Sustainable Tourism in Mallorca is under scrutiny due to the increasing numbers of tourists placing greater strain on local resources including energy and water; and acute problems over waste and pollution.

The primary issue in Majorca (Mallorca) is "overtourism," a state where the volume of visitors is perceived as unsustainable for the local environment and community. In 2025 and 2026, the island has seen record-breaking visitor numbers, leading to intense housing pressures as long-term rentals are converted into more lucrative short-term holiday lets, effectively pricing out local residents. Environmental strain is also a major concern; the surge in population during peak summer months has severely affected water quality at several beaches and depleted natural resources. This saturation has sparked significant "anti-tourism" protests across the island, with residents calling for a more balanced model that prioritizes the quality of life for locals over the sheer quantity of visitors. The local government has responded with measures like increased tourist taxes and stricter regulations on cruise ship arrivals, but the tension between the island's economic dependence on tourism and the social cost of mass crowds remains a heated and unresolved conflict.
