MEP Emma Fourreau (The Left) has called on the European Commission to withdraw financial support for the Seine-Nord Europe canal, citing severe environmental damage, massive cost overruns, and the project's heavy reliance on EU funds. In a parliamentary question submitted on 8 July 2026, Fourreau argued that the canal's construction increases land take and reduces biodiversity, while its viability is undermined by delays and escalating expenses. She pointed to a recent European Court of Auditors report estimating total costs at EUR 5.1 billion, and a French Court of Auditors assessment putting the figure between EUR 8.38 billion and EUR 10.53 billion before tax. Noting that EU funding covers around 40% of eligible expenditure and that project officials have described Europe as the project's 'life insurance', Fourreau asked whether the Commission intends to stop providing financial support.
The question reflects a growing cleavage between environmental protection and large-scale infrastructure development, with Fourreau prioritising ecological concerns and fiscal responsibility over the canal's potential economic benefits. The project, which aims to connect the Seine basin to the Scheldt and Rhine networks, is expected to boost freight transport and reduce road congestion, but critics argue the environmental and financial costs outweigh these gains. The Commission typically has six weeks to respond, and its answer will signal whether it continues to back the project or shifts its stance in light of the audits. Stakeholders most impacted include EU taxpayers, who bear a significant share of the costs; local communities and ecosystems affected by construction; the French and Belgian transport and logistics sectors, which stand to benefit from improved waterways; and EU regulatory bodies, which must balance cohesion funding rules with environmental and budgetary constraints.
