Your conference isn’t just creating connections.
It’s also creating carbon — and a lot more than you think.
In-person professional events in Europe — summits, keynotes, networking sessions — can have an eye-watering environmental impact. On average, each attendee generates about 1 tonne of CO₂ emissions just by showing up.
Multiply that by a hundred guests, and you’re looking at over 100 tonnes of CO₂ — the equivalent of needing 5,000 trees working all year just to offset the damage.
Let’s break it down — and show you how you can host better, greener events without sacrificing anything.
📊 The Brutal Numbers: What Your Event Really Costs the Planet
- Each attendee: ~1.0 tCO₂e emitted
- Mid-size event (100–120 attendees): ~100+ tCO₂e
- Equivalent: 5,000 trees absorbing carbon for an entire year
🧠 Reality Check: One average-sized European conference = an entire mini-forest needed to absorb its emissions.
And it’s not just travel (although air travel alone makes up 70%+ of event emissions). It's the printed brochures. The badges. The bloated event apps clogging devices. Every small choice snowballs.
🚨 What’s Driving Your Event’s Carbon Footprint?
- ✈️ Attendee Travel: #1 cause — especially flights
- 🏢 Venue Energy Use: lighting, heating, AV tech
- 🏨 Accommodation: hotel stays and services
- 🥘 Catering Choices: meat-heavy menus = bigger footprints
- 🗑️ Materials and Waste: printed programmes, badges, signage
Bottom line?
Travel is the biggest culprit.
Printed waste comes next.
And bloated tech isn’t far behind.
