The problem is not the air condition or the electricity needed to run the air conditioner.
The problem is the electricity was generated by burning a fossil fuel and that causes massive amounts of CO2 pollution.
So the solution is quite simple.
Just tax, and tax hard any electricity producer that is creating CO2 pollution.
What will happen is for a short time Joe's electricity bill will go up and he will put his air con on low.
But in the longer term market forces will quickly find ways to make electricity without producing CO2 just so that they can sell cheaper electricity to Joe and have him once again cranking up his air con to full.
Right now there is no real cost to creating CO2 pollution so of course there is no incentive to stop producing CO2.
