Climate Emergency and Politicians?

I must admit to not having been overly impressed by UK politicians, even the ones who are advocating recognising that there is a climate emergency. It's commendable that they recognize that we have a problem but many of their musings seem to (over?) stress the benefits of actions in terms of potential jobs, increases in national wealth et cetera. It seems likely that any real action that is going to be sufficiently timely to stave off Planet Sauna will inevitably cause some widespread pain. This pain must be fairly shared or the chances of a programme being acted on are remote.
