I speak as a climate change sceptic, but have no intention of rehearsing the arguments here. Nonetheless, my view is that "green" policies do no harm, the worlds resources are finite and the developing world aspires to our standard of living. There are insufficient resources for the entire worlds population to live the western lifestyle, yet more and more are doing so. We have to find a way to make those resources go further. I may not agree on the cause but the green initiatives' central aim is to consume less, stretching valuable resources.

Now, I think if we're really to believe that these cards imploring us not to have linen changed or towels replaced are anything more than a cost-cutting exercise modelling in a green dress, we need to visibly see other efforts. The cards have been in the rooms for years, yet no other evidence of "green" policies are visible. Hardly surprising they're viewed with such scepticism...

I realise for a hotel brand such as Marriott it's very difficult to display the efforts being made, lots of garish coloured bins in every room are hardly going to be popular, nor are directives around the hotel, or shutting off aircon, nor cutting carparking spaces, but if we are to be implored to "join in" with Marriott here, we as guests need to see something happening to "join in" with.
