> carbon tax? No you want an emissions trading scheme instead of a carbon tax. Only this way the government can actually enforce strict upper limits on CO2 emissions („cap“) and allow economic subjects to sell their emission rights for profit („trade“). Compared to a carbon tax „cap and trade“ makes the regulation of carbon emissions more efficient both for all market participants and the government.
