TRL3703ASSIGNMENT 5
SEMESTER 2
2023
Q1 In recent years the term sustainability has gained significant attention as people become
more conscious of the environment due to the rising occurrences of climate related events.
, The aviation sector, a substantial contributor to environmental degradation within the
transportation industry, has come under scrutiny for its role in exacerbating these issues.
Critically discuss the types of environmental issues related to air transport. Incorporating
pertinent examples where applicable.
In recent years, the aviation industry has been under increased scrutiny due to its
environmental impact, as people become more conscious of the environmental issues
associated with air travel, driven in part by rising occurrences of climate-related events. This
industry, while integral to the global economy and progress, has significant environmental
implications. This question explores the environmental challenges posed by air transport,
1. Local Environmental Issues (as mentioned in Whitelegg 2000):
a. Noise Pollution:
Noise pollution is a prominent local issue associated with airports and flight paths, as
discussed in Whitelegg (2000). Residents living near airports or directly under flight paths are
exposed to elevated levels of noise pollution, typically measured on the decibel "A" scale
(dB(A)). For example, a noise level of 70dB(A) can be loud enough to disrupt normal
communication. Noise pollution can lead to a range of adverse effects, including hearing
impairments, sleep disturbances, and reduced overall quality of life for affected residents.
Additionally, it can result in additional costs for airlines, airports, and governments as they
invest in noise mitigation measures.
For example
The issue of noise pollution near airports is exemplified by London's Heathrow
Airport, one of the world's busiest. The constant noise generated by aircraft
movements has led to protests and demands for noise reduction measures. A study
published in the International Journal of Environmental Research and Public Health
(2019) assessed the impact of noise pollution from Heathrow Airport on residents'
stress levels and overall quality of life, providing empirical evidence of its negative
consequences.
One of the environmental concerns associated with SAA's operations is noise
pollution, especially at airports like OR Tambo International Airport in Johannesburg
and Cape Town International Airport. Communities living near these airports have
raised noise-related issues, including disturbances during nighttime flights. The noise
has prompted discussions and efforts by SAA to implement noise abatement
procedures, such as adjusting flight schedules to minimize disturbances during
sensitive hours.
