Europe’s Energy Diplomacy Tested as Qatar Threatens LNG Cut Over EU Sustainability Rules

Europe’s ambitious push for sustainability through the new Corporate Sustainability Due Diligence Directive (CSDDD) sparked geopolitical tension last week, as Qatar reportedly threatened to reduce liquefied natural gas (LNG) supplies to the EU. According to a letter revealed by Reuters, QatarEnergy’s CEO Saad Sherida Al Kaabi warned Belgium that the bloc’s new regulatory framework could jeopardize ongoing energy cooperation. The CSDDD, recently passed by the European Commission, mandates that large EU-based companies, including foreign entities with major EU operations — must identify and mitigate human rights and environmental violations throughout their global supply chains. This directive is seen as a cornerstone of the EU’s Green Deal and ethical business transformation agenda. Qatar, one of the world’s top three LNG exporters, viewed the legislation as an overreach and a potential threat to its energy trade. The letter, dated 21 May and addressed to the Belgian government, expressed serious concern over the directive’s implications for existing energy contracts and Qatar’s operational sovereignty. Al Kaabi's warning signaled a possible recalibration of Qatar's supply commitments to the European market. This development came at a time when Europe is working to diversify its energy sources post-Russia, with Qatar emerging as a key supplier. The diplomatic tension underscores the growing friction between energy security and sustainability enforcement. With winter approaching and gas reserves under constant scrutiny, Brussels now faces the challenge of balancing environmental values with strategic energy relationships.
