My eyes rolled when i saw that smug notice attached to an escalator. If they really gave a toss about environmental isses, they would have installed solar water heaters (yes they do work on cloudy days) on all that south facing roof space. Problem is that would involve long term investment with payback over several years and the beancounters are not too keen on that.
Also, what is the point of pretending to save the planet when they sell hundreds of thousands of plastic security bags in round plastic containers which go straight in the bin.
