Sustainability is becoming a real procurement filter for European agencies and an increasing number of US and APAC corporate buyers. RFPs that didn't mention sustainability two years ago now include sections on carbon reporting, supplier ESG documentation, and DEI considerations. The agencies that can answer these well win more business; the DMCs that can document them win the agencies' confidence.
This is what Halia actually does on the sustainability side, what Thailand can genuinely deliver, and where the field is still mostly marketing.
The substantive sustainability levers
There are six sustainability levers that materially change a program's environmental and social footprint. They're not all equal in impact.
1. Hotel partner selection
The single highest-leverage decision. Some properties in Halia's network have substantive operational sustainability programs:
Six Senses Samui is the leader. The property runs an organic garden that supplies a meaningful share of in-house F&B, has eliminated single-use plastics across all guest touchpoints, runs in-house composting and food-waste tracking, and reports on biodiversity restoration in the property's grounds. Their program is independently verified and reported annually.
Conrad Koh Samui, Banyan Tree Samui, and Four Seasons Koh Samui all participate in their parent company's corporate sustainability frameworks (Hilton's Travel With Purpose, Accor's Planet 21 equivalent, Four Seasons' sustainability commitments). Property-specific implementation varies; we can pull the documentation per property on request.
Other properties in our network have lighter sustainability programs that read closer to marketing than operations. For programs where sustainability is a procurement requirement, we'll narrow the property recommendation to the verified leaders.
2. F&B sourcing
Plant-forward menus reduce program carbon footprint by approximately 35-45 percent vs. standard meat-heavy banquet menus. Local sourcing (Thai-grown produce, locally-caught seafood) reduces it further and supports the local economy.
Halia coordinates with hotel kitchens on plant-forward defaults, locally-sourced ingredient sourcing, and seasonal menu construction. None of this requires sacrificing F&B quality — Thailand's culinary tradition is naturally plant-forward and locally-sourced when executed well.
3. Transport optimization
Group transport in fewer, larger vehicles is more efficient than multiple small vans. Coordinating timing to share vehicles between activity streams reduces empty-vehicle miles. For programs where it makes sense, electric or hybrid vehicles are available through specific transport partners on Samui at a 15-25 percent premium.
4. Event production materials
Single-use signage, paper-based name tags, plastic-stem decor — these accumulate quickly across a multi-day program. Sustainable production substitutes (digital signage, FSC-certified paper, reusable decor elements) cost slightly more upfront but produce measurably less waste.
5. Carbon offsetting
Offsetting is the easiest single sustainability lever to implement. Reputable Gold Standard or Verra-certified offsets for the program's flights, ground transport, hotel emissions, and event production typically add USD 20-40 per participant.
The credibility of offsets has been criticized in some industry reporting. The current practical recommendation is: offsets are not a substitute for reducing emissions, but they're a meaningful signal of commitment when paired with the other levers above.
6. Community engagement
Programming a half-day visit to a local NGO, community project, or social enterprise during the program creates participant connection to the destination and meaningful local economic impact. Examples we've programmed: marine conservation work with a local research center, English-teaching support visits at rural schools, traditional craft workshops with women's cooperatives.
These add USD 50-150 per pax including transport, donation, and facilitator fees. Done well, they become the most-remembered moment of the program.
What Thailand actually delivers vs. what's marketing
The honest read on Thailand's sustainability landscape:
Genuinely strong:
- The Six Senses sustainability program is operationally serious
- Marine conservation programming through Ang Thong, Koh Tao Marine Conservation Initiative, and similar groups is real work
- Locally-sourced F&B is structurally available because Thailand's agricultural base is strong
- Hotel parent companies' corporate sustainability frameworks have meaningful implementation budgets
Mixed:
- Smaller hotel properties' sustainability claims often outpace their actual operational programs
- "Eco-friendly" marketing language is widespread; operational implementation varies
- Thailand's tourism industry overall has the sustainability conversation but is uneven on delivery
Weak:
- Carbon accounting infrastructure for tourism in Thailand is underdeveloped vs. the EU. Most measurement programs require Halia to coordinate with international providers rather than working through local frameworks.
- Single-use plastic continues to be standard in many tourism-adjacent operations (boats, beach activities, food vendors). Substantively eliminating it from a multi-day program requires intervention at every supplier.
What to put in your sustainability commitment
For most programs where sustainability is a procurement filter rather than the centerpiece, the right commitment package is:
- Hotel selection from the verified-sustainable shortlist (Six Senses primary, Conrad/Banyan Tree/Four Seasons acceptable)
- Plant-forward as the F&B default with meat options available rather than the inverse
- Plastic-free room and event amenities documented in writing
- Carbon offsetting via certified provider, line-item on the proposal
- One community engagement element programmed into the itinerary
- Post-program sustainability report with measured emissions
This package adds approximately 4-7 percent to total program cost (mostly carbon offsetting and community engagement) and produces a defensible sustainability narrative for procurement teams and participant briefing materials.
For programs where sustainability is the centerpiece — RFPs that lead with ESG, programs designed for impact-investor or sustainability-focused organizations — the package extends to full carbon measurement, biodiversity-positive activities, and operational deeper involvement with local conservation projects. Halia scopes these on request.
What to ask in your DMC RFP
If sustainability matters to your buyer, the questions to put in the RFP:
- Which of your hotel partners have independently-verified sustainability programs? Provide documentation.
- What is your standard practice on carbon measurement and offsetting?
- Can you provide post-program emissions reporting?
- What community engagement elements have you programmed into past similar programs? Provide examples.
- What is your operational practice on single-use plastics for the program duration?
- What is your supplier vetting process for sub-contractors (transport, AV, F&B vendors)?
Reputable DMCs will answer these in writing as part of their proposal. Vague or evasive answers are diagnostic.
