The rapid growth of global aviation emissions has significantly impacted the environment, leading to an urgent need use carbon reduction methods. This paper analyzes aviation's dioxide (CO2), N2O, and CH4 emission changes under different hydrogen energy application paths. warming potential over a 100-year period (GWP100) method is used convert N2O into CO2-equivalent. Here, we report results: if industry begins using turbine engines by 2040, it could reduce cumulative CO2-equivalent 2.217E+10 tons 2080, which 2.12% higher than starting fuel cell in 2045. However, adopting 10 years earlier shows greater capabilities engines, achieving accumulated 3.006E+10 emissions. Therefore, timing adoption notably affects more engines. Delaying makes engines' performance lag

Recently, aviation pollution has drawn important social attention. The protocol proposed in this paper can simultaneously calculate the overall emissions of six pollutants (CO2, CO, HC, NOx, SO2, and PM2.5), including landing take-off climb/cruise/descent emissions. international routes South America during 2019-2021 are an example to illustrate use protocol. This provide a methodological basis for calculating pollutant different countries regions. For complete details on execution protocol, please refer Cui et al. (2022b).1.

This article calculates the carbon emissions from China-foreign and India-foreign routes in 2019. The error rate of China's India's external is about 2.75% 5.21%, respectively. First, it obtains aircraft with least emission intensity each distance segment. Then, we use lowest to replace original compare reduction. results show that after reconfigured, CO2 has declined by 57.08% 35.45%, Interestingly, average costs also dropped 8.04% 39.39%, respectively, reconfiguration. Therefore, fleet schedule reconfiguration one most feasible ways for airlines reduce emissions. However, increased costs, only when price eight times current level can they offset increase costs.

As important nodes in the air transport system, it is of great significance for airports to achieve carbon-peaking goal before 2030 under target peaking carbon emissions China’s civil aviation industry. However, remains unknown whether will be able realize this ambitious due a variety uncertain factors, such as social economy, epidemic impact, and emission reduction measures. According possibilities 12 scenarios were constructed. Using case Guangzhou Baiyun International Airport (CAN), study predicted medium- long-term trends based on Long-range Energy Alternatives Planning System (LEAP) model. Furthermore, effects abatement measures responsibilities analyzed. The results show that CAN cannot guarantee established policy. If socioeconomic development rapid, peak at about 90 kt tons 2030, if slow, plateau 1 million between 2035. What more, airlines bear greatest responsibility reducing emissions, technological progress have highest potential. This provides decision support airport stakeholders work so ensure can goal.

The aviation sector is believed to be responsible for considerable environmental damage attributed emission of a large number and amount pollutants. Airports are often surrounded by forest fragments humid areas that attract birds prey hence may potentially serve as useful bioindicators. aim the present study was examine genotoxic potential in raptors exposed airport pollution using micronucleus (MN) test morphological changes evidenced bilateral symmetry. This investigation conducted at Salgado Filho International Airport Porto Alegre – RS well private zoological breeding grounds. presence metals measured blood cells collected birds. Seventeen (Caracara (Polyborus) plancus) were used this 11 from 6 non-exposed group. nuclear alterations clearly indicate organisms exhibited significantly higher frequency genetic compared Further, manganese chromium detected exclusively In contrast, analysis symmetry did not detect any significant morphologic differences between two groups. Therefore, data stress occurs living civil MN increase chromium.
