Airlines are trying hard to improve their environmental credentials but All Nippon Airways' latest effort might make a few people laugh or maybe not.
ANA - supposedly in the interests of the environment and limiting carbon dioxide emissions- is asking passengers to go to the toilet before boarding.
The initiative is part of its "e-flight" programme to reduce the amount of carbon dioxide expelled on its flights.
Other initiatives under the programme include using recycled paper cups and plastic bottles instead of glass.
I think it is questionable how effective such initiatives are. To really make a difference, there has to be further development on aircraft engine technology and airlines need to get regulators to approve more efficient flight paths. Saving on toilet paper isn't going to do the trick.
