The Eco Green Flag

This is the flag that is awarded to schools, who have managed to achieve a certain level in the reduction in the amount of waste that they use (e.g. recycling paper, turning off lights/computers etc to save energy). I, however, don't know how much you have to reduce your waste by before you are awarded this flag. Not sure whether this scheme is just available in Scotland, or whether it's available in the rest of the UK.
