How Small Events Can Create Big Environmental Impact

You care, but where do you start? 

For teams running conferences, summits, and community events, sustainability has become a must in event planning and marketing. 

According to the Bizzabo 2024 Event Sustainability Report, 68% of organisers say sustainability is now a “core planning priority”, yet only 32% feel confident implementing it.   

That’s where many small teams find themselves. Full of purpose, short on bandwidth. 

You want to host sustainable events but aren’t sure how to make it achievable. 

Sustainable event management doesn’t require a dedicated department or a huge budget. It starts with intention and small, consistent steps that add up to long-term impact.

Why events need a sustainability shift 

Events bring people together, but they also leave a footprint. 

Some estimates suggest the global events industry contributes a substantial share of worldwide carbon emissions, largely driven by travel, energy use and materials.   

For a single in-person conference, the average participant’s travel can generate 500–1,500 kg CO₂e for one round trip, more than some people emit in an entire year.   

Common sources of environmental impact include: 

• Travel and transport – often the biggest contributor to emissions.   

• Single-use materials – signage, lanyards, badges, packaging, giveaways.   

• Energy use at venues – lighting, AV, heating and cooling.   

• Food waste – part of a global picture where around one billion meals are wasted every day.   

For small teams, these numbers can feel overwhelming. But they also highlight how much difference thoughtful decisions around travel, waste and suppliers can make over a year of events. 

The small team advantage 

Whether you’re a marketing leader at a university or part of a small in-house events team at a membership organisation, the biggest barrier to sustainable events isn’t money; it’s momentum. 

Small teams can move faster, test ideas, and make decisions without lengthy signoffs. That agility is your greatest strength. 

Example: Education Boutique replaced printed guides with QR-based digital event guides for its roadshow series.  

Start small and build confidence 

It doesn’t need to be a perfect plan. Just a clear first step.

Focus on one goal

Pick a single area to improve. Waste, local sourcing, or energy use. Clear focus makes progress easier.

Be transparent

Share what you’re trying, where you’re learning, and what you’ll improve next time. Audiences value honesty.

Tell your story

Even small wins matter. Simple metrics communicate your values more powerfully than vague claims.

A B2B tech start-up did this well.

Instead of listing “eco-friendly catering” in a bullet point, they shared a short video thanking the local bakery that supplied pastries and explained the partnership.

Engagement tripled because it felt human, not corporate.

The ripple effect

Sustainable event management creates value long after the event ends. It doesn’t just reduce waste, it strengthens your organisation’s reputation and demonstrates leadership in your sector. 

According to NielsenIQ, 78% of global consumers say living sustainably is important to them — and they expect brands to show real, visible action, not just words.

10 Innovative strategies for achieving sustainability in events 

For teams ready to move from inspiration to action, here are ten practical strategies that make sustainable event management achievable whatever your size or budget:

1️⃣ Design for reuse, not Disposal 

Create signage and displays without dates or one-off messaging so they can be reused across multiple events. 

Example: Modular backdrops or magnetic panels that can be re-skinned.   

2️⃣ Go Local at Every Level 

Choose venues, caterers, and suppliers within a short travel radius to cut transport emissions and support local economies. 

Some event roadmaps suggest local procurement alone can drive meaningful cuts in emissions.   

3️⃣ Adopt Circular Catering 

Work with caterers who serve seasonal menus, minimise over-production, compost waste, and donate surplus food through local partners or food rescue apps. 

4️⃣ Integrate Digital Efficiency 

Swap printed programmes, flyers and handouts for QR codes, apps, and digital signage. 

One 200-person event can save thousands of sheets of paper by going fully digital.   

5️⃣ Measure and Offset Carbon 

Use carbon calculators (like TRACE by isla or Net Zero Carbon Events tools) to estimate your event emissions and offset what you can’t avoid.   

6️⃣ Choose Certified Venues 

Look for venues with sustainability credentials such as ISO 20121 or recognised green building ratings, which often include renewable energy use and robust waste systems. 

Tip: To find ISO 20121 or other certified sustainable venues, check databases like the BSI Certificate Directory or the Net Zero Carbon Events network.

7️⃣ Engage Attendees in the Mission 

Invite attendees to participate: clear recycling points, refill stations, no swag by default, or a “one action for the planet” wall. 

Example: Plant a tree or fund a local community project for every feedback form completed — a simple action that connects engagement to real-world impact. 

8️⃣ Build Community Partnerships 

Collaborate with local charities, schools or social enterprises as suppliers or beneficiaries. 

Donate unused materials, decor or equipment so they find a second life.  

Example: Partner with organisations like Event Cycle, which helps event planners find sustainable solutions for surplus materials — redistributing items to charities, schools, and community groups to create a lasting social legacy. 

9️⃣ Rethink Energy Use 

Use LED lighting, time-controlled AV, and venues with renewable energy commitments. 

Industry case studies show that simple operational changes can reduce electricity use significantly.   

🔟 Tell the Sustainability Story 

Share your efforts and results before, during and after the event: “85 kg of waste diverted”, “60% of suppliers local”, “100% digital programmes”. 

Guidance from sustainability bodies like isla emphasises that clear communication builds trust and encourages others to follow.   

These ideas arent about perfection, they’re about progress. Even adopting one or two can make a measurable difference and spark new habits for your next event. 

Sustainable events start with strong organic marketing 

True sustainability applies to how you market your events too.  

Too often, teams rush into paid advertising, chasing quick wins before their organic strategy has had time to mature. But organic marketing, consistent content, authentic engagement and audience trust builds the foundation that paid campaigns can later amplify.  

Start by mastering one or two core channels and making them work well. Focus on clear, value-led content, consistent audience engagement, and evergreen funnels that keep delivering long after the event ends. 

When your organic marketing runs smoothly and efficiently, paid campaigns don’t have to fill the gaps — they simply amplify what’s already working. 

What sustainable event management looks like in practice

Community business showcase: A 100-person local business event donates surplus catering the same day to a nearby shelter and publicly thanks the charity partner in post-event content. 

University networking evening: Reusable pop-up stands and undated signage are designed once and used across multiple events during the academic year. 

Hybrid conference: The event goes paperless, records sessions for replay, and encourages train travel over flights where possible — cutting emissions and extending reach. 

Each example shows sustainability working with strategy, not against it. 

Legacy Starts Here: Every event leaves something behind. Will it be waste or will it be worth remembering? Start small, stay consistent, and let every decision become part of your legacy.
