Summary: Nighttime light (NTL) remote sensing data have been extensively used to understand urbanization. A literature review of 688 papers published between 1992 and 2022 identified the trends and challenges in NTL-based urban applications. Future research directions include understanding scale effects and variations in NTL data, integrating multi-source NTL data with other geospatial data, focusing on the Global South, and developing new urban applications with new NTL data products. Addressing research gaps in these areas will provide new insights into urbanization under different settings.

Summary: This study investigated the impact of COVID-19 lockdowns on satellite aerosol optical depth (AOD), finding that AOD decreased in cities with reductions in NO2 emissions from the transportation sector, and increased in Taiwan where economic stimulus was used as a strategy. The analysis suggests that targeted reductions in NOx and volatile organic compound emissions from the transportation sector can improve AOD, and transitioning vehicles to electricity can achieve substantial improvements.

Summary: Remotely sensed land surface temperature (LST) is widely used in urban climate research, but it is subject to considerable angular variation due to non-isothermal facades and sensor viewing angles. This study modified and validated a satellite-based approach to estimate thermal anisotropy and compared the seasonal and diurnal variations in 25 global cities. The results show that urban thermal anisotropy is influenced by sensor angles, solar angles, urban surface properties, and geographic location. The findings provide insights for addressing anisotropy in satellite products and understanding its impact on LST applications in cities.

Summary: Since a majority of CO2 emissions from fossil fuels come from cities, it is important to use novel techniques to utilize satellite observations of CO2 and proxy species to control urban CO2. This study aims to establish the relationship between satellite observations of CO2 and the proxy species of NO2 and estimate CO2 emissions based on NO2 data. The method was tested in Buenos Aires, Melbourne, and Mexico City and proved to be viable throughout the year. This method provides a valuable observational constraint on urban CO2 emissions, with comparable monthly urban CO2 emissions estimates to inventory estimates.

Summary: This study investigated the day-to-day variations of Surface Urban Heat Island (SUHI) intensity (SUHII) in over 10,000 cities worldwide, and found that meteorological variables related to thermal admittance have a larger regulation on SUHII variations than those related to air conditions. The study also found that the impact of meteorological factors on SUHII variations differs greatly by background climates, with specific humidity having a significant control in arid zones and wind speed being weakened prominently in equatorial zones. Furthermore, precipitation was observed to mitigate SUHII variations globally, particularly in equatorial and arid zones.

Summary: The design of fairness and justice climate policies for controlling indirect household carbon emissions requires joint efforts from the demand side and supply side. This study constructs behavior-specific IHCEs inventory for different household groups in different regions and sets up Carbon Account for screening potential emitting-related stakeholders. The findings show that carbon inequalities across household groups are greater than income inequalities, and the top carbon-intensive consumption behaviors are Food & Beverage, Housing, and Durable goods. The study provides policy implications for local governments to mitigate high-emitting household consumption behaviors.

Summary: Although coal phase down has been recognized as crucial for climate objectives, there have been concerns over its impact on energy security and social development. Retrofitting coal power units with biomass and coal co-firing offers an alternative approach to mitigate these concerns and achieve negative CO2 emissions. This study focuses on helping China's coal power units make informed retrofit choices based on unit-level heterogeneity and resource spatial matching. The findings indicate that China has the potential to achieve significant negative CO2 emissions, with the cumulative total reaching 10.32 Gt by 2060.

Summary: Incorporating health cobenefits from coabated air pollution into carbon mitigation policy making is vital for enhancing policy efficiency in developing countries. However, the implications of sectoral mitigation policies on electricity demand and overall health impacts across regions and sectors remain unclear. This study examines the banning of internal combustion engine vehicles in China's private vehicle sector and finds that without carbon neutrality and air pollution control goals in electricity generation, the health benefits from the sector would be offset by increased electricity demand. Regional distributions of CO2 reduction and health benefits are highly unequal, with certain provinces experiencing greater impacts. Provinces in southeast China and the Sichuan Basin with consistently high health benefits per ton of carbon reduction are recommended to implement the ban policy first.

Summary: China's commitment and pathway towards carbon neutrality is crucial globally due to its status as a major economy with significant greenhouse gas emissions and ecosystem carbon sink. The integration of scientific knowledge from multiple disciplines is imperative to support policy-making on emission mitigation and carbon sink enhancement. This focus issue, along with a workshop on the same theme, provides an opportunity to meet this need, with 21 published papers presenting evidence of intensifying weather extremes, the potential of terrestrial carbon sink exploitation, and challenges and opportunities for emission mitigation.

Summary: Given the urgency of addressing climate change and declining demand for steel, it is important for China's iron and steel industry to phase out its primary production facility, the blast furnace. However, there is a lack of research on designing decarbonization pathways that consider economic, environmental, and regional aspects equally, as well as the impact of individual facility heterogeneity on climate policies. In this study, we propose a novel strategy to address these research gaps by considering economic, carbon, water, and health factors in determining the priority for closure of China's blast furnaces, aiming to improve environmental efficiency without sacrificing regional equality.

Summary: This study examines the economic and environmental effects of transitioning towards more circular food systems in the European Union (EU27) by feeding animals with low-opportunity-cost feed and better utilizing local feed resources. The results show that providing subsidies for circularity and promoting the use of low-cost feed can increase animal production, but also have negative impacts on land use and emissions. On the other hand, promoting domestic feed sourcing through import tariffs can decrease animal production and greenhouse gas emissions in agriculture. However, complementary policies are needed to mitigate drawbacks and enhance benefits of a more circular agri-food system.
