By Air Marshal Anil Chopra (Retd) The terms ‘Sustainable Aviation’ or ‘Green Aviation’ are increasingly being used to address the technological and socio-economic issues facing the aviation industry to meet the environmental challenges of the twenty-first century. As air travel notches high growth, global aviation contributes about two per cent of global greenhouse gas emissions yet it supports eight per cent of the world economic activity. By 2025, it is estimated that the total CO2 emission due to commercial aviation may reach around 1.5 billion tonne. Aircraft noise may affect from 24 million in 2000 to 30.5 million by 2025. Therefore, there is urgency to address the problems of emissions and noise abatement through technological innovations. New aircraft and engine designs/technologies must look at

engine fuel efficiency to carry more passengers and payload for lesser fuel burn. The commercial aircraft turbofan engine market is dominated by a handful of major global players namely Pratt & Whitney, Rolls-Royce, General Electric (GE) Aviation and Safran. GE and Safran of France have a joint venture, called CFM. As per the report released by global business data platform ‘Statista’ in May 2021, CFM International had 39 per cent market share of the commercial aircraft engines in 2020.
