In this long format article I will explore why a knee-jerk response to the climate emergency can lead to well intentioned but counterproductive consequences. I have heard it said that we are living in a time where political reality is approximating scientific reality – at last policymakers are beginning to grasp what science has been saying for many years. This article explores another critical dimension, which I will call engineering reality, where I believe that much of the hard work and tough choices around climate change will be focused. The broader themes in this article are absolutely central to our success or failure and are offered not as a criticism of one specific response, but as a broader lesson to all those who can influence our responses to climate change.

The climate emergency is real and requires a rapid and effective response. Our success in delivering fast decarbonisation of our economy depends on myriad decisions taken in every sector based on our knowledge of the technologies, skills and finance available. These decisions are intricate and complex, not helped by a large number of uncertainties about the future, inconsistent data and conflicting visions of how to achieve Net Zero emissions.The climate emergency is real and requires a rapid and effective response.

Those of us who have been in the business of sustainability for a long time[1] crave a John F. Kennedy moment: “we will put a man on the moon by the end of the decade”. We fancy the notion of a mobilisation of all resources available to limit climate change, to adopt a state of war where combating climate change become the overwhelming priority in everything we do. We can’t wait to see the many barriers we have faced in the past come tumbling down.
