The burden of coronavirus has been exacerbated and amplified by wider, deep-seated social, economic and health concerns. The right response is therefore not to duck or defer action on these longer-term challenges even as we continue to respond to immediate pressures. It is to confront them head on. One of the most significant is the climate emergency, which is also a health emergency. It is for this reason that the UK is committing to tackle climate change by reducing its emissions to ‘net zero.’ Other nations, including the U.S., are pursuing similar obligations to society.
