Celebrity supporter - Alistair McGowan

Green Office Week supporter Alistair McGowan, the impressionist, actor and environmental campaigner, said: "If, like me, you spend most of your waking hours at work, I'd encourage you to take part in Green Office Week.

"It's not about being downhearted regarding climate change - it's a prompt to think and act just a little bit smarter.

"Green Office Week makes the point in a clever interactive way that we can all do simple, practical things to make a positive difference to our environment.

"By getting involved and embracing the various tips and ideas in the campaign and on the website, we can all change our behaviour for the better and, in our cuts-driven world, save a lot of money!"

Alistair McGown is the patron of the urban tree-planting charity Trees for Cities.
