A Japanese airline has started asking passengers to go to the toilet before boarding in a bid to reduce carbon emissions.
All Nippon Airways (ANA) claims that empty bladders mean lighter passengers, a lighter aircraft and thus lower fuel use.
Airline staff will be present at boarding gates in terminals to ask passengers waiting to fly to relieve themselves before boarding, The Independent reported.
ANA hopes the weight saved will lead to a five-ton reduction in carbon emissions over the course of 30 days.
The airline began the policy on October 1, according to Japan’s NHK television.
Although it is intended as an experiment lasting one month and 42 flights, the trial may be extended if it is well-received by passengers and if results are positive.
Based on an average human bladder capacity of 15oz, if 150 passengers relieved themselves on board an aircraft, this would amount to 63.7kg of waste.
