KEY POINTS:
What are you doing personally to make a difference?
I've switched off the heated towel rail at my home at the North Pole. Mrs Claus grumbles a bit but I tell her we're doing our bit to save the Arctic ice floe.
What more could you do?
I suppose I could tell the elves to turn down the central heating in the workshop. But they complain they can't make the toys if their fingers get too cold.
What is your biggest environmental sin?
Flying round the whole world delivering presents to children once a year. Those reindeer create a lot of methane.
Global warming - man or nature?
I'd have to say man-made. There are so many planes in the sky now that it's a wonder no one's spotted me.
