The Impact of Different Aircraft Categories on Emissions, Air Quality, and Human Health

Previous studies have estimated that over 16,000 annual early deaths are induced by global aviation emissions. Combined with a growing industry, this calls for sustainable developments to reduce the negative impact on human health. However, the potential application of more sustainable technologies varies amongst aircraft size and range. Thus,...

The Quest for TROPOMI-Observed En-Route Aviation NOx Emissions

In this work the possibility for use of the satellite remote sensing instrument TROPOMI to detect NOx emissions from en-route aviation is assessed. Analysis of aviation intensity, quality of satellite retrievals, and emissions from non-aviation anthropogenic sources showed that the North Atlantic, including the North Atlantic Flight Corridor,...

Analysis of Climate Metrics for Aviation

The aviation industry continues to contribute to anthropogenic climate change. Recent studies have shown that the total radiative forcing from aviation is around three times higher than that from CO₂ alone. To account for the full effect of aviation, climate metrics are needed, which equate the environmental impact of various...

Quantifying the impact of aviation emissions on global nitrogen deposition

Excessive nitrogen deposition from anthropogenic emissions has a global impact on natural biodiversity. While aviation emissions have been studied in the context of climate change and air quality, this is not true for nitrogen deposition. Meanwhile the growth of the aviation industry is likely to increase the relative contribution of aviation...
