Tourism & the Environment: A Delicate Balance
Level
Tourism, a significant contributor to the global economy, treads a fine line between exploitation and preservation. As travellers seek out the world's wonders, they inevitably leave footprints - some beneficial, others detrimental. This article unpacks the complex relationship between tourism, the environment, and climate change, exploring the balance we must achieve for a sustainable future.
👉 In this article, we explore the tension between the benefits of tourism and its environmental impact.
Tourism, the environment, and climate change
Tourism - one of the world's largest industries, worth 7.6% of global GDP every year - has a significant impact on the environment, both positive and negative. On the one hand, it can lead to a greater appreciation for nature and conservation, as tourists explore pristine beaches, lush forests, and scenic landscapes. This appreciation can translate into increased funding for national parks, wildlife conservation, and the preservation of cultural heritage sites. For example, the revenue generated by the millions of tourists visiting Australia's Great Barrier Reef also helps fund conservation efforts to protect this unique ecosystem.
However, the large numbers of travellers can also strain these natural wonders. Mass tourism - where the number of tourists outpaces an area's capacity - can damage ecosystems, disrupt or harm local wildlife, and lead to pollution. Venice, for example, has seen its canals crowded with boats and its historic streets thronged with visitors, leading to accelerated wear on its historic sites and increased pollution in its waters. In response, Venice has introduced a €5 fee for day-trippers and placed limits on tour group sizes to manage the overwhelming influx of visitors. Other destinations, such as Rome and New Zealand, are also increasing tourism-related charges as a way to mitigate environmental pressures.
Meanwhile, despite the push for sustainability, tourism emissions are rising at an alarming rate. Between 2009 and 2020, global emissions from tourism grew by an average of 3.5% per year - twice as fast as emissions in other industries. By 2019, tourism was responsible for 5.2 gigatonnes of CO₂, nearly 9% of global emissions. This trend underscores the urgent need for more effective sustainability measures that go beyond voluntary initiatives.
While tourism contributes to climate change, global warming also has a profound impact on the tourism industry itself. Popular destinations like the Maldives face the threat of rising sea levels, while natural wonders like the Great Barrier Reef are endangered by coral bleaching due to warmer oceans. Additionally, ski resorts are increasingly struggling with shorter seasons due to dwindling snowfall. This reciprocal relationship between tourism and climate change highlights the urgent need for sustainable practices within the industry.

How does tourism negatively impact the environment?
Harm to the natural environment
One of the most significant negative impacts of tourism is the degradation of natural environments. Tourist hotspots, particularly those in ecologically sensitive areas, frequently undergo habitat destruction due to infrastructure development. For example, the construction of hotels, resorts, roads, and other tourism facilities can result in deforestation, alteration of land, depletion of natural resources, and disruption to local ecosystems. In places like Bali, once-idyllic beaches are now flanked by sprawling resorts, affecting marine life and leading to significant erosion of the shoreline.
Waste management issues
Waste management poses another challenge. In many popular destinations, the influx of tourists surpasses the local waste management capacity, leading to pollution. For example, Mount Everest, often referred to as the "world's highest garbage dump" is littered with oxygen cylinders, plastic waste, and even camping equipment discarded by climbers. Such uncontrolled waste not only spoils the landscape but can also contaminate local water sources, impacting both human and wildlife populations.
Water scarcity
Water scarcity is an often-overlooked repercussion of tourism. Many tourist-heavy regions face immense pressure on their freshwater resources, either due to overconsumption by hotels and resorts or by diverting them for recreational activities. Golf courses, particularly in arid regions, consume vast amounts of water, putting local communities at risk. Islands like Santorini in Greece have seen their freshwater reserves deplete significantly, forcing them to import water or rely on desalination.
Light and noise pollution
Noise and light pollution are additional concerns in areas with heavy tourist traffic. The constant hum of boats, vehicles, and human activity can disturb wildlife (including vulnerable and endangered species), affecting their natural behaviours and breeding patterns. Sea turtles, for example, which rely on the moonlight to find their way from the beach to the ocean, can be disoriented by the bright lights from beachfront properties, making their survival even more precarious.
Invasion of non-native species
The introduction of non-native species, whether unintentionally through transported goods or deliberately for tourist attractions, can upset the ecological balance of an area. In the Galápagos Islands, introduced species like goats and rats have wreaked havoc on the local flora and fauna, prompting extensive (and expensive) eradication programs.
How does tourism contribute to climate change?
Another major concern is how tourism substantially contributes to climate change:
Air travel emissions
Aviation is a significant contributor to global carbon emissions, previously estimated at 2% annually. However, new research shows that aviation is responsible for 52% of all direct emissions from tourism, making it the largest single contributor to the sector’s carbon footprint. While airlines promote sustainability efforts, these initiatives often fall short due to lobbying efforts that allow carriers to sidestep regulations by using only small amounts of sustainable fuel.
Increased energy consumption
Hotels, resorts, and other tourist accommodations often consume vast amounts of energy for heating, cooling, and lighting. This is especially true for luxury and high-end facilities that offer amenities like heated pools, spas, and air-conditioned rooms. Accommodation-related energy use is the second-largest contributor to tourism emissions, accounting for 34% of indirect CO2 emissions.
Transport within destinations
Once tourists arrive, they use local transportation, often in the form of cars, buses, and boats, which emit greenhouse gases. Rental car services and tour buses can significantly increase the carbon footprint of a vacation.
Cruise ship emissions
Cruise ships have surged in popularity over recent decades. These floating hotels consume massive amounts of fossil fuels, emitting not only CO2 but also other harmful pollutants into both the air and ocean. In fact, the largest cruise ships have doubled in size since 2000, contributing to a significant increase in CO2 emissions. This highlights the urgent need for more effective regulations in the industry.
Over-reliance on non-renewable resources
Many tourist hotspots are yet to transition to renewable energy sources. Their dependency on coal, oil, and gas for power generation further exacerbates greenhouse gas emissions.
Food production and consumption
Tourist destinations often need to import food to cater to the diverse and increased demands of visitors. This transportation, coupled with the preference for non-local foods, has a sizeable carbon footprint.
Land use and carbon sequestration
As mentioned earlier, the construction of tourist facilities can lead to deforestation and soil erosion. Not only does this result in the loss of wildlife habitats, but environments such as forests also play a crucial role in carbon sequestration, helping to absorb and store carbon dioxide. Their loss not only means increased CO2 emissions from construction but also a reduced capacity for the environment to offset those emissions.
“ 👉 In essence, while tourism can bring economic benefits to many regions, its role in climate change cannot be ignored. Sustainable and responsible tourism is crucial to mitigate these adverse effects on our environment. ”

Are there any benefits to tourism?
Tourism, for all its pitfalls, has also proven to be a crucial sector for many countries and environments. In numerous regions across the globe, tourism is the primary source of income, playing an instrumental role in sustaining economies and driving development. For countries with limited industrial or agricultural potential, the allure of their natural or cultural heritage can become their most lucrative asset.
To help put this into context, let's take the example of Kenya. The allure of the 'Big Five' - lion, elephant, buffalo, leopard, and rhinoceros - and the vast, mesmerising landscapes have drawn tourists in droves. Recognising the economic potential, the Kenyan government has taken proactive steps to safeguard these natural assets.
National parks and reserves, which now cover a significant portion of the country, not only protect the iconic wildlife but also generate substantial revenue. The revenue accrued from entrance fees, safari tours, and accommodation often goes back into conservation efforts, ensuring a sustainable cycle. Moreover, the value attached to these animals as tourist attractions inadvertently offers them a shield against poaching, as their value alive exceeds their value in body parts. Without the economic incentive generated by tourism, such extensive conservation measures may not have been feasible or prioritised.
Beyond direct conservation, tourism can also be a catalyst for broader environmental awareness and education. Visitors often return home with heightened environmental and cultural consciousness. This can lead to global advocacy, funding, and support for preservation efforts.
What's more, responsible tourism creates jobs for local communities, offering an alternative to activities that might harm the environment, such as logging or mining. By providing training and jobs related to tourism - be it as tour guides, in accommodation, or in local crafts - communities can derive sustainable income without depleting their environment.
However, it's important to strike a balance. While tourism can be a tool for positive change, it needs to be managed with care, foresight, and a genuine commitment to sustainability. Only then can the potential benefits be harnessed without compromising the delicate ecosystems that make these destinations so special in the first place.

Tourism and climate change
Yet, even as more travellers embrace sustainable vacations and choose environmentally-friendlier modes of transport like trains or electric vehicles, we cannot overlook the unavoidable emissions associated with reaching distant or isolated destinations. Air travel remains a substantial hurdle in the path to fully green tourism. Despite the advances in aviation technology and improvements in fuel efficiency, flights continue to be a significant source of carbon dioxide and other greenhouse gas emissions, which intensify global warming.
Herein lies a complex dilemma. Many destinations, particularly remote or island locales, rely almost exclusively on air travel to usher in tourists. For these places, tourism is not merely an addition to their economy; it's a lifeline. Places like the Maldives, Fiji, or the Caribbean islands depend heavily on tourist inflows for their economic stability. The revenue from tourism not only bolsters their economies but also funds essential services and infrastructure projects. Yet, paradoxically, these destinations are among the most vulnerable to the impacts of climate change. Rising sea levels threaten to submerge island nations, and changing weather patterns disrupt the delicate balance of their ecosystems.
This catch-22 situation highlights the complexities of the challenges ahead. On one hand, these destinations and their local populations desperately need tourism. On the other hand, the carbon footprint associated with getting to these places exacerbates the global warming that places them at risk. As the world grapples with this issue, it underscores the importance of innovation in sustainable travel and the necessity for a global perspective on balancing economic needs with environmental responsibility.

The future of tourism
The future of tourism is marked by both challenges and opportunities. As global travel continues to grow, the need to address its environmental impact becomes increasingly urgent. The industry must transition towards sustainability, preserving the planet while still allowing people to explore its wonders.
Embracing sustainable tourism solutions
Eco-tourism and responsible travel
Eco-tourism, a growing segment within the travel industry, emphasises responsible travel to natural areas that conserve the environment, sustain the well-being of local people, and involve understanding and education. This form of tourism encourages minimal impact on the environment while providing economic benefits to local communities. For example, destinations like Costa Rica have successfully marketed themselves as eco-friendly hotspots, where tourists can enjoy the natural beauty while contributing to conservation efforts.
Renewable energy and green infrastructure
When it comes to tourism development, investing in renewable energy and green infrastructure is crucial for making tourism more sustainable. Hotels and resorts are beginning to adopt solar and wind power, reduce water usage, and implement waste reduction strategies. Moreover, the rise of green building certifications, such as LEED, in the hospitality industry reflects a growing commitment to sustainability. Cities like Copenhagen for example have pioneered green urban tourism, integrating bike-sharing programs, extensive green spaces, and energy-efficient public transportation.
Carbon offsetting and eco-friendly transportation
While the reduction of air travel emissions remains a significant challenge, carbon offsetting programs offer a way for travelers to mitigate their impact. Airlines and travel agencies are increasingly offering carbon offset options, allowing customers to invest in environmental projects that reduce greenhouse gases. Additionally, the promotion of eco-friendly transportation alternatives, such as electric vehicles, high-speed trains, and cycling, is gaining momentum. In Europe, there has been a marked shift towards train travel for short to medium distances, reducing reliance on flights.
Conservation and community-based tourism
Community-based tourism (CBT) focuses on empowering local communities by involving them directly in the tourism industry. This model ensures that the economic benefits of tourism are distributed fairly and that cultural and environmental integrity is maintained. By fostering a deeper connection between tourists and local cultures, CBT enhances the travel experience while promoting conservation and sustainable development. In places like Bhutan, where tourism is heavily regulated, visitors pay a sustainable development fee that contributes to the country’s conservation and cultural preservation efforts.
How individuals can reduce their environmental impact when traveling
As awareness of the environmental impact of travel grows, individuals are increasingly looking for ways to minimise their carbon footprint while still enjoying the benefits of exploring new places. Sustainable travel is not just about making better choices on the road; it’s about planning ahead and being mindful of the consequences of your actions. By adopting eco-friendly practices, travelers can contribute to the preservation of the environment and help mitigate the negative effects of tourism. Below are some actionable steps individuals can take to reduce their environmental impact while traveling.

| Reduce Waste | Carry a reusable water bottle, shopping bag, and utensils to minimise single-use plastic waste. Avoid products with excessive packaging. |
| Respect Local Wildlife | Avoid activities that exploit animals, such as riding elephants or visiting poorly managed zoos. Support ethical wildlife tours and sanctuaries that prioritise animal welfare. |
| Be Energy Conscious | Turn off lights, air conditioning, and electronics when not in use. Consider taking shorter showers and reusing towels to conserve water and energy. |
| Avoid Over-Tourism Hotspots | Explore less popular destinations to avoid contributing to over-tourism. This helps reduce the environmental strain on popular sites and offers a more unique travel experience. |
| Educate Yourself and Others | Learn about the environmental impact of your travel choices and share this knowledge with others. By raising awareness, you can help spread the importance of sustainable travel. |
A call to action
The future of tourism depends on the collective efforts of all stakeholders - governments, businesses, communities, and travelers. Policymakers must implement regulations that incentivise sustainable practices, such as carbon taxes on flights and stricter environmental standards for tourism operators. Businesses in the tourism industry must commit to sustainability, not just as a marketing strategy, but as a core operational principle.
Local communities should be empowered to manage tourism in ways that benefit them economically while preserving their cultural and natural heritage. Travelers, too, must embrace a mindset of responsibility, understanding that every journey has an impact and making choices that minimise harm to the environment.
“ The path forward for the tourism industry is clear: embrace environmental sustainability or face the long-term consequences of environmental degradation and climate change. By investing in green infrastructure and promoting responsible travel practices, the industry can lead the way in creating a future where tourism and the environment coexist in harmony. ”
