Environmental Policy and Sustainability Jeffrey Chow, Tianle Liu, Coco Dijia Du, Rui Hu, and Xun Wu. “From research to policy recommendations: A scientometric case study of air quality management in the Greater Bay Area, China.” Environmental Science and Policy 165 (2025): 104025. Focus of Study This study uses scientometric meta-analysis to examine how institutional factors shape the role of scientific research in air quality policymaking in China’s Greater Bay Area (GBA), a region with distinct “One Country, Two Systems” governance (mainland China and Hong Kong). It analyzes 687 Chinese and English-language peer-reviewed articles (2000–2019) to explore funding sources, government co-authorship, and policy recommendations. The research finds that Chinese-language articles (focused on the broader GBA) have greater government involvement in funding and authorship, and tend to offer more cautious policy recommendations. In contrast, English-language articles (focused on Hong Kong) are less likely to involve government co-authors, more likely to propose new policies, but less critical of existing policies if funded by mainland or overseas governments. Policy Recommendations Policymakers should foster a balanced science-policy interface in the GBA by encouraging more transparent collaboration between researchers and government, while preserving academic independence to ensure diverse policy insights. Additionally, establishing formal mechanisms to evaluate post-implementation policy impacts (e.g., for air pollution regulations) and promoting data accessibility across the region can enhance the translation of scientific research into effective, evidence-based air quality management. SCHOLARLY SHOWCASE Yatang Lin, Ziyang Chen, Ting Chen, Jin Wang. “ The environmental cost of power outages: Evidence from Delhi.” Journal of Public Economics (2025). Focus of Study This study explores the environmental cost of power outages in Delhi, using high-frequency outage and air pollution data. It nds that outages increase hourly NO2, NO, and PM10 concentrations by 0.4%, 1.3%, and 0.4% respectively, due to widespread use of polluting backup diesel generators. The research employs spatial DID and event-study methods to con rm causality, noting the environmental cost of outages exceeds private costs. It also evaluates Delhi’s outage penalty policy, showing signi cant welfare gains when environmental bene ts are included. Policy Recommendations Policymakers should prioritize grid modernization and generation capacity investments to reduce outages. They should also promote clean backup energy (e.g., solar-battery systems) via subsidies, tighten diesel generator emissions regulations, and incorporate environmental costs into outage-related policy evaluations to enhance air quality and public welfare. 15
