This has to be the dumbest thing we’ve read in quite some time.

A Japanese airline has started asking passengers to go to the toilet before boarding in a bid to reduce carbon emissions.

No, seriously …

All Nippon Airways (ANA) claims that empty bladders mean lighter passengers, a lighter aircraft and thus lower fuel use.

And in case you were wondering, because we were:

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.

Let us get this straight: An average 737 aircraft weighs 187,700lbs. and this company is worried about 63.7kg [140lbs.]?

Brilliant.
