Brussels effect

The Brussels effect is the process of European Union (EU) regulations spreading well beyond the EU's borders. Through the Brussels effect, regulated entities, especially corporations, end up complying with EU laws even outside the EU for a variety of reasons. The effect is named after the city of Brussels, the de facto capital of the European Union, used as a metonym for the European Union.

The combination of market size, market importance, relatively stringent standards and regulatory capacity of the European Union can have the effect that firms trading internationally find that it is not economically, legally or technically practical to maintain lower standards in non-EU markets. Non-EU companies exporting globally can find that it is beneficial to adopt standards set in Brussels uniformly throughout their business.

The term Brussels effect was coined in 2012 by professor Anu Bradford of Columbia Law School. Scholars could so far not empirically verify the limits of the Brussels effect in international law, especially World Trade Organization (WTO) law. Furthermore, for the Brussels effect to occur, it was shown that not all prerequisites identified by Bradford have to occur cumulatively. Research has indicated that the EU's regulatory power varies substantially depending on the context of the regulation involved.

Since its discovery, the Brussels effect has become a major point of reference in European policy discussions on the EU's global power. However, scholarship has also noted the one-directionality of the Brussels effect framework, as it typically excludes for example the attempts by foreign firms and states to influence EU legislation. Moreover, it has been noted that the impact of the rules instigated by the EU can evolve significantly over time, as they get for example challenged in courts.

The October 2000 $42 billion proposed acquisition of US-based Honeywell by US-based General Electric was blocked by the EU antitrust authorities on the grounds of risking a horizontal monopoly in jet engines. The merger could not proceed because, despite the American Department of Justice having already approved the merger between these two US-based entities, it was not legally possible to let the acquisition proceed in one important market, but not in another.

US-based multinational Dow Chemical announced in 2006 it would comply with the EU's Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) regulation for the production and use of chemical substances across its global operation.

In 2012 the EU included aviation into its existing Emission Trading Scheme. This means that any airline, regardless of their country of origin, has to purchase emissions permits for any flights within the European Economic Area. The cost of complying with EU aviation emission regulation puts pressure on manufacturers to design airplanes with improved efficiency and reduced emissions. As major airlines would not likely purchase airplanes specifically to fly outside the EEA, the EU's stricter aviation standards have an impact on global airplane fleets, regardless of the jurisdiction of the airline.

With the introduction of the Data Protection Directive in 1995 the EU had opted for a strict top-down approach to data privacy. Its successor, the EU's General Data Protection Regulation (GDPR), was adopted on 14 April 2016 and had a global effect. In 2017, during negotiations for a new Japan-EU trade deal, Japan set up an independent agency to handle privacy complaints to conform with the EU's new privacy regulation.
