China's sustainable development index has shown steady improvement for seven consecutive years since the assessment began, with a cumulative increase of 46.8 percent, according to a recent report released during the just-concluded COP29 climate conference.

The index was co-released by the China Center for International Economic Exchanges and the Earth Institute of Columbia University.

The index evaluates five key areas: economic development, social well-being, resource and environmental management, consumption and emissions, and governance and protection. All five sub-indices under China's sustainable development index have demonstrated upward trends, indicating progress across multiple dimensions of sustainability.

The findings suggest that China is progressively establishing a pattern that effectively supports the green, low-carbon transition and high-quality development of its economy and society, said the CCIEE.

Cities, including Zhuhai, Qingdao, Hangzhou, Guangzhou, Beijing, Shanghai and others exhibit better performance in sustainable development, according to the CCIEE.
