Summary: This study focused on carbon emissions in the Beijing-Tianjin-Hebei region, revealing the need for tailored emission reduction policies due to differing industrial characteristics among cities. High carbon emission cities include Tangshan, Handan, and Shijiazhuang, while low carbon emission cities include Hengshui, Baoding, Langfang, Qinhuangdao, and Xingtai. Factors such as economic scale, energy intensity, and energy structure contribute to variations in carbon emissions, highlighting the importance of individualized emission reduction strategies for each city.

Summary: China's air pollution policies prioritize differences between cities and emphasize coordinated control of pollutant emissions between cities, particularly in the context of supply chains. In examining the Beijing-Tianjin-Hebei urban agglomeration in China, it is found that nitrogen oxide (NOx) emissions are primarily concentrated in Tangshan and Beijing, with the electricity and heat, metal, and nonmetal sectors being the main suppliers in the NOx supply chains. The transfer pattern of NOx between cities in this region is generally efficient, extending from low- to high-emission intensity cities, while the pattern between cities in this region and other provinces is opposite. The results reveal the potential for emission reduction at the city level, with a focus on reducing the emission intensity of production-oriented cities in the Beijing-Tianjin-Hebei region.

Summary: This paper decomposes the factors causing changes in carbon emissions from direct energy consumption in the construction industry in Beijing-Tianjin-Hebei using the logarithmic mean divisia index (LMDI) method. It analyzes the effect values and contribution rates of each macrofactor. Based on the decomposition results and relevant national policies, five scenarios are set up for each influencing factor, and scenario prediction is conducted using regression stochastic impact on population, affluence, and technology (STIRPAT) with ridge regression analysis. The results provide insights into the future time of carbon peaking and carbon neutrality in the construction industry of Beijing-Tianjin-Hebei.

Summary: Stringent mitigation measures have reduced wintertime fine particulate matter (PM2.5) concentrations by 42.2% in the Beijing-Tianjin-Hebei (BTH) region from 2013 to 2018, but severe PM pollution still frequently engulfs the region. The contributions of nitrogen oxides (NOX) emissions mitigation to nitrate and PM2.5 concentrations remains elusive, with simulations showing a 50% reduction in NOX emissions actually increasing PM2.5 concentrations. Mitigation of NH3 emissions is identified as the priority measure to effectively lower nitrate and PM2.5 concentrations in the BTH under current conditions.

Summary: Analysis of the driving mechanism of wetland change can help understand the spatial differences among different factors and provide scientific strategies for wetland conservation and utilization. Using the Beijing-Tianjin-Hebei Plain as a case study, we examined the temporal and spatial changes of wetlands over four different periods. By establishing a wetland change evaluation system and utilizing a random forest model, we identified the main drivers of wetland change from 1990 to 2020. Based on our findings, we proposed specific protection policies according to different zones.

Summary: Using reanalysis and observation data, this study investigates the impact of sudden stratospheric warming (SSW) events on air quality in the Beijing-Tianjin-Hebei region. The study finds that SSW events, especially split SSWs, have a significant impact on atmospheric particulate concentration in the region. The concentration is low before the SSW onset, increases around the SSW onset, and decreases during the SSW decay period. The study also discusses the meteorological conditions during SSWs and their influence on air pollutant levels.

Summary: Heavy-duty diesel trucks (HDDTs) cause serious pollution to urban and regional environments. This study constructs a multiscale NOx emission inventory of HDDTs with high spatiotemporal resolution in the Beijing-Tianjin-Hebei region and analyzes the spatiotemporal variations using spatial statistical indicators and a multiscale geographical weighted regression model. The results show different distribution and aggregation characteristics of NOx emissions at different scales, with spatial heterogeneity and multiscale effects of socioeconomic and road attribute characteristics. Population density, urbanization rate, proportion of second industry, and proportion of highway affect the NOx emissions of HDDTs globally, while per capita GDP and road density have local effects.

Summary: In China, road traffic carbon emissions and their share in total carbon emissions have significantly increased. The Beijing-Tianjin-Hebei region, the largest urban agglomeration in northern China, is receiving more attention. This study presents computational models to calculate road traffic carbon emissions in different cities and intercity traffic arteries based on the road network. The results show that Beijing has the highest road carbon emissions, almost three times that of Shijiazhuang. Commuting increases weekday traffic compared to weekends in Tianjin, Shijiazhuang, and Beijing. The intercity road has a daily traffic flow of about 1.92 million vehicles, resulting in total carbon emissions of 22.97 million t CO2. The study also evaluates the potential reduction of carbon emissions in Beijing.

Summary: The green growth of the Beijing-Tianjin-Hebei urban agglomeration has a leading and exemplary role in overcoming resource restrictions, addressing climate change, and supporting high-quality growth in China. This paper evaluates the environmental impact and decomposes the drivers using the Logarithmic Mean Divisia Index (LMDI) model and a decoupling effort index. The results show that Beijing has the lowest environmental impact index, while Tianjin and Hebei are primarily influenced by environmental regulation and energy intensity, respectively. Strong decoupling efforts are found in all regions, with Beijing being the most significant. According to the forecast, the BTH area will maintain a strong decoupling effort, with Beijing having the highest index and Hebei the lowest.
