Sustainable Conferences: Planning Guide

18 September 2026


In 2026, a few recycling points and a plant wall will not make your conference sustainable.

The real work begins much earlier, when you decide where people will travel from, what needs to be built, how delegates will be fed, and what will happen to everything once the final session finishes.

Sustainable conferences still need to engage an audience, support the organisation’s objectives, and give people a reason to be there. It just does those things with more thought behind the decisions.

AOK Events became a Certified B Corporation in 2026. While we’re incredibly proud of that, it doesn’t mean every event we plan is automatically sustainable or that we’ve reached some kind of finish line. It gives us a framework for accountability, transparency, and continuous improvement, keeping us focused on how each event could be planned more responsibly than the last.

So, if you’re planning a sustainable conference of your own, here’s what you need to know…

 

What Is A Sustainable Conference?

A sustainable conference is designed to reduce its negative impact while leaving something worthwhile behind for the delegates, suppliers, and communities involved.

That might mean choosing an accessible venue, reducing unnecessary travel, serving more plant-based food, hiring rather than purchasing materials, preventing waste, and working with local suppliers.

The important part is when those decisions are made. Sustainability works best when it’s built into the original brief, not added once the venue, menu, production, and travel have already been booked.

It should also be measured where possible. Without a starting point or post-event data, it’s difficult to know which choices made a difference and what should change next time.

 

Why Are Sustainable Conferences Important?

Conferences can bring hundreds or thousands of people together, creating valuable conversations, partnerships, and ideas. It also means their impact can add up quickly.

Delegate travel, venue energy, accommodation, catering, freight, production, temporary branding, and waste all contribute. Even the most responsibly operated venue can only do so much if the rest of the event hasn’t been planned with the same attention.

A more sustainable approach can reduce waste, make better use of the budget, support responsible suppliers, and ensure the experience reflects the values an organisation communicates elsewhere.

 

What Makes A Conference More Sustainable?

Start with the impact, not the eco extras

Before deciding whether the lanyards should be made from recycled fabric, look at the larger decisions.

Where are delegates travelling from? Does everyone need to attend in person? Can the venue be reached by public transport? What needs to be built, and which elements could be hired, reused, donated, or avoided altogether?

Agreeing the priorities at the beginning allows them to shape the venue search, suppliers, production, and budget. It also establishes which information should be collected for post-event reporting.

Choose the destination and venue together

The venue may have excellent environmental credentials, but its location still matters.

A venue close to major rail and public transport connections can reduce the need for taxis, coaches, domestic flights, or additional accommodation. For a residential conference, keeping bedrooms, meetings, dining, and evening activities in one place can also limit transfers.

Ask venues for evidence behind their sustainability claims, including information on energy, carbon reduction, waste, water, food sourcing, accessibility, and supplier policies.

B Corp Certification can be a helpful indicator of wider social and environmental performance. However, booking a B Corp venue doesn’t automatically make the conference sustainable. The choices made within it still count.

Make travel part of the plan

Travel can be one of the largest contributors to a conference’s footprint, especially when delegates are arriving internationally.

Choose rail-connected destinations where possible and share useful public transport information from the beginning. Group rail bookings and shared transfers can also make lower-impact options easier.

Hybrid access may reduce unnecessary travel for international delegates, remote speakers, or people attending one part of the programme. It still needs well-planned production, though. A camera pointing at the stage for eight hours is technically a livestream, but it isn’t much of an experience.

Design the event for reuse

Conference sets, signs, exhibition stands, furniture, florals, and delegate materials should all have a plan beyond one day.

Hiring is often the best place to start. Modular staging, adaptable furniture, digital signage, and undated branding can all be used again. If something needs to be made, consider whether it can be stored, repurposed, separated, or donated afterwards.

For conferences held across different countries, local production partners can also reduce the distance people and materials need to travel.

Rethink the conference menu

A more sustainable menu doesn’t need to have guests eyeing up a fast-food stop on the way home.

Plant-forward dishes can be made the default, with meat available by request where appropriate. Seasonal ingredients, accurate guest numbers, thoughtful portions, and a clear food-surplus process can all reduce waste without making the menu feel restricted.

Water refill points and reusable serviceware also remove the need for rows of single-use bottles and cups.

Give delegates less stuff, but more value

Not every delegate needs another tote bag, notebook, pen, water bottle, and branded object to carry home.

If a giveaway serves a genuine purpose and will be used, it can still earn its place. Otherwise, the budget may be better spent on stronger content, a useful experience, or a local social initiative.

Digital agendas and event platforms can reduce printing, although accessibility and delegate preferences should still be considered.

Think beyond the environmental impact

Responsible conference planning isn’t only about carbon and waste. It should also consider who can access the event, who is represented on its stages, and where its budget is being spent.

Captioning, inclusive menus, quiet spaces, representative speakers, realistic breaks, accessible venues, and clear pre-event information can all make it easier for more people to take part properly.

Working with local suppliers, social enterprises, charities, and community organisations can also keep more of the event’s value within the communities supporting it.

This wider view matters to us as a B Corp. An event can’t really be called sustainable if it doesn’t also work for the people attending it.

Deborah Meaden: Where sustainability meets business

Deborah Meaden doesn’t treat sustainability as a worthy side conversation. For her, it belongs within discussions about investment, innovation, leadership, and how businesses prepare for the future.

Known as an investor on Dragons’ Den, Deborah brings commercial experience to a subject that can otherwise become theoretical. She’s also a longstanding advocate for ethical business and co-hosted The Big Green Money Show.

She suits leadership conferences where the audience needs to see sustainability as a business priority, not another commitment sitting in the annual report.

Dr Mya-Rose Craig: Bringing more voices into the conversation

Dr Mya-Rose Craig asks not only what is changing, but who is most affected and whose voices are still missing.

Also known as Birdgirl, the British-Bangladeshi ornithologist and environmental campaigner connects climate change and biodiversity loss with climate justice, diversity, and access to nature.

Mya-Rose is a thoughtful choice for conferences exploring sustainability through a wider social lens, reminding audiences that environmental progress should include the people and communities living with its consequences.

How Do You Measure The Impact Of A Conference?

Impact measurement can sound technical, but the purpose is simple. It’s about understanding where the event had its greatest effect so the next one can be planned better.

That might involve delegate travel, accommodation, venue energy, catering, freight, production materials, waste, and supplier activity. Agreeing what needs to be collected before the event also saves a great deal of chasing suppliers once it’s over.

We work with third-party specialists because proper measurement requires expertise. Positive Planet supports carbon measurement and reduction planning, while Event Cycle finds new homes for surplus materials through charities, schools, community groups, and social enterprises.

A post-event report should explain what worked, where the greatest impacts came from, and what needs to change next time.

Reduction should always come first. Carbon balancing or offsetting should address emissions that remain after realistic steps have been taken to avoid and reduce them.

 

How We’ve Planned More Sustainable Conferences

LinkedIn Future Of Growth Summit

For LinkedIn’s Future of Growth Summit, the brief was to create a hybrid conference for clients attending in London and through VR headsets across EMEA and LATAM.

We selected a central Shoreditch venue and created a remote experience that allowed more delegates to participate without travelling. Vegetarian catering was offered by default, with guests able to request meat when submitting their dietary requirements. Most kept the vegetarian option.

Production included seeded paper, PVC-free vinyl, recycled materials, minimal printing, and a no-plastic policy. More than 60 plants were redistributed to schools and community organisations, while Event Cycle collected surplus materials for reuse.

Invesco Conferences In London And Frankfurt

When Invesco planned corresponding conferences in London and Frankfurt, the events needed to feel consistent without recreating and transporting every element between countries.

We reused an existing exhibition stand, brought reusable shelving into the design, and sourced local production support in Frankfurt. Caterers worked with local produce, while the London menu included low-waste bowl food that made use of ingredients already available.

Delegate badges were recyclable and printed on site, avoiding unused pre-printed badges when the guest list inevitably changed.

Together, these decisions reduced unnecessary materials, transport, and waste while giving both events a consistent identity.

Sustainable Conference FAQs

How can you make a conference more sustainable?

Begin with the decisions likely to have the greatest impact, including the destination, delegate travel, venue, catering, production, and event materials. Set clear priorities, work with suppliers that can evidence their practices, and decide from the beginning how the results will be measured.

Is a hybrid conference more sustainable?

A hybrid conference can reduce travel by allowing some speakers and delegates to join remotely, but it isn’t automatically sustainable. Technology, equipment, data use, and production still have an impact. The format should be chosen according to the audience, content, and travel that can genuinely be avoided.

Does B Corp Certification mean a company is completely sustainable?

Unfortunately, it’s not that simple. B Corp Certification assesses a company’s social and environmental impact, accountability, and governance, but it doesn’t mean the business is perfect or has no negative impact.

For AOK Events, it represents progress and a commitment to keep measuring, reviewing, and improving how we work.

 

Plan Your Sustainable Conference With AOK Events

We won’t promise you a conference with no impact at all. Events use energy, move people, require materials, and create waste. What we can do is question each decision, reduce what we reasonably can, measure the result, and use what we learn to make the next event better.

AOK Events can manage the complete process, including venue finding, delegate travel, registration, production, catering, speaker sourcing, supplier management, impact measurement, and post-event reporting.

Whether you’re planning a one-day conference in London, a residential leadership gathering, or an international summit, we’ll help you deliver what the event needs without treating sustainability as an afterthought.
