Companies use fossil fuels because they have no choice, either because of chemistry or because of the doctrine of shareholder primacy, or because they lack access to credit.

There are no alternatives to carbon-intensive inputs in the offing for many industries. For all of them, efficiency measures require capital investment. Borrowing to install efficiency measures reduces next-quarter returns to stockholders. Companies with low profits have a hard time borrowing.

Yes, it may be a pain point, but it's also a coordination problem (or three).

The cases where efficiency provides a clear benefit? Few and small, on the global scale.

I don't agree with that. Any opportunity to make a 10% reduction in carbon emission that also saves you money should be pursued, and there should be a lot of them out there.
