British no-frills airline easy Jet recently made initial steps to reduce its carbon footprint, offsetting emissions from all flights in an industry first -- and revealing research into greener engines.
"I am proud that we have announced that from today we will be the world's first major airline to operate net-zero carbon flights across our whole network," said Chief Executive Johan Lundgren in a results statement.
"We are doing this by offsetting the carbon emissions from the fuel used for all of our flights.
"We recognize that offsetting is only an interim measure, but we want to take action on our carbon emissions now."
The carrier announced the news, expected to cost it around £25 million ($32 million, 29 million euros) in 2020, alongside a modest drop in annual profit as the short-haul sector faced challenging trade.
