The Commission's Competition Directorate-General is responsible for promoting and regulating competition in the European Union. Their main role is to ensure a level playing field in the market and prevent anti-competitive practices, such as cartels, abuses of dominant market position, and state aid.

To encourage competition, the Directorate-General conducts investigations and enforces competition laws. They investigate cases of anti-competitive behavior, such as price-fixing agreements or market sharing arrangements, and take appropriate action to prevent such practices.

The Directorate-General also reviews mergers and acquisitions to ensure they do not reduce competition in the market. They assess the potential impact of mergers on competition and may require remedies or block the transaction if it would harm competition.

In addition to enforcement activities, the Competition Directorate-General also promotes competition through policy development and advocacy. They provide guidance to businesses on compliance with competition laws and work to raise awareness about the benefits of competition in the market.

Overall, the Directorate-General plays a crucial role in creating a competitive and fair business environment in the EU, protecting the interests of consumers and promoting economic growth.

If you would like more detailed information, I recommend visiting the official website of the Commission's Competition Directorate-General or referring to the sources mentioned earlier.
