A recent study shows that although the aviation industry’s emissions targets are consistent with the overall targets of the Paris Agreement, the impact of aviation on the climate is likely to fall short of these targets. The aviation industry is an important contributor to the global economy, but its carbon dioxide (CO2) and non-CO2 effects (such as the formation of nitrogen oxides, ozone, and wake cirrus clouds) will cause global warming.

Researchers believe that as long as the aviation industry enters the recovery phase, restrictions on global air travel in response to the COVID-19 blockade will only have a temporary impact on the overall climate impact of the aviation industry. Today (June 22, 2021), an international research team including experts from the University of Birmingham published their findings in Nature Communications. They believe that non-CO2 effects will continue to be a major source of aviation’s impact on climate in the next few years. Influence to make a significant contribution. However, these effects are not included in the International Civil Aviation Organization (ICAO) climate-neutral growth goals, and Flightpath 2050 (European Commission’s Aviation Vision) only partially addresses these effects.
The researchers warned that despite the implementation of a series of mitigation measures by the aviation industry, the global warming effect caused by the aviation industry may still intensify between 2025 and 2064. Researchers say that improvements to engines, airframes, and operating technology are not enough to fully reduce the impact of aviation on climate change. We must also explore all mitigation options, including increased use of sustainable fuels and market-based measures to limit aviation’s environmental impact.
Researchers believe that the calculation of sustainable fuels must include the non-carbon dioxide emissions in use. If we base all calculations on carbon dioxide alone, we will miss the tremendous benefits that these fuels can provide in terms of non-carbon dioxide emissions. Improvements, especially in terms of reducing particulate emissions, which help increase the warming effect under cruising conditions.
