Exploring different cultures and traditions in various safe destinations is quite common in today’s world. Travelling with family for vacation or going on a business trip can be both enjoyable and rewarding. However, the excitement of exploring new places can impact the environment, especially depending on personal transportation choices. According to the International Energy Agency, the transportation sector accounts for 19.2% of global carbon dioxide emissions, and this figure is projected to increase without decisive action.
Sustainable travel is not just about the mode of transportation; it encompasses everything from prioritizing waste reduction to choosing eco-friendly accommodations and supporting local economies.
We must learn the most sustainable ways to travel, why sustainable travel matters, and how you can contribute to a future with lower CO2 emissions.
What Is Sustainable Travel?
Sustainable travel is about making environmentally conscious choices to minimize damage and reduce your carbon footprint when visiting new destinations. It involves the responsible use of resources and living sustainably to protect local ecosystems.
At its core sustainable travel means:
- Using public transportation instead of private vehicles.
- Reducing waste by not travelling with single-use plastics or using any while visiting.
- Supporting environmentally responsible businesses, from eco-friendly hostels to local artisans.
- Adopting green habits like minimizing energy consumption, and water use, and opting for environmentally friendly activities.
Sustainable travel fosters a deeper understanding of the local culture, promotes authentic interaction and builds appreciation for different ways of life.
The Importance of Sustainable Travel
Sustainable travel is essential to ensuring that tourism remains a positive force connecting different cultures. Over-tourism, cultural erosion, and environmental degradation threaten the peace and serenity of various tourist attractions. By practising mindful travel, we can ensure that cultural heritage is respected and iconic destinations are preserved.
Environmental Preservation
Over-tourism can harm unique ecosystems. From coral reefs to rainforests, delicate ecosystems are vulnerable to the pressures of mass tourism. Over-tourism often leads to actions like littering, which defaces cultural and natural heritage sites.
For instance, Australia’s Great Barrier Reef has been threatened by climate change and tourism-related damage. The reef generates over $6.4 billion annually from tourism, yet mass tourism has led to coral bleaching and habitat destruction.
Dr Terry Hughes, a leading marine biologist from James Cook University, emphasizes that “without immediate and aggressive intervention in how we manage tourism and coastal development, coral reefs like the Great Barrier Reef will continue to deteriorate, and we will lose a significant part of the Earth’s biodiversity.”
Economic Growth and Local Benefits
Sustainable travel also involves supporting local economies. Purchasing from local businesses, dining at family-owned restaurants, and staying at locally-owned accommodations help small businesses grow and create employment opportunities.
In countries like Thailand and Vietnam, sustainable tourism has bolstered small businesses within local communities. Tourists who buy from local artisans and spend money on small businesses contribute to reducing poverty in these areas. According to a study by the International Labour Organization (ILO), for every $100 spent in a destination, approximately $70 stays in the local economy when directed toward local businesses, compared to only $20 when spent on international chains or large corporations.
Conservation of Cultural Heritage
Tourism can play an important role in preserving cultural heritage, but it also remains a major threat to it. When tourists show little or no respect for local customs, overcrowd sacred sites, or purchase mass-produced souvenirs that erode authentic culture, they endanger the heritage of these communities. Sustainable travel encourages eco-tourism by educating tourists on the importance of respecting local traditions and learning about the cultures of new destinations, rather than disrespecting them.
Reducing Over-Tourism
Over-tourism refers to the overcrowding of tourist attractions, which occurs when a destination receives more visitors than it can sustainably support. This is common in places like Machu Picchu, Bali, and Venice. Over-tourism often leads to environmental degradation, strains local infrastructure, and diminishes the quality of life for residents. Ecotourism seeks to alleviate pressure on overcrowded locations by encouraging tourists to visit lesser-known destinations.
Many tourist destinations are implementing measures to reduce overcrowding. For example, Bhutan has developed a ‘high value, low impact’ tourism policy to limit the number of visitors.

Effects of Transportation on the Environment
Transportation remains a major contributor to carbon emissions in the travel industry. According to a report by the International Council on Clean Transportation (ICCT) in 2021, air travel alone accounts for 2.5% of carbon emissions.
Table: Environmental Impact by Mode of Transport
| Mode of Transport | CO2 Emissions (g CO2 per passenger-km) | Other Environmental Impacts |
| Airplane (long haul) | 285 | High water vapor emissions, noise pollution |
| Car (gasoline) | 250 | Air pollution, land use for infrastructure |
| Train (electric) | 14 | Minimal, depends on energy source |
| Bicycle | 0 | None |
| Bus | 68 | Moderate air pollution |
| Ship (cruise) | 390 | Water pollution, invasive species spread |
Land Transportation
While air travel tends to be the main focus in discussions about transportation emissions, the contribution of gasoline and diesel vehicles is sometimes overlooked. A report by the U.S. Environmental Protection Agency (EPA) estimates that transportation is responsible for 29% of total greenhouse gas emissions, with a significant portion generated by personal vehicles.
Recommendations: Opt for electric or hybrid vehicles when possible. According to a study by the Union of Concerned Scientists, electric vehicles produce about 50% fewer emissions than gasoline-powered vehicles, even when accounting for the electricity generation process
Marine Transportation
A report by Transport and Environment suggests that the shipping industry is responsible for approximately 2 to 3% of global carbon emissions, generating about 940 million tons of CO2 annually. Large vessels also contribute to water pollution by releasing ballast water, which introduces invasive species into ecosystems, and through oil spills.
Countries are taking steps to reduce pollution caused by marine transportation. Norway, for instance, is lowering its marine carbon footprint by investing in electric ferries and exploring green hydrogen as an alternative fuel source.
Aviation and Its Impact
The aviation industry generates millions of tons of carbon dioxide. According to a report, the industry contributes significantly to global greenhouse gas emissions. The ICCT also reports that, while only a small percentage of the global population uses air travel regularly, the emissions produced are disproportionate. For instance, frequent flyers, who account for only 1% of the global population, are responsible for over half of global aviation emissions.
The aviation sector is advancing technologically, with companies like Boeing and Airbus developing next-generation aircraft that could reduce fuel consumption. Airlines like KLM and United are also investing in sustainable aviation fuels (SAFs) and carbon offset programs to mitigate their environmental footprint.
Climate Change and Transportation
Climate change is creating new challenges for the transportation industry.
Rising sea levels, changing precipitation patterns, and increased storm intensity all pose risks to transportation systems.
Sea Level Rise and Coastal Transportation
Sea levels are expected to rise, and this will continue to affect transportation infrastructure, especially in coastal cities. Ports, railways, and airports near coastal regions are likely to experience serious flooding and storm surges.
Extreme Weather and Heat
Droughts, floods, and hurricanes are extreme weather events that are occurring more frequently due to climate change. These events not only threaten the physical infrastructure of transportation systems but also their safety and reliability. For example, recurring wildfires in California have led to delayed flights, damaged railways, and road closures.
Inland regions are also affected, as heat waves can buckle rail tracks and cause road surfaces to crack. The EPA notes that transportation systems in both coastal and inland regions must adapt to climate risks to maintain resilience in the face of climate change.
