“…Similarly, for the air pollutants CO, PM and SO 2 , the results of this study were higher than those of [28,50,56,57], which were 3-126%, 16-290% and 127-1381%, respectively. For the LTO phase, the CO 2 emissions were 20% higher than the results of [58], for the air pollutants CO, PM, SO 2 and NOx, the results of this study were higher than those of [18,58], which were 41-77%, 100-300%, 58-533%, 0.85-57%, respectively. The reasons for the differences may be attributed to the following: (1) Interannual variation in activity levels, as the emission inventories in these studies were established 0-8 years prior to this study, which can explain the annual increase in pollutant emissions.…”

Civil aviation transport is a key area of fossil energy consumption and greenhouse gas emission, and it is also an important source of air pollutants; the emissions of these have caused severe environmental problems. In this paper, we estimated the emissions in 235 domestic civil airports, and predicted the future trends of CO2 and air pollutant emissions from civil aviation in China until 2050 under three scenarios. The co-reduced emissions of each measure were evaluated by using the co-control effects coordinate system. The results show that in 2018, the emissions of CO2, NOx, SO2, CO, PM and HC were 117.23 × 106 tons, 90.47 × 104 tons, 14.37 × 104 tons, 9 × 104 tons, 1.29 × 104 tons and 0.66 × 104 tons, respectively. CO2, NOx, SO2 and PM emissions were mainly concentrated in cruise mode, accounting for 87–93% of the total emissions; HC and CO emissions were more frequently from the LTO. Under the baseline scenario, the growth rate of air pollutant emissions will account for a greater share, from 84% in 2030 to 464% in 2050, whereas the general scenario reduces emissions by 15% and 71%, respectively, and a higher reduction of 26% and 93% is seen in the stringent scenario. Improving aviation fuels is the most significant co-reduction measure, which can reduce CO2 by 89% and 68% in 2030 and 2050, and reduce air pollutants by 86–89% and 62–65%, respectively.

“…The assessment of emissions generated by aircraft at ground level is largely described in the literature from different points of view. Specific assessments due to Landing and Take-Off (LTO) cycles in several case studies are available, stressing the relevance of including specific parameters such as the detailed flight information and the dynamic time in climb and approach modes [8], aircraft fleets performance and payload [9], availability of runways [10], considering specific inventories [11,12], large-scale benchmark [11,13,14], or case-specific assessments. All highlight how LTO operations might affect air quality and increase noise levels, eventually impacting public health [15,16].…”

The environmental concerns are behind urban and regional mobility plans, with one of the goals being to manage surface traffic to reduce emissions. Yet, in sensitive areas such as those around airports, the contribution to the emissions generated by air traffic are commonly not considered. The research goal of this paper is to quantify and compare the magnitude of the emissions generated by both air and surface traffic, taking the second airport in Rome as an example, in the awareness that a proper knowledge of the emission phenomena might help steer local transport policies towards more appropriate and sustainable solutions. The paper describes the case study’s regulatory and land use frameworks both affecting the current traffic patterns around the airport and the emission generation, along with the methodology adopted to quantify the emission magnitude of both air and surface modes; as a result, air traffic emissions are not even comparable in magnitude to those from surface modes. In light of that, implications for surface transport policies are presented, leading to a revision of current mobility plans, and solutions to minimize emissions during land and take-off operations suggested, although problems for their implementations are acknowledged in the conclusions. All within the additional goal to advance the research further afield.

“…It was found that monthly and daily emissions do not vary significantly. Yu et al ( 2021 ) analyzed the trend of AEEs at some airports in mainland China from 1970 to 2017 and found that the average emission per passenger has declined for the duration. Bao et al ( 2021 ) revealed some simple regional distribution of AEEs from LTO cycles during the pandemic but failed to thoroughly compare the AEEs at airports in 2020 to the year when the pandemic had not yet occurred.…”

“…Accordingly, this study intends to explore the positive environmental impacts of travel restrictions from the perspective of AEEs at the ground level. Although several researches have focused on the estimation and analysis of AEEs from LTO cycles at both the local scale (Yılmaz 2017 ; Kuzu 2018 ; Tokuslu 2020 ) and the regional scale (Kesgin 2006 ; Hu et al 2020 ; Yu et al 2021 ), the research on AEEs from LTO cycles in the context of the COVID-19 pandemic is still scarce. Furthermore, there has never been any analysis of the relative change in air pollution at airports between the COVID-19 era and the pre-COVID-19 era, either from a temporal or spatial perspective.…”

Aircraft engine emissions (AEEs) generated during landing and takeoff (LTO) cycles are important air pollutant sources that directly impact the air quality at airports. Although the COVID-19 pandemic triggered an unprecedented collapse in the civil aviation industry, it also relieved some environmental pressure on airports. To quantify the impact of COVID-19 on AEEs, the amounts of three typical air pollutants (i.e., HC, CO, and NO x ) from LTO cycles at airports in central eastern China were estimated before and after the pandemic. The study also explored the temporal variation and the spatial autocorrelation of both the emission quantity and the emission intensity, as well as their spatial associations with other socioeconomic factors. The results illustrated that the spatiotemporal distribution pattern of AEEs was significantly influenced by the policies implemented and the severity of COVID-19. The variations of AEEs at airports with similar characteristics and functional positions generally followed similar patterns. The results also showed that the studied air pollutants present positive spatial autocorrelation, and a positive spatial dependence was found between the AEEs and other external socioeconomic factors. Based on the findings, some possible policy directions for building a more sustainable and environment-friendly airport group in the post-pandemic era were proposed. This study provides practical guidance on continuous monitoring of the AEEs from LTO cycles and studying the impact of COVID-19 on the airport environment for other regions or countries.
