Aviation Growth and Global Warming
pmi-media ltd., June 2007, Pages: 250
Aviation fuel efficiency measures “saving nearly 25 million tonnes of carbon dioxide a year”
Airline fuel efficiency measures, brought in to mitigate the rising cost of aviation fuel, have resulted in annual cut-backs of aircraft carbon dioxide (CO2) emissions of nearly 25 million tonnes, year on year. This represents annual savings of just over 4.0% of the total tonnage of CO2 aviation-related emissions. Potential annual cuts of a further 2% in the near term will also be possible if a range of new fuel saving intiatives – such as extending the use of winglets and ground-power units at airports – continue to be adopted throughout the industry.
“The UN’s International Panel on Climate Change (IPCC) and other studies which examine the forecast rise in aviation emissions generally accept that the industry will be able to make annual efficiency savings of between one and two percent,” according to one of the report authors Rainer Vogel.
“But these reports, based largely on aircraft data of a few years ago, do not take full account of the growth in information technology (IT) networks in which aircraft now fly. Aircraft now have the capability of flying dynamic routes to optimise fuel-efficiencies and match aircraft performance to prevailing weather data, unlike the fixed airway routes. This IT revolution has impacted on all aspects of air transport; from more precise flight briefings (so the pilot does not have to carry excessive reserves of fuel), to better flow control techniques (delays can be dealt with on the ground, with engines off, not in the air), better maintenance, repair and overhaul (MRO) (cleaner aircraft, better fuel performance) to better ATM, so aircraft can use jet-streams to minimise fuel burn and “glide approaches” into airports.”
Aviation growth and global warming examines the current state of the various programs aimed at exerting some measure of control over these issues, and provides detailed background information and analysis of the global warming issue as it relates to air transportation. It offers answers to the following questions:
-What are the key operating improvements available to aircraft operators seeking to reduce their annual fuel consumption bill?
-When will new aircraft, engine and other technologies become available aimed at reducing greenhouse gas emissions? What are these technologies?
-What will be the impact of emission trading schemes, and other regulatory initiatives, on airline greenhouse gas emissions?
-What is the range of current scientific opinion about the impact of aircraft operations on climate change?
-Which are the key research programmes which will deliver reduced greenhouse gas emissions at source?
-Which long-term proposals - for example, blended wing designs, formation flying, alternative fuels - offer the best opportunities to develop next-generation environmentally friendly aircraft?
-Which are the key enabling technologies - and investment opportunities - which will deliver improved fuel efficiencies in the near future? And which technologies are promising more than they will deliver?
