The correct way to solve the market failure of externalities is taxation, not social shaming.

This isn't directed at swift as much as at the wealthy in general. What you might call social shaming, many people simply call transparency. Or, if you're going to tax my SUV more I'd like to find out if it impacts your corporate jet proportionally.

There is a direct relationship between fuel usage and carbon dioxide. It's very simple to tax fairly.

Like carbon credits? Pretty sure that's been gamed ...

No, like consumption tax. Pretty sure that can't be gamed.

Is someone tracking your CO2 emissions when you drive or travel by commercial jet? There's no database I'm aware of where I can search for your name and see all your vehicular movement.
