Can climate change be declared a health emergency?

Are politicians already preparing to declare climate change a health emergency, so they can order personal carbon allowances that would limit travel by automobile or airplane and require tracking devices to enforce compliance?
Climate change is only one of many policy fields where the public health excuse could be used for government control of private decisions. COVID-19 lockdowns have prepared people for personal carbon allowances and restrictions on individual freedoms have prepared us to accept the tracking and limitations to achieve a safer climate.

Carbon emissions are embedded into nearly everything in our economy. Can you imagine what sort of things await us if politicians can declare climate change an emergency? I do not even want to think about it!
