The European Union is one of the world’s leading economic powers in the fight against greenhouse gas emissions. In 2020, greenhouse gas emissions in the EU were 31% lower than in 1990, exceeding the EU’s target of reducing emissions by 20% by 2020. In accordance with international agreements such as the Kyoto Protocol, the EU has adopted numerous climate policies, including the establishment of the EU Emissions Trading System. In 2019, the European Commission presented the European Green Deal. Since then, numerous measures have been adopted to achieve the EU’s target of reducing emissions by 55% by 2030 and gradually phasing out fossil fuels from the EU economy by 2050, in line with the Paris Agreement.
