topic of interest. Unlike previous studies that are based on provincial regions and focus on economic and/or environmental evaluations, we have evaluated the comprehensive SD ability of 34 major cities in...

The paper proposes a global mechanism to finance and promote sustainable development (SD) that is multinational, provides incentives for rich and poor countries to promote SD, incorporates the principle of common but differentiated responsibilities and links incentives and funding for SD to structural benchmarks and performance targets.
