The Church of England has issued The Ten Green Commandments, which include sharing cars, using energy saving bulbs and taking local holidays. I know they have done this, because I heard it on Radio Two's news. That was during the Alan Titchmarsh programme. (Hello? I can't believe I am listening to Alan Titchmarsh). But can I find the story on the web? I cannot.
Anyway, well done CofE, and I am preparing to have a guilty flurry of activity.
