- What is Environmental Impact of Aviation?
- What is Green aero-engines?
INTRODUCTION
Aviation industry produces huge amount of green house gases due to which environment gets severally affected. The extent to which aviation industry harms the environment can be seen from the fact that this industry is responsible for emitting approximately 2.5 percent of global CO2 emission. Due to much feasibility of air travel, people are now able to travel via aircraft easily. This increased feasibility has affected the condition of environment adversely because an aircraft consumes lot of energy due to which it has to relied on fuels which posses high energy density. These dependency of aircraft on fuels is the major cause behind the adverse impact of aviation industry on environment. However, the rapid development has made alternative carbon fuels named sustainable aviation fuels or SAFs that facilitates aviation industry in reducing its negative effect on environment (Kılıç, Uyar & Karaman, 2019). The aim of this report is to identify the environmental impact of aviation. This report will further highlight the technologies or methods to mitigate the aviation impact on environment.
Potential to reduce the climate effect of aviation by climate restricted airspaces
According to Niklaß, the major concern regarding the aviation industry is the impact of commercial aircraft operations on the environment because it emits large heavy amount of Nox, CO2 along with the formation of contrails. There are several mitigation strategies with the help of which unfavourable impact of aviation on environment can be mitigated but it will be difficult to implement these strategies in near future due to Science Research Topics numerous technical challenges. Moreover, the air traffic operations impact the climate by emitting water vapour, carbon dioxides, nitrogen dioxides and aerosols. The latter one stimulates the ozone formation and methane depletion which are the significant greenhouse gases. Climate restricted airspace is an effective approach through which the adverse effect of aviation on environment can be reduced. This approach emphasises on closing of climate sensitive regions for a certain time period and impacted flights are re-routed around them. This strategy can be implemented quite easily in the near future unless the more feasible strategies are available. Addition to this, a simulation framework has also been developed in order to assess the economic and ecological aspect of this interim mitigation strategy. It has also been identified that introduction of ATM charges for flights through climate sensitive regions is also possible rather than closing those regions fully. &n
