My thoughts on it are that it's not random or bad planning or desperation at all, but a carefully considered and worryingly quite good plan...
I think they know it's looking unlikely they're going to the win the next election. They've latched onto this as an issue to force the hand of Labour to take a stance against them that I think will enable them to argue the case against any policies that they can paint as unfair or causing problems for the 'average person/hard working family/etc.' which I think will be a strong line of attack and sadly quite popular, and we can see that already with some issues. Labour are already running scared on some issues, look at their refusal to cancel Rosebank oil for example.
I do think people want changes around the environment and climate (the polling says so regularly) but what changes and how much people want their daily lives to be impacted is another whole area that's much less clear.
So, I think they're using this to help them win the next election, but more realistically will likely lose that but are hoping they can then spend 4 years painting Labour as eco-zealots against the 'normal folks' and come back in the election of 2028 elected partly on that ticket.
It does worry me.
