Abstract
CO2 emissions from buildings and traffic are at the heart of the environmental policy debate. Proposals include no new combustion vehicles from 2035, at least 65 % of heating from renewable energy sources, extended certificate trading to emissions from buildings and traffic, speed limits on freeways, vehicle tax that is aligned more closely with CO2 emissions and the end of the company car privilege. How suitable are these instruments? If the most important assessment criterion for these measures – static efficiency – is applied, the result is a demand for comprehensive certificate trading that is strictly oriented towards the climate policy goals of the Paris Climate Agreement in terms of its quantity restrictions. The EU and Germany are on the right track here. The regulatory and other pricing measures would then be obsolete.
