It isn't often that we feel the weight of history on our shoulders, or rather the weight of the future. I welcome the Welsh Government's declaration of a climate emergency, but as the point has been made by Members across the Chamber, it must be backed up with action. The Oxford English Dictionary defines an emergency as 'a serious situation requiring immediate action'. It is defined by the fact that it necessitates doing something in response, so I'm sure the Welsh Government will appreciate the need to make the right call on projects like the M4 relief road. You cannot declare a climate emergency and continue to countenance the possibility of building that black route; it would be irrational. We are living in a hugely significant time. Yes, I'll take an intervention.
