I met the news that a national group has been set up to oppose wind turbines with an incredulous “why?!” Do they not understand the challenge of climate change? Do they not see the consistently high cost of fossil fuels? Do they not want energy security? Do they not want clean air? Why waste all this time and money holding back progress?

But then again, while I like to think I like change (new shiny gadget!), often I hate it. If a favourite cafe closes or even changes its menu, I get really disappointed, even though this is just part of life. Things change, things evolve, but we do like to cling to certainties.

I often say the biggest barrier to sustainability is just six inches wide – the space between our ears. When we get together, this barrier increases exponentially to get what I call institutional inertia and that can kill your sustainability programme. There’s always a reason to do nothing – it’ll cost money, too risky, we need more data, we have other priorities this year, we’ve already done one green project this year… I’ve heard them all!

To address this inertia takes guile and determination. Green jujitsu helps – don’t argue and battle, get people thinking and involved in the process instead. Ask them for help and solutions. Get teams involved in the challenge. And don’t give up.
