Europe backs critical mineral mines in water-stressed regions despite drought concerns

The European Union’s push to secure critical minerals is colliding with a constraint that cannot be negotiated away: water.

A Guardian analysis based on Watershed Investigations says more than half of the EU’s 33 planned new or expanded strategic mine projects are in areas that have been drying over the past two decades. Nearly half are in places that experienced drought in the past three months, and about a quarter are in regions already classified as water-stressed.

The reporting lands as Brussels prepares changes to water rules that critics say could make it easier to approve mining and other projects tied to Europe’s supply-chain strategy. Supporters say the aim is faster permitting and clearer rules for projects the bloc considers strategically important.

A fast-track built around critical minerals

The issue sits inside a wider European strategy to reduce dependence on imported raw materials. The EU adopted the Critical Raw Materials Act in 2024, creating a faster permitting path for designated strategic projects inside the bloc and support for access to finance for projects outside it.

That law was designed to help Europe secure minerals used in electric vehicles, renewable energy technologies, AI infrastructure and defence systems. It was also meant to improve supply-chain resilience after years of concern about import dependence and geopolitical risk.

But the same policy is now pushing more mining activity into places where water is already under strain. Mining is water-intensive, and its demands do not stop at the mine gate: ore processing, dust suppression, waste management and dewatering all require large volumes of water.

Where the projects are landing

The Guardian says the concentration is especially sharp in southern Europe. Six of the strategic mines are planned in highly water-stressed parts of Spain, with others in Portugal and Greece.

Those countries are repeatedly identified in the reporting as among the EU’s most water-scarce. That makes mine siting more than a planning issue. It becomes a question of whether the bloc is concentrating industrial development in basins that are already stretched by drought, rising demand and long-term drying.

The analysis suggests that the locations are not a minor edge case. More than half of the strategic projects are in places that have been drying over two decades, which points to a structural mismatch between the minerals push and water availability.

Nearly half of the projects are also in areas that experienced drought in the past three months. That does not by itself determine whether any individual project should go ahead, but it underlines the pressure on local hydrology and the sensitivity of permits in those regions.

Brussels, water law and permitting

The reporting says the European Commission is preparing to revise the Water Framework Directive in an effort to remove permitting bottlenecks and improve access to critical raw materials.

The Water Framework Directive is the EU’s main water-protection law for rivers, groundwater and wetlands. Any change to how it is applied, interpreted or amended would have consequences far beyond mining, because it shapes how the bloc balances industrial development with water quality and ecosystem protection.

That is why the proposal matters politically. If Brussels narrows or streamlines the water regime, it could speed strategic projects. If it preserves the current approach, some supporters of the minerals push may see that as another obstacle to domestic supply-chain security.

The Commission says the strategic projects were assessed by independent experts and must still comply with EU environmental law. That is central to its defense of the process: that speed does not mean exemption.

Industry and environmental reaction

Euromines, the industry group, says it wants legal clarity and predictability alongside environmental safeguards. It rejects the idea that the changes amount to a license to pollute.

Environmental groups see the issue differently. The European Environmental Bureau and other campaigners argue that weakening water protections would undermine Europe’s water resilience and shift costs onto taxpayers, farmers and local communities.

Their concern is not just about pollution in the abstract. It is about the cumulative effect of pushing water-intensive projects into already stressed basins, where competition for water can quickly become a conflict between mines, agriculture, households and ecosystems.

The clash exposes a fault line inside Europe’s green and industrial transition. The same policy package that is meant to support the shift to cleaner technologies also risks intensifying pressure on the natural systems those technologies depend on.

Why the timing matters

The policy backdrop is older, but the reporting gives the issue new urgency. The Critical Raw Materials Act entered into force in May 2024, and the Commission later designated a first wave of strategic projects in March 2025.

The Guardian and Watershed Investigations analysis published on June 20, 2026, adds a location-specific warning to that framework: many of the projects meant to secure Europe’s mineral future are being placed in some of its driest and most contested watersheds.

That creates a new political test for Brussels. A fast-track regime can reduce delays, but it cannot make water appear where it is scarce. Nor can it remove the fact that local opposition, permitting disputes and legal challenges are likely to intensify where mines overlap with drought risk.

What comes next

The immediate question is whether the European Commission formally publishes a proposal to amend the Water Framework Directive, and if so, what exactly it would change.

Another open question is how far member states and the European Parliament will go in resisting any move they see as weakening environmental review. The reporting suggests that the politics could become especially sharp in Spain, where several projects are already in highly water-stressed areas.

There is also the question of legal challenge. Strategic-project designations can speed approvals, but they do not end controversy. If local communities or environmental groups believe the rules have been loosened too far, litigation is a likely next step.

For now, the dispute captures a central trade-off in Europe’s critical-minerals strategy: whether the bloc can accelerate strategic mining without deepening water stress in the places that will host it.
