Fourth Phase of EU Emissions Trading System Launches with Stricter Regulations
The fourth phase of the EU Emissions Trading System (ETS) commenced, aiming to reduce CO2 emissions by 62% by 2030. The initiative impacts industries across Europe, pushing firms to adapt operations or risk increased costs and competition from regions with lower standards.

The fourth phase of the EU Emissions Trading System, covering the period from 2021 to 2030, has initiated stricter regulations to reduce CO2 emissions by 62% from 2005 levels. As the total number of emissions certificates will decrease annually and the linear reduction factor has been raised to approximately 4% per year, companies must either buy emissions rights or innovate to lower emissions.
The system now includes shipping and buildings, with a separate mechanism, ETS2, planned for implementation in 2027. The introduction of a Carbon Border Adjustment Mechanism aims to offset competitive disadvantages faced by EU producers. This regulatory framework may lead to increased operational costs for businesses, potentially driving some to relocate to countries with less stringent emissions standards, impacting overall emissions levels.
