How do we get mobility that creates more value than it destroys?
Mobility is the potential for movement. That the road is clear if I want to drive. That there is a bus or other public transport running on schedule. That there are safe sidewalks and bike lanes.

Without making comment on this specific firm or tech, the idea that automated vehicles will be amazing and cheap and people will only want to rent them rather than buy them always struck me as a weak assumption. I think people will want to own them if the cost comes down.

Imagine showing a petrol engine to someone who had only known electric vehicles, and trying to convince them to switch to petrol. No-one would choose the dirty, noisy, less efficient, more expensive vehicle. This isn't 1910, hostage to gender insecurity. We can just choose the better tech.

WORKPLACE PARKING. Has anyone heard of an employer paying people a daily sum, which if you drove went towards your parking space and if you didn't drive went into your pocket? I'm sure I've heard of somewhere doing this, but cannot remember where I heard it

Mark Carney managed to trade a pipeline that will never get built for meaningful progress on industrial carbon pricing and electricity interties — both of which will get more wind and solar built.

👀 If the NYC pension boards adopt the @nyccomptroller.bsky.social recommendations and move BlackRock's $42B mandate to other asset managers, it could be one of the most consequential climate-related actions ever taken by a pension fund in the US or anywhere in the world.
Today I’m recommending that NYC’s pension fund boards drop BlackRock and 2 other (out of 49) public markets asset managers due to inadequate decarbonization plans.
