A digital carbon calculator will enable consumers to offset emissions on Ryanair flights.
The new feature will calculate the carbon emissions per passenger on every route and allow customers to pay the full carbon cost of their flight, contributing to environmental initiatives.
The no-frills carrier currently enables passengers to contribute €2 towards carbon offset projects.
The contributions support environmental initiatives, including a reforestation project in the Algarve; the distribution of energy-efficient cook stoves in Uganda; a wind power project in Turkey and improved kitchen regimes in Malawi.
More than customers €3.5 million has bee contributed to environmental projects to date.
The airline aims to power 12.5% of its flights with sustainable aviation fuels by 2030 together with a $22 billion investment in new Boeing 737 Max aircraft to cut CO2 and noise emissions over the next decade.
Ryanair hopes to achieve its aim of being a carbon neutral airline by 2050.
Director of sustainability Thomas Fowler said: “Hundreds of thousands of Ryanair customers every year are already choosing to contribute and support the environment by selecting carbon contribution at their time of booking.
‘The expansion of our carbon offset scheme to enable our customers to fully offset the CO2 of their flight will greatly enhance the capabilities of each of our environmental partners who are actively working on carbon offsetting programmes.
“Sustainability and environmental impact are considered in every business decision made in Ryanair and we are truly dedicated to being a net carbon neutral airline by 2050.”
