Religious attributes affecting Christians’ environmentalism have received considerable attention since the publication of Lynn White's thesis in 1967, which accused Christianity as the root cause of the ecological crisis. This study aims to assess the relationship between Christianity and environmentalism in Hong Kong, an Asian city where Christianity has been introduced for just more than two centuries. In general, Hong Kong Christians had a stronger willingness to sacrifice for the environment as compared to non‐Christians. Both stewardship worldview and Christian justice and love were identified as the main drivers for environmentalism in Christians, which can be further improved via church environmental education. Our findings provide a particular example to broaden the diversity of the Christianity‐environmentalism nexus and highlight the functional role of stewardship worldview in the Hong Kong context. However, we also call for stronger environmental education in Hong Kong's church to bridge the willingness‐behavior gap among local Christians.

Waste sorting mechanisms in residential communities play a key role in informing a sustainable and collaborative governance framework for household waste management. To investigate waste sorting practices in Changsha, one of the major cities in China, a questionnaire survey was conducted which revealed a potential collaborative link between community residents and property management companies: residents who were satisfied with management measures by their property companies had a higher willingness to participate in waste sorting and join rewarding/charging schemes (N = 437 valid responses). Semi-structured interviews, however, indicated that there was a lack of effective cooperation from planning to implementation of waste sorting mechanisms among residents, property companies and the government. Execution obstacles, the hierarchy between different stakeholders, and challenges in cooperation systems were the key factors hindering the promotion of waste sorting. This study therefore calls for a co-governance network engaging different stakeholders to establish their common interest, develop infrastructure, accrue social capital as led by motivated residents, and ultimately increase the effectiveness of household waste sorting policy at the community and individual levels.

Municipal solid waste (MSW) is a growing problem worldwide posing a variety of environmental and human health impacts. Despite recycling being one major strategy to alleviate MSW production, the effectiveness of recycling has been equivocally dependent on local policy implementation and citizen environmental behavior. To enhance recycling effectiveness in Hong Kong, the government has established Green@Community, a unified community-based network for recycling and public environmental education. Since its establishment, the number of visitors to and the amount of recyclable materials collected at the network increased steadily over time. Our study is the very first to investigate the effectiveness of this territory-wide recycling network. Through a questionnaire survey, we found that respondents’ recycling traits were stronger if they have accrued gift tokens through participating in recycling activities. Visiting a Green@Community facility could also enhance knowledge of the types of acceptable recyclables, and respondents who had visited a Green@Community facility agreed that education and publicity could increase the recycling rate in Hong Kong. These findings highlighted the effectiveness and uniqueness of this community-based recycling network, its role in raising recycling knowledge, and its implications for policymakers and urban planners of densely populated cities to leverage society’s recycling participation, but also called for more efforts on developing, promoting, and incentivizing the usage of such a network to further enhance recycling and alleviate MSW production in Hong Kong.
