If you read his comments closely, he was specifically talking about investment bankers. He talked about how it was hard to train junior bankers on deal making if not face-to-face. I think he used the term "apprenticeship". Even in the era of unlimited voice calls, emails, and video calls, as I understand, most M&A and IPO deals are still done face-to-face.

For the investment bank, many of the employees work in New York City and use a train (or bus) to commute. That is pretty low carbon intensity.

The same "apprenticeship" also applies to tech companies.

The claim is usually that people are more productive in the office. Assuming that's true, then what's actually more expensive: having existing employees commute, or employing, say, 10% more people? Even if you only care about carbon costs, what are the carbon costs of raising, educating, training, and giving healthcare and everything else to 10% more people?

Yeah.

It’s totally fine to ask everyone to stop eating meat, but millions of Americans running their cars to/from the office everyday? Not a peep.

Our politicians and business class are wholly unserious about this as they were about COVID-19.
