A Japanese Airline has started asking passengers on some of it’s flights to use the restroom prior to boarding the plane.
This strange request is one of the measures the airline is taking to reduce fuel consumption.
All Nippon Airways has estimated that if half it’s passengers went to the bathroom before boarding they could reduce their carbon dioxide emissions by 4.2 tons per month.
The airline also plans to recycle paper cups, plastic bottles and use chopsticks that were produced from wood from forest thinning projects in order to become more environmentally friendly.
These measures are being taken on 38 domestic flights and four international flights throughout October.
The move follows earlier steps by airlines to reduce the weight of flights by trimming the size of in-flight magazines, slimming the handles of forks and spoons and using lighter drink trolleys and porcelain.
It is not the only airline looking to the lavatory to save money. Irish budget airline Ryanair has previously said it is considering charging passengers to use on-board toilets.
