The quest to mitigation of aviation emissions and pollutions

Abstract

With the aviation industry's continuous development and commercial air travel's growing popularity, the emissions and pollution resulting from air transportation have experienced a rapid surge. In recent years, as environmental awareness has increased and there has been a growing reflection on the pollution caused by technology, the significance of aviation emissions has been increasingly acknowledged. This article aims to summarize achievements and challenges concerning the current state of aviation emissions and the technologies employed for their reduction. It begins by outlining the present state of aviation emissions, followed by an analysis of common pollutants emitted by the aviation sector, such as NOx, CO, and HC, as well as the mechanisms underlying greenhouse gas emissions and their associated hazards. Furthermore, the article explores several prevalent emission reduction strategies, including applying biofuels, improving combustion chambers, and optimizing flight procedures. Finally, the article provides an outlook on potential future directions for aviation emission reduction technologies.
