An Assessment of Singapore Airlines Environmentally Sustainable Energy Management

Abstract

This study has examined how Singapore Airlines, a major global airline, manages its energy in an environmentally sustainable manner. The research used an in-depth qualitative longitudinal research design. The study period was from 2010/2011 to 2020/2021. Singapore Airlines four key energy sources are aircraft jet fuel, electricity, diesel, and petrol. The airline's passenger aircraft jet fuel consumption grew in line with its expansion of services and aircraft fleet. The airline's freighter aircraft fleet consumption exhibited a general downward trend. The annual electricity consumption displayed a general downward trend and benefited from the energy saving measures introduced by the airline over the study period. Diesel consumption grew in line with ground service equipment (GSE) energy requirements. The airline's annual petrol consumption fluctuated over the study period reflecting differing fuel requirements. Throughout the study period, Singapore Airlines implemented many energy efficiency measures. These measures include an aircraft weight reduction program, the installation of extensive light emitting diode (LED) lighting, the installation of more energy efficient plant and equipment, the installation of more energy efficient heat exchange system at its Silver Kris Lounge at Changi Airport, the upgrading of lifts with a more efficient model that had a Variable Voltage Variable Frequency (VVVF) motor, the installation of a large scale photovoltaic (PV) system, a computer system that optimizes the maximum zero fuel weight (MZFW) of its aircraft fleet, the use of lightweight catering items, the use of light weight aircraft containers, the use of sustainable aviation fuel, and the use of fixed electrical ground power and preconditioned air units at airports where its aircraft have night layovers or long transits.

A critical review of energy consumption and optimization strategies in the Nigerian aviation sector: challenges and prospects

“…Historically, this has been provided by onboard auxiliary power units (APUs) which burn jet fuel. However, many modern airports, in a bid to reduce emissions, are transitioning to ground power units (GPUs) which provide electricity to aircraft from the airport's main power grid (Altuntas et al 2014;Baxter 2021Baxter , 2022Padhra 2018). Yet, in Nigeria, with its irregular power grid situation, this transition is not straightforward.…”

Hedging Strategy and Financial Analysis of Singapore Airlines

“…Generally, the SIA has hedged a large amount of fuel and crude oil demand, although it has been in the red for a long time. One possible reason for the high hedging amount is that jet fuel consumption growth from 2010 to 2021 is in line with the group's expansion of services and aircraft fleet [8]. As the Covid-19 virus is being dealt with globally, the gains from fuel hedging have climbed.…”
