It’s that head-scratching time of year again – when I ask you for a pithy one-liner for my ‘Green Business Pearls of Wisdom’ series of Xmas publications.

So, have you had a profound thought, a flash of blinding light, or a brutal learning experience in the field of sustainability, environmentalism and/or corporate social responsibility in the last 12 months?

If so, boil it down to 140 characters and get it immortalised in pixels for the 2014 edition of Pearls of Wisdom – the sixth in the series. Originality scores well, as do thoughts that run contrary to conventional green wisdom.

Send them to me here.

Over to you!
