> The actual cost of gas
The actual cost has to price in the impact of using it.
For example, it's cheaper for UK water companies to pump sewage into rivers and onto beaches:

But maybe it's a nice idea to force them to deal with sewage properly so you don't have to live in rivers of shit.

Is there real evidence the collected tax revenue is actually offsetting carbon emissions?
There's a lot of fraud in carbon credit systems - where often the sole benefit is feeling and/or looking good.
Is this self-imposed tax actually having a real result - or is it just artificially increasing the price of energy? If the latter, then it's not really fair to claim it's the actual cost.
The "actual cost" is a loaded term and probably cannot be known without putting reasonable bounds on it.
Nonetheless, two thoughts come to mind:
1) we don't know the "actual cost" of offshore wind
2) we may not be able to afford even the "market cost" of offshore wind without the natgas tax subsidy
