Sustainability is no longer a side conversation in the meetings industry — it is becoming central to competitiveness, profitability and destination appeal.
That was the clear message from a high-level panel discussion on “The Future of MICE & Sustainable Connectivity” at the TDM Global Summit Bangkok 2026, where hospitality leaders explored how environmental responsibility is moving from operational concern to strategic advantage in the business events sector.
Moderated by Sumate Sudasna, President Emeritus of Thailand Incentive and Convention Association and Chief Resilience Officer at Conference and Destination Management, the panel brought together Nick Downing of The Langham, Custom House, Michael Marshall of S Hotels and Resorts, Marisa Sukosol Nunbhakdi of Sukosol Hotels and Craig Bond of Pan Pacific Hotels Group.
Across the discussion, one theme emerged consistently: in MICE, sustainability is shifting from obligation to opportunity.
From compliance to commercial advantage
Once viewed largely as a cost centre, sustainability is increasingly being recognised as a revenue driver. For Marisa Sukosol Nunbhakdi, the business case is already clear.
She pointed to growing demand from multinational companies and event organisers specifically choosing green-certified venues because they need partners capable of supporting emissions reporting, carbon offsetting and broader ESG commitments.
For some buyers, sustainability credentials are no longer a preference — they are procurement criteria. “It has become a business value and a competitive edge,” she noted, reflecting how years of certification work are now translating into market access and bookings. Michael Marshall highlighted how sustainable meetings packages, including carbon-calculated “zero emissions meetings,” are already helping differentiate venues, while Craig Bond noted sustainability certifications are increasingly winning conference business across the group. The message was clear: sustainability is influencing demand.
Profitability and sustainability are no longer at odds
A recurring question in the session was whether sustainability investments pay off. The panel’s response was emphatic: yes.From energy-efficient systems and solar adoption to food waste reduction and water savings, panellists pointed to measurable returns that strengthen margins while reducing environmental impact.
For many hotels, electricity remains among the highest operating costs after payroll, making energy efficiency not just environmentally prudent but financially compelling. Some speakers also argued the discussion has matured beyond ROI alone. The real value, they suggested, lies not simply in short-term payback, but in long-term resilience. As Marshall put it, sustainability should not be treated as a KPI or isolated initiative, but embedded into the DNA of hospitality businesses.
Sustainable meetings are becoming experiential
Perhaps the strongest evolution discussed was how sustainability is moving from back-of-house systems into guest-facing experiences. For MICE organisers, this opens up new possibilities. Rather than limiting sustainability to offsetting emissions or reducing waste, hotels are increasingly integrating purpose-driven experiences into conferences themselves — from community engagement and conservation activities to urban farms, sustainability tours and reforestation programmes. Marshall described how even opting out of room servicing can be linked to tangible guest participation, such as tree planting initiatives.
For delegates, this transforms sustainability from an abstract policy into something experiential and memorable. And in MICE, that matters. Because increasingly, event planners are looking not just for venues, but for purpose-led experiences that add meaning to meetings.
Guests now expect authenticity — not greenwashing
If sustainability is becoming more visible, panellists warned it also has to be credible. Several speakers cautioned against superficial sustainability messaging, noting today’s travellers and corporate buyers are increasingly sophisticated and quick to spot greenwashing. Certification, transparency and measurable targets are becoming critical.
For Bond, globally accredited standards are helping bring accountability and trust. For others, the key is ensuring sustainability is not treated as marketing veneer, but operational reality. That includes staff training, supply chain decisions, building design and community engagement. As one panellist put it, if you do it, do it properly.
Thailand has a MICE sustainability opportunity
Beyond individual hotel strategies, the panel also turned to Thailand’s broader opportunity as a sustainable MICE destination. Several speakers argued the country has strong foundations — rich natural assets, hospitality expertise and growing industry momentum — but could move faster through clearer national standards and stronger policy support.
There was discussion around whether Thailand could adopt more structured national sustainability frameworks similar to other markets, helping accelerate adoption across both large and smaller operators. The consensus: the opportunity is significant, but coordination matters. And for a country where tourism remains economically critical, sustainability may increasingly be central to protecting long-term competitiveness.
The future of MICE may be regenerative
Perhaps the most striking idea to emerge from the session was that sustainable MICE is moving beyond minimising harm toward creating positive impact.
From coral regeneration and biodiversity initiatives to community engagement and local sourcing, the conversation increasingly pointed toward regenerative models — where meetings contribute to destinations rather than simply consume them. For Sukosol Nunbhakdi, that links back to a broader responsibility. Tourism, she argued, depends on the natural and cultural assets destinations have inherited. Protecting them is not separate from business — it is part of it.
Where sustainable connectivity goes next
If there was one takeaway from the session, it was that the future of MICE will be shaped as much by sustainability as by infrastructure or connectivity. Green certifications may win business. Purpose-led meeting design may deepen delegate engagement. And sustainable operations may strengthen both profitability and resilience. But perhaps most importantly, sustainability is no longer something the MICE sector can afford to add later. It is becoming part of the product itself.
And as this panel made clear, the future of business events may be defined not simply by how people connect — but by how responsibly they do so.
