IMEX America 2025 Sets New Sustainability Benchmark With Seventh Zero-Waste Milestone
As global expectations around sustainability continue to rise, event organisers are under increasing pressure to move beyond good intentions and deliver measurable results. The newly released Event Sustainability Report from IMEX America 2025 offers exactly that, providing an honest and detailed look at how one of the world's largest business events trade shows is turning environmental ambition into hard data. For African event professionals, destination marketers and MICE specialists, the findings offer valuable lessons that can be adapted to shape more responsible events on the continent.
Developed in partnership with sustainability consultants MeetGreen®, the report highlights notable achievements in waste diversion, materials management, food recovery and measurement, while also being refreshingly transparent about the areas that still require attention. This balanced approach reflects a growing industry recognition that sustainability progress must be tracked, communicated and continually improved.
One of the report's headline achievements is that IMEX America has maintained its zero-waste event designation for the seventh consecutive year, successfully diverting 90 per cent of its waste stream away from landfill and incineration. Remarkably, this milestone was reached even as the 2025 edition became the largest in the show's history, proving that scale and sustainability are not mutually exclusive.
The numbers behind the achievement are impressive. The show eliminated the equivalent of 50,615 plastic bottles by using refill stations and water coolers, averaging around 2.8 bottles saved per attendee. Carpet use was reduced by 5,280 square metres, a 14.5 per cent drop compared to the previous year and roughly the size of two tennis courts. In addition, 87 per cent of the carpet was returned to inventory and stored locally for future events, cutting down on both waste and repeated production. The food and beverage programme also focused on local sourcing, with menu ingredients drawn from within an 804-kilometre radius of Las Vegas, reducing transport-related emissions and supporting regional producers.
Beyond the numbers, the report has become a key tool in demonstrating IMEX's wider company-level sustainability strategy, which centres on turning intent into measurable impact. Central to this strategy is a target to reduce carbon emissions by 20 per cent by 2030. To support that goal, IMEX expanded its use of isla's TRACE platform across its supply chain, successfully capturing data for 90 per cent of participant air and ground travel. This level of measurement gives organisers a much clearer view of where emissions actually occur and where meaningful reductions can be made.
Another important step was the launch of the show's first recovery programme for polyester banners and structural booth materials. This initiative rescued an estimated 1,133 kilograms of polyester, which was donated through Mandalay Bay community channels to be repurposed for livestock shade, bedding and cleaning applications. It is a strong example of circular thinking that could easily inspire African event organisers to explore similar partnerships with local communities, farmers and social enterprises.
Reflecting on the results, IMEX Chief Financial Officer David Harrison stressed the importance of honesty and measurement. He noted that as IMEX America grows, so does the complexity of its sustainability challenge, particularly around waste, materials, catering and attendee travel. He acknowledged strong progress in maintaining the zero-waste status, reducing material use and improving emissions tracking, but was open about the fact that participant travel remains the single largest contributor to event-related emissions. By sharing both wins and shortcomings, IMEX hopes to help the wider industry accelerate its own sustainability journey.
For Africa's fast-growing meetings and events sector, the report offers a practical template. As more African cities position themselves to host regional and international conferences, embedding sustainability from the planning stage will become a serious competitive advantage. Delegates, sponsors and corporate clients are increasingly asking hard questions about environmental impact, and destinations that can respond with credible data will be best positioned to win future business.
