The Malta Environment and Resources Authority (ERA) has approved preliminary works for the controversial Six Senses Comino development, sparking fierce opposition from environmental organizations who argue that private commercial interests are overriding constitutional environmental protections on an island designated as one of Europe's most ecologically sensitive sites.
Why This Matters
• Hundreds of trees are being removed from a Natura 2000 protected site, including mature Aleppo pines and cypress species.
• The €170 million resort project includes 44 swimming pools on an island with no natural freshwater supply.
• A court annulled the original Planning Authority permit after its April 2025 approval, ordering reassessment—but tree removal continues under separate ERA authorization.
• Environmental groups warn this sets a dangerous precedent for further commercialization of Malta's protected islands.
The Constitutional Tension at Comino's Heart
Malta's Constitution enshrines two competing principles that now collide dramatically on the 3.5 square kilometer island between Malta and Gozo. Article 9 mandates the State to "protect and conserve the environment... for the benefit of present and future generations," while Article 18 encourages private economic enterprise. The problem, according to legal experts and environmental advocates, is that these Chapter 2 principles guide governance but carry no direct enforcement mechanism in court.
This legal ambiguity has allowed HV Hospitality, a subsidiary of the Hili Group, to advance its Six Senses Comino resort despite the island's multiple layers of protection: it is a Special Area of Conservation under EU Habitats Directive, a Special Protection Area under the Birds Directive, and holds national designations as an Area of Ecological Importance, Site of Scientific Importance, and Nature Reserve.
The Gozo and Comino Local Plan explicitly establishes a presumption against urban-related development, yet the Planning Authority approved the project in April 2025. When a court subsequently annulled that permit, citing irregularities and insufficient scrutiny of planning policies, the victory proved hollow—ERA's separate authorization for preliminary works, including mass tree removal, remained valid.
What This Means for Comino's Ecosystem
The Malta Chamber of Scientists, together with Żminijietna, Moviment Graffitti, BirdLife Malta, and student coalitions, have united in opposition, citing a fundamental flaw in the approval process: cumulative impact is being ignored. Authorities assess individual project elements—tree removal here, building footprint there—without evaluating the combined strain on an ecosystem already buckling under mass tourism.
Comino receives thousands of daily visitors during summer months, concentrated at the Blue Lagoon and Santa Marija Bay. The island has no natural freshwater capacity and depends entirely on imported resources. The proposed development would add a 140-bed hotel, 16 serviced bungalows, and 44 swimming pools to this equation, dramatically escalating demands for water, energy, and waste management on an island barely 3 kilometers long.
The developer, in partnership with the Six Senses luxury brand, has emphasized sustainability credentials: the design by Belvedere Architecture targets Zero-Net-Carbon status and LEED certification, promises autonomous fresh and wastewater systems, and commits to planting over 55,000 indigenous plants as part of a reforestation initiative. The project also pledges to restore more than 8,200 square meters of developed land to natural garigue habitat and eliminate untreated sewage discharge into surrounding waters.
Critics dismiss these promises as insufficient mitigation. The Malta Chamber of Scientists points out that replacing mature trees—which provide shade, stabilize soil, manage water runoff, and offer wildlife habitat—with saplings that will take decades to mature represents a net ecological loss. The chamber has called for a "holistic sustainability assessment" that addresses fundamental questions: Where will water for 44 pools originate? How will waste management cope with increased load? What happens to migratory bird routes disrupted by light pollution?
The Precedent Problem
Environmental advocates fear the Comino project resurrects a historical pattern of exploitation. The island was once heavily wooded, but centuries of overuse for agriculture and quarrying left it largely barren. Twentieth-century tourism development concentrated at San Niklaw Bay and Santa Marija Bay, where the existing Comino Hotel stands. Approval of an intensified development, opponents argue, signals that commercial interests can override even the strictest environmental designations if the economic case is compelling enough.
Din l-Art Ħelwa and other heritage organizations note that the project increases total built floor area despite developer claims of "lower density." While guest numbers would drop from 284 to 240 under the revised plans, the physical footprint of structures, pools, and supporting infrastructure expands into areas currently vegetated or designated as Rural Conservation Area.
The removal of trees began even as the legal challenge to the main permit proceeded through tribunals. ERA authorized the uprooting of hundreds of specimens, including non-endemic oleanders and Mexican fan palms, as well as protected species. The developer is obligated to plant 540 indigenous saplings to compensate for 54 protected trees removed, and to replace any transplanted trees that fail to survive. Environmental groups call this formulaic replacement inadequate, arguing that ecological function cannot be replicated on a spreadsheet.
Public Access and Accountability Concerns
The development plan restricts public access to the hotel perimeter and immediate shoreline for "health and safety reasons," a provision that alarms local councils and residents who view Comino as a shared national asset. The Għajnsielem local council on Gozo, which has administrative oversight, joined environmental NGOs in opposing the permit, citing the absence of a comprehensive carrying capacity study for the island.
Trust in regulatory authorities has eroded significantly. The Environment and Planning Review Tribunal (EPRT) initially upheld the Planning Authority's permit, only to have a court find irregularities in that confirmation and order reassessment. The perception among environmental organizations is that authorities are consistently yielding to commercial pressure, sacrificing long-term ecological integrity for short-term economic gains.
There is also frustration over transparency. Details about water sourcing, energy generation, and waste logistics remain vague in publicly available project documentation. The developer's sustainability commitments—passive building design, renewable energy, autonomous water systems—are welcomed in principle but lack independent verification mechanisms or enforceable performance benchmarks.
Alternative Paths for Sustainable Tourism
The controversy has reignited debate about Comino's tourism model. Overcrowding at the Blue Lagoon has become emblematic of Malta's broader struggle to balance economic benefits from tourism with environmental preservation. During peak summer months, trampling of vegetation, litter accumulation, and disturbance to nesting seabirds are routine problems.
Several sustainable tourism alternatives have been proposed:
Visitor quotas and pre-booking systems would cap daily arrivals, especially at the Blue Lagoon, distributing pressure across less-visited sites. An eco-tax for day visitors could fund conservation programs and offset tour operator losses from reduced capacity. The concept was piloted with an online registration system, though it faced suspension amid operational challenges.
Habitat restoration programs focusing on endemic garigue species, combined with strict zero-discharge policies for sewage and waste, could reverse decades of degradation. Enhanced educational signage, onsite monitors, and a visitor interpretation center would raise awareness of Comino's protected status—a fact many tourists remain unaware of.
The Malta Tourism Authority and environmental agencies proposed a strategic plan for the Blue Lagoon scheduled for implementation in 2026, including restricted ferry operations, upgraded sanitation facilities, and reorganized food outlets designed to minimize environmental footprint. However, progress on these measures has been slow, and environmental groups question whether authorities possess the political will to enforce meaningful restrictions.
What Happens Next
The legal status of the Six Senses Comino project remains uncertain. The court's annulment of the original Planning Authority permit has triggered a reassessment process by the Environment and Planning Review Tribunal, with no clear timeline for resolution. ERA's approval for preliminary works stands, meaning tree removal and site preparation can continue even as the core permit undergoes scrutiny.
Environmental organizations have vowed to escalate their legal challenges if necessary, including potential appeals to European Commission oversight bodies regarding Malta's compliance with EU Habitats and Birds Directives. The commission has previously issued warnings to Malta over failures to adequately protect Natura 2000 sites.
For residents and visitors alike, Comino represents a test case for Malta's environmental priorities. The island's fate will signal whether the nation's constitutional commitment to conservation for "present and future generations" carries substantive weight, or whether economic enterprise will consistently prevail when the two principles collide.
The developer maintains that the project represents a responsible upgrade to aging infrastructure, replacing an outdated hotel with a genuinely sustainable luxury model that will reduce environmental impact while supporting employment. The Malta Hotels and Restaurants Association has backed the development, emphasizing the tourism sector's economic importance to the Maltese islands.
Opponents counter that sustainability claims cannot erase the fundamental incompatibility of large-scale resort development with a protected nature reserve. As one scientist put it during public consultations: "You cannot build your way to conservation."
The debate over Comino's future continues, with the island's fragile ecosystems caught between competing visions of Malta's development trajectory.
