How I Vet Sustainable Luxury Properties

Every recommendation begins with the destination, not the hotel. I research the ecosystem first — the conservation landscape, the community context, the environmental pressures — and then identify properties that claim to operate sustainably within it.

This means understanding whether a property sits in a national reserve, a private conservancy, or on community-owned land. It means knowing the migration corridors, the wildlife pressures, the local employment landscape. A property cannot be evaluated in isolation from the place it occupies.

I build a long list of properties that present themselves as sustainable through their marketing, press coverage, or industry reputation. This is where the vetting begins.

I visit every property's website and read it carefully. Not for the aesthetics, but for the language. There is a significant difference between a property that says "we are committed to sustainability" and one that says "we recycled 92% of our waste in 2024, measured and audited by [named organisation]."

I look for specificity. Named partners, published numbers, documented timelines, and a dedicated sustainability page with measurable targets, rather than a paragraph of aspirational language tucked into the 'About' section.

This step alone eliminates a significant number of properties. When the language is vague and the specifics are absent, that tells me something — either the work isn't being done, or it isn't being measured.

If a property claims sustainability credentials, I verify those claims against the certifying body directly. Not all certifications carry equal weight. The benchmark I use is recognition by the Global Sustainable Tourism Council (GSTC) — the international body that sets the baseline standards for sustainable tourism worldwide.

GSTC doesn't certify properties directly. Instead, it recognises certification bodies whose audit processes meet international standards. When a property holds a certification from a GSTC-recognised body, it means their sustainability claims have been independently audited — not self-reported.

I cross-reference every certification claim. If a property lists a certification on its website, I check the certifier's public database to confirm it's current. Certifications lapse, standards change, and a 'Gold' rating from five years ago may no longer be active.

Not every property doing meaningful sustainability work holds a formal certification. Some (particularly smaller, owner-operated lodges) embed conservation into their business model without pursuing external accreditation. That doesn't disqualify them from my list.

When there is no certification, I search for other forms of published documentation: annual sustainability reports, impact summaries, conservation partnership announcements, community development updates. I look for named organisations, financial transparency, and measurable outcomes.

A property that publishes a detailed annual report, even without certification, is demonstrating accountability. A property that has neither certification nor published documentation is asking me to take their word for it.

This is where the process shifts from research to dialogue. I reach out to properties directly, typically through their sustainability team or general management. I ask specific questions about their practices, documentation, and future commitments.

The way a property responds tells me as much as what they say. Properties with genuine programmes answer quickly, with specifics. They're accustomed to the questions because they've built systems to track and share the answers. Properties that deflect, delay, or respond with marketing language instead of data raise concerns.

I am not looking for perfection. I am looking for honesty, specificity, and a trajectory of improvement. A property that says "we're at 40% renewable energy and targeting 75% by 2028" gives me far more confidence than one that says "we care deeply about the environment."

If a property passes the desk research — whether through certification, published reports, or convincing direct dialogue — I arrange a site visit. Properties that already hold credentials are prioritised, but I also make exceptions for properties can demonstrate genuine commitment.

Sometimes I visit specifically because I want to see whether a property's early efforts could develop into something worth recommending. Not every property needs to be perfect today, but I want to see that the foundations are real.

A site visit reveals what no website, report, or email exchange ever can. It shows you what sustainability looks like when it's embedded in daily operations versus when it exists only in a PDF. Here is what I observe:

When I visited properties across Kenya in July 2025, I saw the full spectrum. Properties with beautiful sustainability pages and nothing behind them. Properties with no certification at all that were doing extraordinary work because the owners believed in it, they just hadn't formalised the documentation.

That range is precisely why site visits matter. Documentation gets you to the door. What you see when you walk through it determines the recommendation.

The most revealing conversations are not always with management. Sometimes they are with housekeeping staff, kitchen teams, guides, and gardeners. These are the people who live the property's sustainability practices every day (or not).

I ask staff where they're from; whether they've received training beyond their specific role; how long they've worked at the property; whether their families benefit from community programmes; whether they know the names of the conservation organisations the property partners with.

When sustainability is genuinely embedded in a property's culture, staff at every level can speak to it. They know the water system works because they maintain it. They know the community school was built because their children attend it. They can name the local NGO because they see the rangers every day.

When sustainability exists only in the marketing department, staff outside management often have little awareness of the claims being made on the property's behalf. That gap — between what the website says and what the team on the ground knows — is one of the most reliable indicators I've found.

I also cross-check information. If a property tells me they employ 80% local staff, I observe whether that aligns with what I see and hear during my stay. If they claim to have eliminated single-use plastics, I check the bathroom, the kitchen, the staff areas. If they say they fund a community school, I ask whether I can visit it.

This isn't about catching properties out. It's about understanding where they genuinely are in their sustainability journey, and whether the trajectory matches the marketing.
