Save as WWF, Save a Tree.

The WWF format is a PDF which cannot be printed out. Clever, huh? Now you can keep others from killing trees.

The idea is simple. If you want to send a PDF to someone but you feel bad if they print it out, WWF has the answer for you.

The WWF format is a small programme which lets you save your files in a unprintable way. You can download the programme here.

There are quite some other possibilities to impose a certain sustainable lifestyle on the people surrouding you. What about turning off the warm water when your flatmates shower for too long? I am sure there are other possibilities which will not affect your relationships negatively. Why not offering to do your washing together in order to really fill up the machine and not waste any energy? Or how about eating together? Cooking twice means twice as much energy use.

Something else which made me smile this morning:

German “knowing/doing/buying -better” homepage Utopia  praises a rather surprising good:

They offer “Nothing” in the top of the “buy-better” section. They explain: “Nothing is as sustainable as…nothing. It’s CO2 neutral, it doesn’t take a lot of space and it lasts forever.” Visit their homepage to find out more about this amazing product and many more good ideas.
