In recent years, several countries have taken measures to reduce carbon emissions, including instituting environmental regulations, emissions trading systems (ETSs), and carbon taxes. In 1990, Finland was the world’s first country to introduce a carbon tax. Since then, 23 European countries have implemented carbon taxes, ranging from less than €1 per metric ton of carbon emissions in Ukraine to more than €100 in Sweden, Liechtenstein, and Switzerland.
