Norwegian has made an ambitious 10-year pledge to almost halve its carbon emissions compared to 2010 levels.
The airline, through its new sustainability strategy, will seek to reduce emissions by 45% in the 10 years to 2030.
Its aim is to reduce its carbon output in line by what is required by the Paris Agreement on carbon to limit global warming to 1.5%.
Other pledges in the strategy include removing all non-recyclable plastics, and recycling all single-use plastics.
Chief executive Jacob Schram said Norwegian’s low-cost model was a model for sustainability as it encourages more stringent resource management and energy efficiency targets.
"Norwegian will continue to instigate a positive change across the industry in this field that will benefit not only the environment but also our customers and our business," Schram added.
Norwegian’s overall aim is to reduce emissions by 45% per passenger kilometre when compared to 2010 levels, which it says it will achieve through investment in more energy efficient aircraft, and a switch to more sustainable aviation fuels.
It has committed to using between 16% to 28% sustainable aviation fuel by the end of the decade, depending on the composition of its fleet.
Schram said it was vital there was a regulatory framework that rewarded carbon efficiency, as as well as production and use of sustainable fuels.
“We encourage producers to ramp up production of sustainable aviation fuels," said Schram.
"Norwegian will be actively engaging with producers to kick-start this vital contribution to the industry and take advantage of the emission savings that these fuels offer.”
Meanwhile, Norwegian intends to achieve its pledges on plastics by 2023.
