Conferences bring people together to share ideas, build connections, and inspire change. But they also generate a lot of waste - from single-use plastics and paper programs to carbon-heavy travel. For event planners, the challenge is clear: how do you create an unforgettable experience while reducing environmental impact?

The good news? Sustainable, eco-friendly conferences are no longer out of reach. With the right strategies and products, you can minimise waste, save money, and boost your event’s reputation. In this guide, we’ll explore what makes a conference eco-friendly, why sustainability matters, and seven proven ideas you can put into practice today.

An eco-friendly conference is one designed to reduce negative impacts on the environment while still meeting attendees and organisers needs. This often involves minimising waste, choosing sustainable venues, encouraging greener travel, and using eco-conscious event products.
The goal isn’t perfection - it’s progress. Even small changes across a 500 or 5,000-person conference can make a measurable difference.

7 Sustainability Ideas for Conferences

Here are seven practical steps you can take to make your next conference greener:

1- Choose UK certified green venues
Your venue is the single biggest factor in making your conference eco-friendly. In the UK, look for venues with recognised sustainability certifications such as:

  • BREEAM (Building Research Establishment Environmental Assessment Method) – the UK’s leading environmental assessment for buildings.
  • ISO 20121 – the international standard for sustainable event management, widely adopted by UK venues.
  • Green Tourism Award – a UK certification recognising eco-friendly hospitality and venues.

When shortlisting venues, also consider accessibility. Choosing locations near public transport links (rail, underground, bus) or within walking distance of hotels reduces the carbon impact of attendee travel—particularly important in cities like London, Birmingham, and Manchester

2- Go Paperless with Digital Tools
Cut down on unnecessary printing by:

  • Creating digital agendas and schedules accessible via QR codes
  • Using mobile event apps
  • Replacing printed signage with screens or digital kiosks

Not only is this eco-friendly, but it also gives attendees real-time updates and reduces print costs.

3- Switch to eco-friendly event products
Every attendee interacts with items like wristbands, lanyards, and passes. Choosing sustainable alternatives makes a visible difference. ID&C offers a full eco-friendly product range designed for conferences, including:

Recycled PET Fabric Wristbands - made from recycled plastic bottles, durable for multi-day use, and fully customisable.

Eco-Friendly Lanyards - available in recycled PET or biodegradable bamboo, both comfortable, durable, and customisable with branding.
Recyclable Event Badge - waterproof and printed in a CO₂-neutral press, perfect for multi-day conferences.
Paper Event Passes - budget-friendly, printed on card with eco lamination, ideal for single-day conferences.

These products maintain the same level of security and professionalism as standard options, while supporting your sustainability goals.

4- Serve Sustainable Catering
Food is often one of the largest contributors to event waste. Sustainable strategies include:

  • Offering more plant-based and locally sourced meals
  • Avoiding excess by planning menus based on accurate headcounts
  • Donating surplus food to local charities

Attendees notice and appreciate eco-conscious catering choices.

5 -Minimise single-use plastics
Eliminate disposable cups, plates, and cutlery by switching to compostable or reusable tableware with water refill stations instead of bottled water. This reduces plastic waste dramatically, while aligning with eco-conscious attendee expectations.

6 - Encourage sustainable travel
Transportation often makes up the largest share of an event’s carbon footprint. Reduce it by:

  • Organising shuttle buses from hotels
  • Providing incentives for public transport or carpooling
  • Offering hybrid/virtual attendance options for those unable to travel

These steps reduce emissions and demonstrate your commitment to sustainability.

7 - Promote Recycling and Donation Programmes
Set up clearly labelled recycling and compost bins throughout your venue, and encourage attendees to use them. Use our recycling scheme, where you send back the leftover accreditation and we handle the recycling. Go one step further by donating leftover signage, passes, or merchandise to schools or charities.

This not only reduces landfill waste but also gives back to the community.
