Politics is about moral choices. If you chose to do evil then admit it. Don’t try and hide behind meaningless distinctions in degree.
Stare them in the eye, those who will suffer, lose their homes or even their lives and tell them why you chose to harm rather than help them.

Bit surprised how little government made of the launch of the Warm Homes Loan Scheme today. Ultra low interest loans to help people cut energy bills by over £500 and improve their homes, which are also a key plank of Labour’s climate agenda. Bit bizarre not to give it the full fanfare.

I talk a lot about major transport investment, but one of the biggest bangs for the buck policy-wise would be a full pavement parking ban and more rigid enforcement of traffic rules.
Enforcement is so lax that this stuff is just completely normalised now, and it's unacceptable.

Part of the reason this sort of baffles people is that we still don't widely understand just how intensely silly it is to get energy from old dead compressed plants
Made this a few years ago but it's the same today: ~2/3rds of climate impacts relate to energy that was never 'used'
