Summary: Public transport, especially Bus Rapid Transit (BRT) systems, is popular for time management in daily activities. In BRT systems, buses often gather at stations during rush hours, leading to high emissions during take-off motion. A study on the Istanbul BRT system found that an acceleration limitation based on weight and road grade could have positive effects on reducing harmful emissions.

Summary: Plug-in hybrid electric vehicles (PHEVs) are considered favorable transitional technology for road transport electrification. However, recent studies challenge their effectiveness in reducing CO2 emissions in real-world conditions. This study tested four Euro 6 PHEVs and found that their in-use CO2 emissions can range from 0 to 6 times the official type-approval CO2 value. A three-dimensional CO2 emissions model is proposed based on charge level and average trip speed or wheel energy. The study concludes that, although real-world emissions of PHEVs may increase compared to official values, they still generally remain lower than conventional powertrains.

Summary: China’s emission control for nonroad diesel mobile machinery (NDMM) faces challenges of rapid stock increase and outdated regulations. This study provides a comprehensive review and evaluation of China’s NDMM policies, along with emission measurements and investigation on diesel fuel quality. The shift from China II to China IV standards greatly improved the control of NOx and PM emissions, but non-type-approved engines still exceeded the limits. The policies on new and in-use NDMM, as well as diesel fuel quality, contributed to reducing NOx and PM emissions and enhancing the competitiveness of China’s NDMM industries.

Summary: The lockdown policy in China during the spread of coronavirus in early 2020 severely impacted the economy and led to a significant reduction in nitrogen oxides (NOx) emissions. Satellite observations showed a sharp drop in nitrogen dioxide (NO2) levels, followed by small fluctuations and a strong rebound compared to 2019. The rebound of NO2 was mainly driven by the rapid economic recovery, particularly in the industrial and power sectors. This indicates that the emission reduction during the lockdown was offset by the economic recovery, highlighting the need for further efforts to promote low-pollution development.

Summary: Previous studies have mainly focused on agricultural ammonia emissions and neglected the impact of vehicular ammonia emissions on air quality in cities. This study developed high-resolution emission inventories for Beijing and Shanghai based on traffic data and simulated the contribution of vehicular ammonia emissions to PM2.5 concentrations. It was found that vehicular ammonia emissions accounted for a significant proportion of total anthropogenic ammonia emissions in urban areas, and could contribute to approximately 3% of urban PM2.5 concentrations during winter. Controlling vehicular ammonia emissions is an effective measure to mitigate urban PM2.5 pollution in the future.

Summary: Over the past decade, Beijing has upgraded its emission standards and fuel standards, improved vehicle structure by accelerating the elimination of old vehicles, and implemented policies to reduce the emissions of air pollutants. The results show that the emissions of four air pollutants from vehicles in Beijing decreased significantly in 2019, with the contribution of nitrogen oxides from diesel vehicles increasing. To further improve pollution control, it is necessary to promote clean and energy-saving diesel vehicles and adopt electric vehicles to reduce pollutant emissions. By the end of the 14th Five-Year Plan period, it is expected that the total emissions of the four vehicle pollutants can be further reduced.

Summary: Vehicle emissions in China have been successfully decoupled from rapid motorization through comprehensive control strategies. The emission ratios of THC and NOX can vary dramatically among different seasons and provinces. While CO, THC, and PM2.5 emissions have decreased, the controls of NOX and NH3 emissions have been less efficient. Future reductions in emissions are anticipated through the deployment of new energy vehicles and stricter emission standards.

Summary: China has made significant progress in the electrification of passenger cars, with sales of battery electric vehicles (BEVs) surpassing 10%. A life-cycle assessment (LCA) method was used to estimate the carbon dioxide (CO2) emissions of past, present, and future BEVs, taking into account China's carbon peaking and neutrality policies. BEVs can reduce cradle-to-grave (C2G) CO2 emissions by approximately 40% compared to internal combustion engine vehicles (ICEVs) at the national-average level in 2020, and further reduction is expected by 2030 through cleaner electricity mix and advancements in battery technology and related metal materials.

Summary: Current chemical transport models fail to accurately simulate the concentrations and temporal variations of organic aerosol (OA), specifically secondary organic aerosol (SOA), due to the exclusion of intermediate-volatility and semivolatile organic compounds (I/SVOCs) as precursors. This study incorporates a high-resolution emission inventory of I/SVOCs into the CMAQ model to simulate the concentrations, temporal variations, and spatial distributions of POA and SOA from different sources in the Yangtze River Delta (YRD) region. Results show that including I/SVOC emissions leads to significant improvements in SOA concentrations, with cooking emissions being the primary source of POA and industrial emissions being the dominant contributor to SOA formation. These findings highlight the need for tailored control measures and updated source profiles to improve air quality in the region.
