Thus, assessing severe weather risk is crucial for evaluating urban sustainability; understanding trends, causes, and impacts on socioeconomic development; and supporting the United Nations Sustainable Development Goal (SDG) 13. Using meteorological data from 1980 to 2020, we investigate five disaster-causing severe weather events in China and construct a comprehensive index of extreme climate risk (CIECR) at the county, city, province, and national levels. The CIECR can identify high-risk regions and primary severe weather events and provide early warnings. We empirically test the impact of extreme climate risks on agricultural production, industrial structure, and labor employment. The results show high risks in Xinjiang, northern Inner Mongolia, and southern regions, with high temperatures, low temperatures, and high winds as the leading risks. At the national level, the extreme climate risk fluctuates, indicating climate warming. While risks reduce agricultural production and employment, they promote modern agriculture, industrial production, and urbanization. The novelty of the study lies in its development of the county-level CIECR, which can capture heterogeneity characteristics and provide microdata support for urban climate change research and efforts toward SDG 13.

The findings were also compared with situations in other informal settlements in Brazil, Bangladesh, and Nairobi. The results indicated the inadequacy of communal septic tanks in informal settlements due to factors such as substandard system design, limited support and communication between authorities and residents, and the gap between septic tank availability and capacity vis-a-vis demand. Other limiting factors included limited land availability and irregular geomorphology, the latter of which affected the siting and operation of septic tanks due a lack of room for upgrades or expansion in response to continuous population growth.

To accelerate the green economy transition, Chenzhou should improve the market-oriented allocation system for resources and environmental factors, explore the “gross ecosystem product + eco-environment-oriented development” project implementation model, encourage enterprises to adopt environmental, social, and governance principles, and foster synergies between supply and demand.

How enterprises can reasonably and effectively improve their ESG performance and promote their green and sustainable development has become a major practical problem that urgently needs to be solved. Based on social learning and dynamic competition theories, this study takes Shanghai-Shenzhen A-share listed companies from 2011 to 2021 as research samples, empirically tests whether there is a peer effect in the ESG performance of listed companies in China, and examines the generation mechanism and influencing factors of the peer effect in the ESG performance of enterprises.
