Is Tourism in the Canary Islands Sustainable When Almost All Tourists Arrive by Plane?
The Canary Islands, an archipelago off the northwest coast of Africa, have long been a major tourist destination, attracting visitors with their year-round warm climate, stunning landscapes, and vibrant cultural heritage. However, concerns about the sustainability of this tourism model are growing, especially given that the vast majority of visitors arrive by air travel. According to a recent study by the political party Drago Canarias, tourism numbers in the Canary Islands could reach 20 million in 2026, an increase of over two million from 2024. This raises pressing questions about environmental impact, resource management, and the long-term viability of the islands as a travel destination.
The Environmental Impact of Air Travel
One of the primary sustainability challenges for the Canary Islands’ tourism industry is the environmental impact of air travel. The aviation sector is one of the fastest-growing sources of greenhouse gas emissions, contributing significantly to climate change. The emissions from flights to and from the Canary Islands contribute to their carbon footprint, raising concerns about whether the region’s tourism-dependent economy can align with global sustainability goals.
Carbon Footprint of Flights to the Canary Islands
A single round-trip flight from a European city such as London or Berlin to the Canary Islands can generate between 500 and 1,500 kilograms of CO2 per passenger. With projected arrivals reaching 20 million in 2026, the total emissions from air travel alone could reach several million tons of CO2 annually, exacerbating global warming.
Limited Alternatives to Air Travel
Unlike many other tourist destinations, the Canary Islands are geographically isolated, making alternative transportation methods like trains or road travel impossible. Although ferries operate between mainland Spain and the islands, they remain an impractical choice for most tourists due to time constraints. This lack of viable alternatives makes the region heavily dependent on air travel, complicating efforts to transition toward more sustainable tourism models.
The Pressure on Local Resources
Beyond the environmental costs of air travel, the increasing number of tourists places substantial pressure on local resources, including water, energy, and waste management systems. The Canary Islands have a fragile ecosystem, and the growing influx of visitors threatens to exacerbate existing environmental challenges.
Water Scarcity Issues
The Canary Islands have limited freshwater resources, relying heavily on desalination plants to provide potable water to residents and visitors. Increased tourism results in higher water consumption, further straining existing resources. Overuse of water can negatively impact local agriculture, biodiversity, and the well-being of island residents.
Waste and Pollution Management
Tourist-generated waste is another significant concern. More visitors mean higher levels of plastic waste, sewage, and general pollution, which require effective waste management strategies. However, many islands struggle with insufficient infrastructure to handle the volume of waste generated by mass tourism.
Economic Benefits vs. Sustainability Challenges
Tourism is undeniably the economic backbone of the Canary Islands, accounting for a significant portion of GDP and employment. However, relying too heavily on mass tourism poses long-term risks.
Over-Tourism and its Consequences
The influx of millions of tourists can lead to overcrowding, environmental degradation, and strain on public services. Popular areas such as Tenerife’s Teide National Park and Lanzarote’s Timanfaya National Park face heavy footfall, leading to soil erosion, loss of biodiversity, and deterioration of natural landscapes.
Economic Dependence on Tourism
While tourism generates significant revenue, economic dependence on a single sector makes the region vulnerable to external shocks. The COVID-19 pandemic demonstrated how fragile tourism-reliant economies can be when travel restrictions cause sudden declines in visitor numbers. Diversifying the economy by promoting other industries such as renewable energy, agriculture, and technology can help build resilience.
Strategies for Sustainable Tourism in the Canary Islands
To ensure long-term sustainability, the Canary Islands must adopt strategies that balance tourism growth with environmental protection and social well-being.
1. Promoting Eco-Tourism and Sustainable Travel Practices
Encouraging eco-friendly tourism, such as nature-based and cultural tourism, can help minimize the negative impact of mass tourism. Promoting slow travel and longer stays rather than short, high-impact visits can also reduce per capita emissions.
2. Investing in Green Aviation Technologies
Airlines and governments must invest in sustainable aviation technologies, such as biofuels, electric planes, and carbon offset programs. Incentivizing airlines to operate more fuel-efficient flights and supporting research into alternative aviation fuels can reduce the carbon footprint of travel to the islands.
3. Strengthening Local Infrastructure
Upgrading water management, waste disposal, and energy systems to accommodate growing tourist numbers sustainably is essential. Expanding renewable energy sources like wind and solar power can help reduce dependence on fossil fuels and make tourism operations greener.
4. Implementing Visitor Quotas and Sustainable Tourism Taxes
Introducing visitor quotas for popular natural attractions can help prevent over-tourism and environmental degradation. Additionally, implementing tourism taxes aimed at funding conservation and sustainability projects can generate revenue to offset the negative impacts of mass tourism.
5. Diversifying the Economy
Investing in alternative industries such as renewable energy, agriculture, and digital technology can reduce economic dependence on tourism. By creating job opportunities in these sectors, the Canary Islands can build a more balanced and sustainable economy.
Conclusion: Can the Canary Islands Achieve Sustainable Tourism?
The Canary Islands face a complex challenge in balancing economic benefits with environmental sustainability. While tourism is a crucial economic driver, the overreliance on air travel and the strain on local resources pose significant risks. Sustainable tourism strategies, investment in green technologies, and diversification of the economy are essential to ensuring that the islands remain a thriving and environmentally responsible destination.
As the number of visitors continues to rise, policymakers, businesses, and tourists must work together to adopt sustainable travel practices that protect the Canary Islands’ unique ecosystems and cultural heritage for future generations.
