Sustainable Tourism

Tourism is one of the most important economic sectors in Southeast Asia, contributing significantly to GDP, employment, and local livelihoods. Before the COVID-19 pandemic, the tourism industry generated 12,1% of ASEAN’s combined GDP and provided jobs to 42 million ASEAN people. It stimulates growth across multiple industries, including transport, hospitality, retail, and food services, and is a key driver of infrastructure development in urban and rural areas alike.

During the pandemic, international tourist arrivals plummeted by more than 80%, and tourism revenue dropped by 75%. After the World Health Organization (WHO) announced the end of the pandemic in May 2023, international tourist arrivals to ASEAN steadily increased, with a 153.09% year-on-year growth based on preliminary 2023 figures.

In addition to its economic role, tourism also helps to preserve cultural heritage, traditional crafts, and community identity, particularly in areas where local attractions are closely tied to history and nature.

However, tourism can also place pressure on the environment and local communities. Popular destinations face problems like solid waste build-up, water scarcity, pollution, and degradation of ecosystems. Local cultures may be commercialized, and uncontrolled tourism growth can widen inequality or displace long-standing communities. The very places that make tourism possible the beaches, temples, forests, rivers, and rural landscapes risk being destroyed by the very industry that celebrates them.

This is why the concept of sustainable tourism is no longer optional. It is a necessity. Across the ASEAN region, there is growing recognition that tourism must evolve to be more responsible, inclusive, and environmentally conscious. This thematic area explores how ASEAN Member States and their partners are moving toward more sustainable models of tourism. It highlights real-life practices, policy directions, and collaborative solutions that can support a tourism sector that brings long-term value without compromising the future.

Understanding Sustainable Tourism

Sustainable tourism is about meeting the needs of tourists, local communities, and the environment today and in the future. It involves carefully managing tourism’s impact to protect natural resources, promote cultural integrity, and ensure that economic benefits are shared fairly. It does not reject tourism but redefines how it is done, with more thoughtfulness, fairness, and care.

At its heart, sustainable tourism emphasizes minimizing environmental harm, supporting local economies, and preserving cultural and natural heritage. Rather than focusing on maximizing tourist numbers, it shifts attention to quality experiences, balanced growth, and long-term resilience. In practice, this can mean many things: reducing plastic use in hotels, protecting coral reefs from boat traffic, providing meaningful employment in rural areas, or integrating sustainability into tourism education and training.

Importantly, sustainable tourism is a shared responsibility. Governments set the policies and regulations, businesses shape the visitor experience, civil society raises awareness, and travellers themselves make choices that can reduce harm or create positive impact.

Tourism in ASEAN: Opportunity and Challenge

Before the COVID-19 pandemic, the ASEAN region had emerged as one of the world’s fastest-growing tourism destinations. With over 143 million international arrivals recorded in 2019, the sector had become a major contributor to the region’s GDP. Countries like Thailand, Malaysia, Vietnam, and Indonesia were among the global leaders in tourism growth. Even smaller economies and remote communities were experiencing the benefits of increased visibility and access to global markets.

While tourism positively contributed to GDP across ASEAN, some negative impacts and risks have been identified, affecting the environment, fauna, flora, and especially contributing to increasing greenhouse gas emissions.. Many tourism hotspots whether mountain villages or tropical islands faced strain from overcapacity. Waste management systems were overwhelmed, especially in areas with limited infrastructure. Marine litter became a frequent concern, with beaches and reefs suffering from the side effects of poorly managed tourism flows. Local water sources were depleted during high seasons, and the carbon footprint of tourism-related transport continued to grow.

These challenges have emphasized the role of green and ecotourism approaches in ASEAN.

The pandemic in 2020 caused a sudden pause in travel, deeply affecting millions who rely on tourism for income. But this pause also created space to reflect. Countries are increasingly developing policies to reduce carbon emissions, manage natural resources responsibly, and leverage their environmental and cultural assets to support sustainable tourism. Tour operators and communities have been exploring how to rebuild tourism in a more sustainable and resilient way.

ASEAN’s Commitment to Sustainable Tourism

The ASEAN Declaration on Sustainable Tourism, endorsed by Tourism Ministers in January 2022 during the 25th ASEAN Tourism Ministers Meeting, further affirms the region’s direction. It emphasizes the need for coordinated action, multi-stakeholder partnerships, and capacity building for sustainable destination management. These commitments provide a regional framework, but real change depends on how policies are implemented on the ground.

ASEAN and its Member States recognize the economic value and vulnerabilities of tourism and have taken important steps to guide the industry toward sustainability. The ASEAN Tourism Strategic Plan 2016–2025 outlines the region’s long-term vision: to develop Southeast Asia as a quality tourism destination that is sustainable, inclusive, and more integrated. The plan includes specific strategies to promote community-based tourism, strengthen environmental management in tourism destinations, and encourage responsible business practices.

This regional strategy is supported by national efforts. Many countries have developed sustainable tourism frameworks or eco-tourism master plans. For example, Thailand’s “Bio-Circular-Green” economic model includes sustainable tourism as a priority. Indonesia’s Clean Tourist Destinations campaign works to keep popular destinations waste-free. Cambodia, Vietnam, and Laos have invested in village-based tourism projects that combine conservation with cultural exchange.

Community-Based Tourism

One of the most powerful models of sustainable tourism in ASEAN is community-based tourism (CBT). Rather than being managed by outside investors or large companies, CBT involves local residents directly in planning, delivering, and benefiting from tourism.

In a CBT setting, visitors might stay in a family homestay, join a fishing trip with local guides, learn a traditional weaving technique, or help cook a community meal. These experiences are not only authentic but deeply respectful of the host community’s culture and environment. Across ASEAN, CBT has gained momentum in both remote and urban settings. In northern Laos, entire villages have created eco-tourism programs that help protect forests and rivers. In central Vietnam, heritage sites are maintained through tourism revenue managed by local cooperatives. In the Philippines and Indonesia, island communities host snorkeling tours, handicraft workshops, and traditional performances, using tourism to sustain cultural pride and environmental stewardship.

Yet CBT also faces challenges. It needs consistent training, marketing support, and quality standards to remain competitive. Without support, CBT can struggle to access mainstream tourism markets or maintain consistent visitor flow. ASEAN partners have worked to address these barriers through training programs, local dialogues, and peer learning exchanges.

Improving Waste Systems in Tourist Areas

One of the most visible signs of unsustainable tourism is litter on beaches, streets, hiking trails, and in waterways. Tourists often generate more waste than residents, and the seasonal nature of tourism puts strain on municipal waste services.

Through the AMUSE project and other programs, GIZ has supported cities in improving waste infrastructure and operations. This includes expanding waste collection coverage, supporting source segregation, developing recycling partnerships, and promoting public education campaigns. In tourism hotspots, where the image and cleanliness of the area are key to visitor satisfaction, such investments pay off quickly.

Better waste systems also mean less pressure on the marine environment. In coastal areas, leakage of plastic waste into the ocean threatens not only biodiversity but also the reputation of tourist destinations. No one wants to visit a dirty beach or snorkel in a sea of trash. Clean environments are essential for long-term tourism success.

Changing Traveler Behavior and Industry Practices

Tourism sustainability is not only about governments and infrastructure it’s about people. Travelers make choices every day that affect the places they visit. Whether it’s using a reusable bottle and preventing single-use plastics, following local customs, choosing eco-certified accommodations, or picking up litter. These small actions add up.

At the same time, it requires tourism businesses to create environments that support better choices. When hotels provide refill stations, tour guides explain cultural etiquette, or restaurants offer plant-based options, they nudge travellers toward sustainability without needing strict rules.

Behavioral change is most effective when it is simple, rewarding, and community-led. This is why the ASEAN Knowledge Platform provides materials such as communication templates, signage guides, and awareness-building toolkits for tourism operators. These helps translate sustainability into everyday actions for guests and staff alike.

Toward a Greener, Fairer, and More Resilient Tourism Future

The vision of sustainable tourism in ASEAN is not a distant dream. Across the region, cities are banning single-use plastics in tourist zones, resorts are installing solar panels, villages are offering immersive homestays, and travelers are becoming more conscious of their impact. But this transformation requires continuous effort. Sustainable tourism is a process, not a destination. It needs cooperation across sectors, investment in people and systems, and a shared understanding that tourism must contribute to, not take away from, the places it touches.

This platform supports that journey by offering knowledge, practical tools, and inspiration. Whether you’re a policymaker, a tour operator, a community leader, or a conscious traveller, your choices help shape the future of tourism in ASEAN.
