My position on shale gas is well known. But I recently came across a very interesting document which may be of interest to both sides of the debate. It’s a new concept to me: an “Argument Map”. It aims to set out the main arguments, by category, on each side of the question. It merely says what they are, with no attempt to evaluate the validity or to estimate the relative importance of each argument.
I think that both those in favour of shale gas, and those against, will find it of interest, so I offer it to you for what it is worth. The scheme was commissioned by TNO, a Dutch research NGO.
