What is loneliness and how can you manage it?
Carbon taxes work by directly setting a price on carbon by pricing each ton of GHG emitted or – more commonly – on the carbon content of fossil fuels. Essentially, the result is the same – these measures will capture the external cost associated with carbon emissions (e.g. addressing environmental damage) and shift the burden of these costs on to those who are responsible for them.
