We can’t ignore the fact that we exist in a global market economy. So where does the global market economy fit into the transition? What part does it need to play to make the transition happen?

We are a planet filled with consumers.

We as consumers must change our behaviour.

Behaviour change must be incentivised. Otherwise nothing will change.

We need in other words a reward system that values contributions to the commons and is packaged up for the markets to invest in it.

One single metric to replace GDP – that ordinary people can understand and produce for themselves – is the missing link.

Establishing such a metric isn’t easy. But as the kilogram and kilometre have proved in days of old, it’s not impossible.

It just needs agreement.
