Yes, a carbon tax would go a long way, but I think a broader view is to look for ways to use taxes to shift externalities back onto the organizations that created the problem. For example, data centers (a popular demon). The two main externalities are water consumption and power consumption. The tariffs for providing those services to a data center should be high enough to compensate the rest of the community for the impact the data center has on the community.

For example, tariffs could be used to subsidize non-data-center power users. Higher tariffs could also be used to fund community solar and community BESS, helping provide greater local grid resilience. For example, the tariffs should be high enough to subsidize everybody else so they don't have to pay more for their electric service, roughly speaking.

I would also advocate closing the on-prem generator loophole by classifying on-prem power generation services as belonging to or leased from local utilities, and setting the tariff for locally generated power to match the tariff they pay for drawing from the grid.
