The Future of Tourism: Balancing Growth and Environmental Responsibility

Tourism's Impact on Ecosystems

Dr. Amrik Singh Thakur
Tourism is intricately linked to the ecosystems it often disrupts. Natural wonders such as coral reefs, wetlands, and forests are not merely backdrops; they are integral to the tourism experience. Despite this, the industry continues to expand. According to UN Tourism, international tourist numbers reached 1.52 billion in 2025, reflecting a 4% increase from the previous year. The breakdown by region shows Europe leading with 793 million arrivals, followed by Asia and the Pacific with 331 million, and the Americas with 218 million. Projections for 2026 suggest a further rise to a record 1.57 billion international arrivals, marking a 2% growth from 2025, as per the WTM Global Travel Report 2026. However, the growth has been tempered by geopolitical tensions and rising costs, with international overnight arrivals increasing by 2% in early 2026 to approximately 307 million tourists.

As discussions commence at COP31 in Antalya on November 9, following biodiversity talks in Yerevan, the tourism sector faces a pivotal choice: to continue benefiting from nature while depleting it or to actively contribute to its restoration.

Addressing Emissions in Tourism

The tourism industry must confront its emissions honestly. Estimates indicate that tourism accounts for approximately 7.3% to 8.8% of global greenhouse gas emissions, equating to around 5.2 gigatons of CO2 equivalent annually—more than double the growth rate of the global economy. The aviation and road transport sectors are significant contributors, with air travel increasing by about 7% through October 2025. Despite technological advancements, the anticipated reductions in emissions have not materialized. Any serious dialogue regarding nature-based solutions must begin with this acknowledgment, as they cannot serve as a justification for continued unsustainable practices.

Overtourism exacerbates local environmental issues, leading to overcrowded trails, excessive water usage by hotels, and unmanaged waste, all of which place immense pressure on delicate ecosystems. When the carrying capacity of these areas is exceeded, both the ecosystems and local communities suffer, ultimately damaging the reputation of tourist destinations. Effective visitor management, seasonal distribution of tourists, and realistic limits on new developments are essential for ecological sustainability and should be integrated with restoration efforts rather than treated as separate initiatives.

The Importance of Restoration

Evidence supporting ecological restoration is compelling. Initiatives like reforestation, wetland restoration, and soil carbon sequestration can sequester carbon while providing habitats for wildlife, stabilizing slopes, and managing water resources. However, the effectiveness of these efforts hinges on their execution; studies indicate that restoring natural forests captures carbon more efficiently and sustainably than monoculture plantations. The joint IPBES-IPCC workshop report cautions against poorly designed measures that may harm biodiversity while yielding minimal climate benefits. Nature-based solutions must align with local ecosystems and be informed by indigenous knowledge. For the tourism sector, this transition involves moving beyond merely minimizing harm to actively restoring the landscapes that attract visitors.

This shift also raises questions of justice. Indigenous communities manage or hold rights to about a quarter of the world's land, including many natural areas that tourists seek to explore. Ecotourism can promote conservation only when these communities have genuine rights, equitable benefit-sharing, and a voice in decision-making processes. Restoration projects that displace local residents or exploit community land for carbon credits without consent perpetuate the very extractive practices that have led to the current crisis. Ensuring free, prior, and informed consent, secure land tenure, and transparent benefit-sharing is crucial for successful restoration efforts.

Collaboration for Effective Solutions

Collaboration is vital for addressing these challenges. The Intergovernmental Panel on Climate Change (IPCC) and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) are key scientific bodies guiding policymakers on climate and biodiversity issues. Despite their interconnectedness, these organizations only held their first joint workshop in December 2020. The IPBES's 2024 Nexus Assessment, which analyzed over 6,500 publications, found that isolated approaches often lead to trade-offs that integrated strategies can avoid. The tourism sector faces similar challenges, with various stakeholders—environment ministries, tourism boards, municipalities, and local councils—operating in silos, while conservation receives a mere 3% of global climate finance. No single entity can effectively restore a watershed that spans multiple jurisdictions and ownerships.

The local impacts of the global climate crisis are stark. For instance, Himachal Pradesh experienced significant monsoon losses in 2025, with rainfall 45% above normal, resulting in numerous landslides and flash floods that severely affected tourism. While climate change is a factor, poor land management practices have exacerbated the situation. Protecting vital ecosystems like forests and wetlands is not just an act of charity; it is essential for adapting to climate change.

A Blueprint for Sustainable Tourism

What might a practical plan for sustainable tourism look like? Here are five actionable steps that can be implemented within three years: First, measure: Require destinations and major operators to report their transport, energy, and waste emissions using established tourism accounting frameworks. Second, reduce: Prioritize rail and road-sharing, limit aviation-dependent growth, and electrify accommodations before considering any offsetting claims. Third, restore locally: Implement a small, transparent visitor fee collected through accommodation bills, earmarked for local restoration projects chosen by community committees. Fourth, build capacity: Train local residents in nursery management, monitoring, guiding, and enterprise accounting to ensure that restoration efforts create lasting jobs. Fifth, institutionalize collaboration: Create destination-level councils that unite stakeholders from forestry, tourism, disaster management, and local governance, sharing data and budgets. These steps require modest funding, existing legal frameworks, and ongoing coordination rather than new technologies.

The Role of Research in Tourism

It is important to note that the literature on tourism often portrays it as a contributor to emissions, a victim of climate impacts, and a potential source of conservation funding, but rarely as an organized participant in landscape restoration governed by community rights. There is a need for more evidence on the long-term performance of visitor-funded restoration and who benefits from it. This gap presents an opportunity for tourism scholars to contribute by testing the proposed model through comparative studies and sharing the findings openly. Interdisciplinary teams of ecologists, economists, anthropologists, and tourism managers, collaborating with local communities as co-researchers, are best positioned to undertake this work.

The message is clear: tourism must prioritize reducing emissions, restoring ecosystems, and sharing power equitably. The necessary tools are available, and evidence is accumulating. The upcoming negotiations will reveal whether governments and the industry are ready to embrace these changes. For scholars, educators, and practitioners in tourism, the challenge lies in transforming this moment into a capacity that communities can own. Delaying action will cost destinations their seasons and communities their futures.
