Expansion Plans Face Environmental Criticism
On Sunday 20 September 2026, Carla Vega, a representative of the far-left CUP (Candidatura d'Unitat Popular) party, publicly dismissed the Spanish government and Generalitat de Catalunya's joint approval of expansion plans for Josep Tarradellas Barcelona-El Prat Airport as fundamentally contradictory. Vega labelled the ambition to make the airport both larger and the most sustainable in Europe an "oxymoron", challenging the environmental credibility of the project. The expansion, backed by Spain's Ministry of Transport and Sustainable Mobility and the regional Catalan government, was officially greenlit by Aena, the state-owned airport operator, earlier this month.
Aena's Sustainability Claims Under Scrutiny
Aena maintains that the expansion will incorporate advanced environmental safeguards, including noise reduction measures, increased use of renewable energy, and improved public transport links to cut road traffic. According to Aena's official sustainability page, the airport aims to achieve climate neutrality by 2050 and has already reduced CO₂ emissions by 47% since 2010. The agency also highlights its biodiversity initiatives, waste recycling rates above 70%, and ongoing investments in electric ground support equipment.
We cannot claim to lead in sustainability while increasing flight capacity and infrastructure at an airport already straining local communities and ecosystems.
, Carla Vega, CUP representative Despite these measures, critics like Vega argue that expanding physical infrastructure and increasing passenger capacity, potentially to over 70 million annually, are incompatible with genuine ecological responsibility. Local environmental groups have echoed her concerns, warning of increased noise pollution, air quality deterioration, and pressure on water resources in the Baix Llobregat area.
Political and Public Debate Intensifies
The airport expansion is part of a broader national strategy to position Barcelona as a major European aviation hub. Supporters, including regional business leaders and parts of the coalition government, argue it will boost tourism, create jobs, and improve connectivity. Opponents, however, demand a shift toward high-speed rail and regional decentralisation of air traffic, citing precedents in other European cities that have capped or reduced airport capacity for climate reasons. Public consultation on the environmental impact assessment is expected to open in early 2027, giving residents and organisations a formal channel to voice objections.
