I thank Caroline Lucas for bringing forward this debate and for many years of leadership, giving vision in this area and a lot of practical direction. The necessity for change, and the failures of the economic model that we currently operate, are all around us: in climate and nature breakdown, in inequality within and between nations of the world and between generations, in the depletion of resources and the hoarding of wealth, and in the mental ill health and lack of fulfilment that are beginning to engulf our populations.

Alyn Smith outlined some of the absurdities of GDP as our sole measurement, with all of the negative effects simply written off as “externalities”. It is very clear that a system that accounts for tobacco sales and bets placed by gambling addicts, but does not find any way to capture time spent raising children or the value of clean air, is no longer fit for purpose. We have known that for decades.

The impacts of consumption and growth-driven production on our planet do not need to be articulated in this room. I know that because this country and others like it consume, drill, burn and dump at a rate that would require numerous planets to sustain it. That, of course, causes negative impacts for the planet and its inhabitants.

It would be one thing to keep pursuing this model if it resulted in a healthy and happy population, but it does not. We know that income inequality in the UK is higher than it has been for decades, and probably the highest in Europe. It affects people at every single point on the economic distribution scale, as well as overall societal cohesion. In the absence of any serious mitigation policies, that will unfortunately only get worse.
