Is ‘net zero’ a moral pursuit?

The party conference season kicked off with claims and counter claims about the viability of Nigel Farage’s proposals for government. One issue that unites Reform and Kemi Badenoch’s Conservatives is scrapping the 2050 net zero target, echoing US President Donald Trump's pledge to "drill, baby, drill" and embark on new oil and gas exploration.

This is a turbulent time in international politics. The prospect of achieving a global consensus on climate action seems a forlorn hope. What’s more, critics of the UK net zero target argue that the costs will cause a decline in living standards for little overall benefit.

Forget economic arguments: what is the moral thing to do in the face of a warming planet, rising sea levels, more extreme weather, food and water insecurity, and human displacement?

Readers of Immanuel Kant might be tempted to invoke his ‘categorical imperative’, a moral rule that says you should act in a way that you would want to apply to everyone, regardless of your personal desires or the potential outcomes of your actions. In climate terms, it means pursuing net zero as a moral good in itself. Utilitarian ethics, however, says that the right action is the one producing the most happiness and the least unhappiness for the greatest number of people. Therefore, it could be argued that the detrimental consequences of pursuing net zero in the UK, combined with its questionable global benefit, make it immoral.
