A cross-party group of 250 national and local politicians published an open letter on Sunday, 1 March 2026 calling for the ‘immediate abandonment’ of Aéroports de Paris’ (ADP) plan to extend and optimise capacity at Paris-Charles-de-Gaulle (CDG). The €6 billion programme—part of ADP’s 2027-2034 regulatory contract—aims to lift annual throughput from 76 million passengers to 90 million without building a fourth runway.
Signatories from Seine-Saint-Denis, Val-d’Oise and other départements argue the project represents a “historic contradiction” with France’s climate commitments. They warn of 34,000 additional aircraft movements and intensified noise pollution for millions of residents under flight paths. Environmental NGOs have joined the campaign, citing Transport & Environment modelling that shows CDG emissions could rise in absolute terms despite promises of sustainable-aviation-fuel deployment.
ADP counters that the plan relies on satellite extensions to Terminals 2E and 3, extra remote stands and upgraded baggage and border-control systems to smooth passenger flows. The operator pledges a 23 % cut in greenhouse-gas emissions by 2035 and says capacity growth is essential to safeguard CDG’s hub status for Air France-KLM and the 90,000 direct jobs on site.

For international travellers who may be affected by future capacity constraints—or simply want to streamline their journey through France—VisaHQ offers a quick, digital pathway to secure the necessary visas and travel documents. Its online platform provides step-by-step guidance, real-time status updates and expert support for France and more than 200 other destinations, helping passengers avoid administrative pitfalls even as airport infrastructure evolves (https://www.visahq.com/france/).
For globally mobile companies, the political row matters because it could delay investment decisions around CDG’s proposed business-aviation facilities, new hotel space and improved Schengen/non-Schengen transfer corridors. Any postponement would prolong today’s bottlenecks at immigration during peak banks and weaken Paris’ competitiveness against Amsterdam Schiphol and Frankfurt.
The government must now decide whether to approve ADP’s economic-regulation contract before summer. If the coalition of mayors and MPs succeeds in forcing a public enquiry or injunction, CDG users could face years of capacity constraints just as the 2027 Rugby World Cup and 2028 Olympic legacy traffic ramp up.
