Greenhouse gas emissions from commercial air travel is a major contributor to global warming emitting approximately 700 million metric tons of carbon dioxide (CO2) in 2012 alone.
A new report from the International Council on
Clean Transportation (icct) (www.theicct.org)
Fuel efficiency trends for new commercial jet aircraft: 1960 to 2014 has
explored the fuel efficiency in relation to UN targets.
It shows that aviation fuel use, including military
aircraft, quadrupled between 1960 and 2006.
While most countries are agreeing to 80% reductions in emissions by 2050,
aviation fuel use is expect to increase by 300% over the same period. The report explores how efforts to increase
fuel efficiency of aircraft is continuing having already achieved an annual
rate of reduction of 1.3% since 1968. Between 1968 and 2014 the average fuel burn of new aircraft fell
approximately 45%, or a compound annual reduction rate of 1.3%. However, the efficiency of new
aircraft are still a decade behind the United Nations’ fuel efficiency goals
for new aircraft.
