The economy changes.

Sometimes it evolves slowly.

Sometimes it changes fast.

But more often there is a slow evolution up to a tipping point and, then, BOOM.

This can be in a niche area, such as the almost complete replacement of virgin glycerol by biodiesel byproducts. Or it can be on a massive scale, such as the high street meltdown caused by internet shopping and the associated shift to digital entertainment – MP3s, eBooks, movies on demand etc.

But with the big buyers – the big retailers and the public sector – shifting from low impact suppliers to high impact suppliers, some companies are going to see huge opportunities and others existential threats.

So are you ready to bloom in the new green economy, or are you just going to fade away with the old?
