Sustainability is firmly on the agenda for most associations and their members in 2026, but when you’re bringing hundreds, sometimes thousands, of people together, reducing the environmental impact of a conference can feel like a pretty big task.
Don’t panic, we’re here with good news.
The most meaningful progress often comes from understanding where your biggest impacts are, making conscious decisions and then improving year on year. For our team at BeaconHouse Events, that starts with measurement. For every event we deliver, we create a TRACE carbon report, giving us a clearer picture of its environmental impact and helping us review progress, challenge our decisions and identify where we can make lower-carbon choices next time.
We got our heads together and looked at just some of the practical ways associations can start making a difference at your next event…
Start the sustainability conversation early
Sustainability shouldn’t be something you think about once the venue has been booked and the programme is already taking shape. We start the event planning journey by talking to our clients about their sustainability priorities from the outset, including through a sustainability survey which discusses things like:
What matters most to the organisation?
Where do they want to make progress?
Are there particular commitments or targets we need to consider?
By having those conversations early, sustainability becomes part of the decision-making process rather than an add-on at the end.
Look at how people are getting there
For many conferences, delegate travel can be one of the biggest contributors to the overall carbon footprint.
Choosing a venue with good rail and public transport connections can make a significant difference, as can giving delegates genuinely useful information about how to reach it without driving alone. Think beyond simply including the nearest train station on the website, why not provide walking routes, public transport options and car-sharing information, and make sustainable travel feel like the easiest choice for your guests. For the World Conference of Science Journalists (WCSJ), we’re working with you.smart.thing to help delegates make informed, lower-carbon travel choices as part of their journey to the event.
Make catering count
Food is another area where relatively straightforward decisions can have a meaningful impact.
Seasonal and locally sourced ingredients, plant-forward menus and accurate ordering can all help reduce an event’s footprint without compromising the delegate experience. Then there’s the question of what happens to anything left over.
We work with Olio to help redistribute suitable surplus food rather than allowing it to go to waste. It’s a simple example of looking at the whole lifecycle of an event decision – not just what happens while delegates are in the room.
Stop automatically buying new
Signage, lanyards, programmes, exhibition graphics, giveaways…the list soon starts adding up.
Conferences can generate an enormous amount of ‘stuff’, much of which may only be used for a couple of days, so one of the simplest questions we can ask is do we actually need something new?
Digital information can replace some printed materials, while signage and branding can often be designed without dates so they can be reused, existing materials should only be replaced when they genuinely need to be.
We also collect and recycle lanyards onsite and look for ways to give unwanted event materials another life, including offering suitable items through platforms such as Freecycle.
It isn’t necessarily about eliminating physical materials altogether, it’s about becoming much more conscious of what we produce, why we produce it and what happens to it afterwards.
Bring suppliers on the journey
The sustainability of an event isn’t determined by the event organiser alone.
Venues, caterers, production teams, printers, exhibition contractors and countless other suppliers all contribute to its overall impact.
That’s why sustainability should form part of procurement from the beginning. Ask venues and suppliers about their environmental policies, waste management, energy use and sourcing, rather than making decisions solely on price and availability.
At BeaconHouse, we operate a sustainability code of conduct which helps set expectations and ensures the businesses we work with understand the standards and ambitions behind our events.
Rethink the exhibition floor
Exhibitions can be a particularly visible source of waste.
Single-use stands, dated graphics, disposable materials and piles of promotional giveaways can quickly add up.
We work with associations to encourage exhibitors to think differently by promoting reusable stands, discouraging unnecessary giveaways and asking organisations to avoid branding or materials that will immediately become obsolete once the conference finishes. Small changes multiplied across dozens, or even hundreds, of exhibitors can have a significant collective impact.
Think about the legacy you leave behind
The impact of an event doesn’t have to end when the final delegate leaves.
Wherever possible, we look for opportunities for conferences to positively contribute to the places that host them, that might be choosing local suppliers and organising food-bank collections to supporting regional environmental projects.
For our team, that has included investment in biodiversity initiatives such as our kittiwake nesting platform and floating ecosystems. It changes the question from simply “how can we reduce the impact of being here?” to “can this event leave something positive behind?”
Remember that sustainability is about people too
Environmental and social sustainability shouldn’t exist in separate boxes. Our ‘Good Festival Ambition‘ that runs through all strands of TechNExt looks at how we can make events both greener and more inclusive, including through funded tickets, supported meals and accessible event experiences. Considering the wider difference an event can make to people, communities and places alongside its environmental footprint.
A genuinely sustainable conference isn’t simply one that produces less carbon. It should also think carefully about who gets to participate, who benefits and what remains afterwards.
Be open about what you’re doing – and what you’re still working on
Nobody expects an event to be perfect. In fact, making sweeping claims about being ‘green’ or ‘sustainable’ without the evidence to back them up can do more harm than good. Instead, communicate the choices you’ve made, explain why you’ve made them and, importantly, report what happened afterwards.
Measurement gives you somewhere to start and something to improve upon.
That’s exactly why we create carbon reports for our events. They allow us and our clients to see what worked, understand where the greatest impacts remain and make better-informed decisions for the next event.
Progress, not perfection
Associations don’t need to transform every aspect of their conferences at once. Start by understanding your current impact, identify the areas where change could make the biggest difference. Put practical measures in place. Measure what happened. Then ask what you can do better next year.
The aim shouldn’t be to deliver one ‘perfectly sustainable’ conference, it should be to make every event better than the last.
If you’re not sure where to begin, we can help you measure where you are now, identify the opportunities that will make the greatest difference and build sustainability into your event from the very beginning.
