From the Green Globe-certified Sofitel Angkor to the bioclimatic jungloos of MAADS, and — regrettably in some cases — to gyms left permanently lit, air-conditioned, and nearly empty: an investigation into what eco-hotel certifications are really worth in a country where regulation remains fragile, and into the central role of training in building truly sustainable tourism. Important: all establishments mentioned have been visited by the magazine's editorial team.
Cambodia is waking up green. Or at least, it says it is. From Siem Reap to Kep, through Phnom Penh and the Cardamom forests, a new generation of hotels is brandishing labels, certifications, and commitments.
Solar panels, zero plastic, NGO partnerships, tree planting: the vocabulary of responsible tourism has made its way into almost every hotel lobby in the Kingdom. But behind the rhetoric, what is Cambodia's "green" really worth? The stakes are not trivial. In a country where environmental regulation remains largely inadequate, where certifications are voluntary and not mandatory, and where inspection capacity is limited, the line between genuine commitment and greenwashing can be thin — or even invisible to the average traveler.
A Rapidly Changing Sector, Still-Unclear Rules
Cambodia welcomed more than six million international visitors in 2024. Demand for more responsible tourism is growing. Lodges in the Cardamoms in Koh Kong have adopted renewable energy and local sourcing. Koh Rong and Mondulkiri have become ecotourism hotspots. But the regulatory infrastructure that should govern all of this? It is almost nonexistent.
The ASEAN Green Hotel standards — the regional reference framework — involve 11 criteria, but their application remains entirely voluntary. There is neither a legal obligation nor a penalty for hotels that claim to be green without practicing it.
"A certification is not an absolute guarantee. It is a signal — a starting point for a verification process, not a blank check." — Fundamental principle of hotel eco-certification.
This legal void creates a radical information asymmetry: hotels know what they are actually doing; travelers only see what they are shown.
École Paul Dubrule — Training, the Quiet Pillar of All Genuine Sustainability
Before even discussing solar panels or green labels, one must address a question that the Cambodian hotel industry too often sidesteps: that of human capital. A hotel can boast a Green Globe certification or a zero-plastic policy; if its staff have not been trained in sustainable practices, these commitments remain superficial posturing.
This is precisely the gap that the École d'Hôtellerie et de Tourisme Paul Dubrule has been filling for more than twenty years. Founded in 2002 and supported by Accor and the École Hôtelière de Lausanne, it has gradually established itself as one of the most recognized vocational schools in the hotel and tourism sector in Cambodia, having trained more than 4,400 Cambodians to date. Founded by Paul Dubrule, co-founder of the Accor group, following an eight-month bicycle journey between Fontainebleau and Siem Reap, the school was designed to offer hotel training to disadvantaged young people in a region still bearing the scars of the Khmer Rouge era. The founding gesture was already, in itself, an act of social sustainability: investing in human beings, not just infrastructure.
MAADS Hotels — The Quiet Innovator
Founded in 2006 by Alexis de Suremain, MAADS represents arguably the most original approach to sustainability in the Cambodian hotel sector. Its ecological philosophy predates the "green" trend — and this shows in its projects.
The Jungloo: When Architecture Becomes Air Conditioning
The Jungloo — a contraction of "jungle igloo" — is perhaps MAADS's most remarkable contribution to sustainable hospitality. This bioclimatic tent bungalow, specifically designed for hot and humid environments, exploits its double skin and cylindrical shape to generate a solar chimney effect, drawing cool air from the surrounding vegetation to cool its walls.
The Templation Angkor Resort, the group's flagship in Siem Reap, claims to be the first hotel in the Kingdom to have attempted to power the majority of its electricity needs through solar energy — 352 panels capable of producing approximately 1,000 kilowatt-hours on a sunny day. Green roofs, air conditioning limited to sleeping areas, local materials: the architectural coherence is real. In February 2025, MAADS went a step further: its battery-free cooling prototype, developed in partnership with the Cambodia Institute of Technology and researchers from INSA Lyon, was awarded the WWF's "Smart Cooling Champion" prize. A rare and credible external validation.
MAADS embodies a systemic sustainability that predates trends. Its main limitation: the absence of annual third-party international certification. Its commitment rests more on verifiable innovation than on labels.
Kep West / Knai Bang Chatt — The Unexpected Champion
Eighteen rooms on Cambodia's southern coast. A name little known outside responsible luxury travel circles. And yet: Knai Bang Chatt, a boutique resort operated under the Kep West umbrella, holds arguably the most demanding certification in the entire Cambodian hotel sector — and one of the rarest in the world. The resort is one of only six hotels worldwide to hold the Platinum Green Growth 2050 certification.
This exceptional positioning is not a marketing accident. For every international booking, ten mangrove cuttings are planted in partnership with Marine Conservation Cambodia and members of the local community. Each tree absorbs approximately 308 kg of CO₂ over 25 years — more than 7.7 tonnes of carbon offset per stay: a quantified and traceable carbon commitment, rare in the sector.
What is even more striking is the scale of the establishment relative to the ambition of its certification. Eighteen rooms is a structure where every operational decision is visible, every practice potentially verifiable, and where inconsistencies cannot be hidden behind size.
The Platinum Green Growth 2050 certification, which covers dimensions ranging from marine biodiversity to local social governance, demands a level of rigor that hotels ten times larger often struggle to meet. Knai Bang Chatt thus illustrates a productive paradox of sustainable tourism: the most modest establishments, when they have the will and the competence, can achieve levels of environmental performance that large complexes, despite their resources, rarely approach. In Kep province, a few kilometers from the local market's crab fishers and regenerating mangroves, this small, discreet resort may well be the gold standard of what responsible Cambodian tourism can produce at its best.
Anjali by Syphon — The Eco-Boutique Hotel with an Impeccable Supply Chain
Recognized as the Best Eco/Green Luxury Hotel in Southeast Asia at the World Luxury Hotel Awards 2019, Anjali by Syphon has built a solid reputation since its 2018 opening on concrete, consistent practices. The hotel is entirely plastic-free — from straws to water bottles, down to room key cards made from certified sustainable bamboo. But it is in its supply chain that the approach is most impressive: amenity trays are manufactured by Cambolac, a Cambodian company employing young deaf adults; baskets are made by Manava, woven by women artisans; in-room waste bins are produced by OSMOSE, an NGO promoting alternative livelihoods.
Even the hotel's suppliers receive their deliveries in plastic-free containers.
Anjali's limitation is paradoxical: despite the depth and coherence of its commitment, the hotel does not hold a major annually renewed third-party international certification. Its approach relies more on sector recognition — and the verifiable sincerity of its practices — than on continuous auditing.
Farmhouse Resort & Spa — Sustainability as a Complete Social Model
Approximately 65 km north of Phnom Penh, in Kampong Chhnang province, the Farmhouse Resort & Spa represents a unique case in the Cambodian hotel landscape: this boutique resort is part of the Smiling Gecko social organization and functions as a training hotel at the heart of a community agricultural project, with its 24 classic Khmer-style bungalow rooms and 10 contemporary suites. Smiling Gecko Cambodia acquired a small plot of rural land in Kampong Chhnang in 2014 to offer a living environment and agricultural training to families from disadvantaged neighborhoods.
The resort is its economic arm: every night booked directly funds the school, the farm, and community infrastructure. This model — tourism as a lever for rural development, rather than a foreign imposition on a territory — may represent the most authentic form of hotel sustainability. Here, no label is needed: the transparency is architectural. Guests can see the school from their room, eat vegetables grown twenty meters away, and join the staff on the morning farm rounds.
Terres Rouges Lodge — Sustainability Through Cultural Rootedness in Ratanakiri
In the far northeast of Cambodia, in Ratanakiri province — one of the most remote and biodiversity-rich areas in the country — the Terres Rouges Lodge, the only boutique hotel in the entire province, occupies the former residence of the provincial governor on the shores of Banlung Lake, combining a Cambodian villa and luxurious bungalows amid an exotic garden. The sustainability of Terres Rouges is not claimed through certifications — it is lived through territorial rootedness.
The lodge supports the AÏRAVATA project, a cultural, ecological, and social conservation initiative centered on the last elephants of Ratanakiri province, enabling genuine interaction with these animals in their natural habitat — the protected Okatieng forest — while transmitting the ancestral knowledge of the mahouts.
In a context where the lowland encroachment is rapidly transforming Ratanakiri — converting forests and tribal lands into intensive agriculture — an establishment that funds circuits with the Tampoun, Kroeung, and Jaraï ethnic minorities, while remaining the only quality accommodation in the province, plays a role as an ecotourism stabilizer that is difficult to quantify but essential. Sustainability here also means resistance to cultural erasure.
Hôtel Indépendance — Sihanoukville, Sustainability as Patrimonial Resilience
In a city whose face has been brutally reshaped by concrete and speculation in recent years, the Hôtel Indépendance in Sihanoukville embodies a form of sustainability that audit frameworks do not know how to measure well: historical continuity. Completed in 1964 and designed by the French architectural duo Leroy and Mondet as a symbol of the country's optimism following independence, the building — locally nicknamed "seven floors" as it was by far the tallest in the country — welcomed figures such as Catherine Deneuve and Jacqueline Kennedy, and served as a showcase for the royal family, with King Norodom Sihanouk personally overseeing the original interior decoration.
Today, nestled within 22 acres of tropical forest and gardens, on the edge of Sihanoukville Bay, the hotel takes initiatives to reduce its energy consumption and supports local communities, particularly disadvantaged children living in poverty. In an urban context where Sihanoukville has been ravaged by a decade of uncontrolled construction, keeping an exceptional modernist building alive on land threatened by speculation is in itself an act of patrimonial and environmental sustainability. The hotel's challenge remains aligning these stated intentions with a formalized and verifiable environmental strategy — the gap between discourse and data has yet to be bridged.
Koh Russey Villas & Resort — Island Sustainability as a Paradigm
On Koh Russey (Bamboo Island), in the Koh Rong archipelago, the Alila Villas resort embodies a paradigm relatively rare in Cambodian hospitality: a sustainability embedded from inception in the architectural and operational foundations of the project. The resort's design was validated by EarthCheck, an Australian organization that certified the environmental sustainability domains and CO₂ emissions of Alila Villas Koh Russey.
The majority of the island's natural vegetation cover has been preserved, with low-density structures occupying only 15% of the 60-acre property. Other sustainable features include villa systems that automatically adjust lighting and temperature based on occupancy, a no-fishing exclusion zone around the resort to preserve the marine environment, and a dedicated nursery aimed at protecting more than 20 indigenous tree species on the island.
The hotel is part of the Global Sustainable Tourism Council, an organization that ensures tourism operates as sustainably as possible, from local sourcing or on-site production to the goal of carbon neutrality. The lesson of Koh Russey is that true island sustainability begins before the first shovel breaks ground: reserving 85% of the island for nature is a commercial decision that runs counter to land-optimization logic — and that is precisely why it deserves to be highlighted.
Sofitel Angkor Phokeethra — The Power of a Major Group
The Sofitel Angkor Phokeethra represents the most documented example of formal certification in the high-end sector. The Sofitel Angkor Phokeethra has received the Green Globe certification for the third consecutive year.
The commitments are impressive on paper: a partnership with Schneider Electric for carbon monitoring, collaboration with a consortium of 500 local farming families, a biodiversity program across 127 hectares including 75 bird species, and above all a social program that has provided free training in luxury hospitality to more than 1,500 disadvantaged young Cambodians over 16 years.
But what strikes guests staying at the establishment is that these efforts are not confined to brochures: they are perceptible. The vegetables served in the restaurant carry an indication of their local origin. The staff, clearly well-trained, can answer questions about the hotel's practices without reciting a script — a sign that the culture of sustainability has been internalized, not merely displayed. The garden, lively and carefully maintained, genuinely harbors observable biodiversity.
In the small everyday gestures, one senses that guidelines exist and are followed. That is precisely what certifications are meant to produce — and what some certified establishments fail to produce.
What distinguishes the Sofitel Angkor in the landscape of formal certification is less the accumulation of these indicators than their consistency over time. Three consecutive Green Globe certifications are not achieved through a one-off effort: they require a permanent internal measurement system, teams trained in daily sustainable practices, and governance that integrates environmental concerns into routine operational decisions — not just during audit weeks. The fact that the establishment belongs to a large international group (Accor) is not incidental: it has access to reporting tools, global standards, and external oversight that independent structures do not always have the means to afford. Sustainability in this case benefits from a group's infrastructure — which is both its strength and, for some, its limitation.
The Two Raffles — Heritage as New Commitment
The Raffles Grand Hotel d'Angkor in Siem Reap and the Raffles Hotel Le Royal in Phnom Penh occupy a unique place in Cambodian hospitality. They are not simply luxury hotels: they are living monuments, witnesses to Cambodia's twentieth-century history. The Raffles Le Royal opened in 1929; generations of diplomats, war correspondents, and world figures have stayed there. Both establishments have obtained Green Globe certification.
Their initiatives cover food waste reduction, energy consumption optimization, systematic recycling, and progressive local sourcing. Both Raffles are also involved in community activities, annual tree planting, and sustainable management training for their teams. The Raffles Le Royal distinguished itself as Cambodia's first "plastic-free" hotel — refillable glass bottles in all rooms, elimination of single-use plastics throughout all its spaces.
La Plantation Kampot — Agricultural Sustainability as the Hotel Foundation
About thirty minutes from Kampot, on the gentle hills overlooking the Gulf of Thailand and Phu Quoc island, La Plantation occupies a singular place in this panorama of sustainable Cambodian accommodation — that of a project whose logic is the inverse of most establishments in this investigation. Here, hospitality is not the core project onto which a green approach has been grafted: agricultural sustainability is the foundation, and accommodation is merely its natural extension.
Launched in 2013 by a Franco-Belgian couple, Nathalie Chaboche and Guy Porré, La Plantation was built around the cultivation of Kampot pepper, a traditional local product they undertook to revive according to organic and fair-trade principles. The spices are grown traditionally, hand-harvested, and processed according to high quality and hygiene standards — the whole being certified organic by Ecocert. With ISO certification and exports to around fifty countries, the brand has helped put Cambodian pepper on the global gastronomic map.
La Villa de La Plantation — the accommodation arm of the project, with its few rooms in brutalist architecture on a hillside — resembles no other establishment in the region. La Plantation works closely with local producers to ensure responsible agricultural practices and fair working conditions. The property was built from traditional Khmer wooden houses, dismantled and restored on the site — a patrimonial gesture that reflects a territorial consciousness that goes far beyond mere environmental certification. Approximately 90% of the staff come from surrounding villages, and since its beginnings the project has supported a local school by funding annual scholarships for students from disadvantaged backgrounds.
La Plantation's limitation, from the perspective of this investigation, mirrors that of Anjali: the depth of commitment is real and verifiable, but it has not yet translated into an annually renewed international third-party hotel certification. The approach remains essentially carried by the Ecocert agricultural certification and the Kampot Pepper GI label — solid credentials for the spice sector, but ones that do not cover the operational practices of the accommodation itself. This is not a criticism: it is an invitation. An establishment of this coherence deserves to submit to an audit it would likely pass with flying colors.
Rosewood Phnom Penh — High-Altitude Sustainability
Perched across the top 14 floors of the Vattanac Capital Tower — the tallest building in the capital — the Rosewood Phnom Penh represents the most documented and ambitious example of urban hotel sustainability in Cambodia. In April 2025, the Rosewood Phnom Penh reaffirmed its commitment to environmental sustainability and community enrichment through a series of innovative initiatives, including the removal of 1,050 kg of "orphaned" plastics, the planting of 2,000 mangrove trees in Koh Kong province, and collaboration with Vattanac Property to clean riverbanks, collecting 900 kg of plastic waste in 2024.
On the culinary front, the Rosewood Phnom Penh launched an indoor hydroponic garden — the first of its kind in Cambodia — producing 70% of the hotel's leafy vegetables and aromatic herbs, reducing external supply needs and limiting transport-related emissions.
What sets the Rosewood apart from its competitors is the rigor of its certifications: the hotel received a three-star rating — the highest — from the Sustainable Restaurant Association's Food Made Good Standard program in October 2024, becoming the first hotel in Cambodia and within the Rosewood group to receive this distinction, with scores of 77% in sourcing, 83% in societal impact, and 85% in environmental initiatives.
In March 2025, the Rosewood group as a whole received a multi-site certification from the Global Sustainable Tourism Council, issued by Bureau Veritas, covering 47 properties across its three brands.
But it may be on the training front that the Rosewood Phnom Penh makes its most lasting contribution. Through its "Open Door" program, managed in partnership with the École d'Hôtellerie et de Tourisme Paul Dubrule, the Rosewood Phnom Penh has recruited more than 400 employees from rural or disadvantaged backgrounds since 2018, and has allocated significant funds to language, IT, and professional training. Today, the proportion of foreign staff has been reduced to just 3%, and most management positions are held by Cambodians. This localization of management is, in itself, a sustainability indicator that environmental certifications do not yet measure.
Amber Kampot — Five-Star Luxury as a Local Sustainability Lever
On the opposite bank from Kampot's colonial old town, facing the neoclassical National Bank building, Amber Kampot has established itself since its opening as the province's first — and so far only — five-star resort. Nestled on a two-hectare estate bordered by mangroves, at the foot of the Elephant Mountains, the establishment blends contemporary minimalism with Khmer forest aesthetics, in a collection of 25 pool villas designed to recede into the landscape rather than impose upon it.
On the environmental front, the commitments are concrete and verifiable. The resort operates on a hybrid solar micro-grid powered by 144 photovoltaic panels, covering the majority of its energy needs. A strict single-use plastic elimination policy applies throughout the establishment — ceramic dispensers replace individual bottles, and water bottles are refilled rather than discarded. Kitchen organic waste is given to local farmers, and a waste sorting system is in place. Mangrove protection initiatives complement this setup in a particularly fragile riverside ecosystem.
The social dimension of the project also deserves mention. The establishment sources ceramics, textiles, and rattan items from Cambodian artisans, and staff training is an explicit lever for developing local livelihoods. In a province where international-quality hospitality was virtually nonexistent, the very existence of a resort at this level creates a demand for skills — and therefore an outlet for local hotel training.
Amber Kampot's limitation at this stage is one shared by several establishments in this investigation: the absence of an annually renewed international third-party certification. The practices are real, the investments tangible, but they rest on internal communication rather than contradictory external auditing. In a region where Kampot is only just beginning to establish itself on the responsible tourism map, Amber nonetheless represents a strong signal: sustainability and five-star luxury are not, here, oxymorons.
Uncomfortable Questions
Can a luxury hotel in Phnom Penh, proudly announced as certified, seriously claim a green certification while permanently air-conditioning and lighting two gym facilities that remain nearly empty throughout the day? This is the contradiction raised by a regular guest at an establishment in the capital. It perfectly illustrates the structural limitation of point-accumulation certifications: a hotel can compensate for poor practices in one area with excellent performance elsewhere.
The Green Globe auditor, present only on a periodic basis, will probably never check whether the gym is running at full capacity on a Tuesday at 2 p.m. in the off-season. Yet the standard itself requires measuring energy consumption and implementing measures to reduce it, which makes the question of real certification coherence all the more legitimate.
Can one finally tolerate a beachside hotel allowing its staff to fish small colorful reef fish for personal consumption? Coral reefs harbor essential biodiversity, and the fishing pressure on these fragile species is a well-known environmental concern.
What Certifications Don't See
Hotel certifications are based on annual declarative audits, supplemented by spot inspections. Yet an auditor who visits a hotel two days a year will never capture daily operating practices — prestige equipment kept running for appearances, air conditioning left on in corridors overnight, kitchen waste sorted during audit week and mixed together the rest of the time. Point-based certifications compound this problem: a hotel can accumulate points across several categories and "absorb" poor practices without ever correcting them.
The beauty of a certified botanical garden offsets an empty gym air-conditioned 24/7. Mathematically legitimate; ethically questionable. True transparency — what sustainability experts have been calling for for years — would require real-time publication of energy consumption data by zone, by equipment, accessible to guests and auditors alike. No Cambodian hotel is there yet.
What the Discerning Traveler Should Take Away
The hierarchy of evidence in hotel eco-certification is clear: an annually renewed certification from an independent third-party body is worth more than a one-time award, which is itself worth more than a statement of intent on a website.
By this criterion, Kep West, the Sofitel Angkor, the Raffles properties, and the Rosewood Phnom Penh stand out. MAADS, Anjali, Terres Rouges, and the Farmhouse nevertheless deserve recognition for the depth and coherence of their commitment — even without a label prominently displayed at reception.
And behind all these establishments, one institution deserves to be mentioned every time sustainable tourism in Cambodia comes up: the École Paul Dubrule. By training more than 4,400 Cambodians in close partnership with partners such as Accor and the École Hôtelière de Lausanne, it builds, diploma by diploma, the human foundation without which all the certifications in the world are nothing but paper.
But the ultimate lesson of this investigation may be the one an attentive guest unwittingly articulated: no label replaces direct observation. And sometimes, two empty gyms, permanently air-conditioned and lit, say more about the reality of a "green" commitment than any certificate framed in the lobby.
