It is a known fact that planes are one of the most polluting means of transport that exist, but even that sector also reaches the movement of sustainability and awareness.
Airlines are investing millions in making their journeys as less pollutant as possible. Paying an extra for the carbon footprint or allocating it to environmental projects, an entire flight without plastic waste or using ecological packaging are some of the initiatives that some airlines have begun to carry out.
Although many travelers decide not to take the plane by conviction, it remains a means of transport of high occupancy and essential in many situations. That's why society itself is also pushing to accelerate these changes.
