Events can definitely be wasteful. From leftover food to single-use branding, there’s often more going in the bin than anyone would like to admit. But that’s changing, and for good reason. With sustainability front and centre for many businesses, corporate events need to walk the talk when it comes to the environment.

We’ve been helping clients create greener events for years – not because it’s trendy, but because it’s the right thing to do. The good news? You don’t have to overhaul everything overnight. Small, practical steps can make a big difference.

So whether you’re planning a leadership retreat, an annual conference, or a team celebration, here’s how to reduce your event’s environmental impact – without compromising on quality, experience or style.

Rethink Your Venue Choice

Your venue sets the tone for everything else. Choosing a location that takes sustainability seriously is one of the most impactful decisions you’ll make. Look for venues with recognised environmental certifications (like BREEAM or ISO 14001), strong waste management policies, energy-efficient systems and commitments to local sourcing.

It’s also worth considering travel. A centrally located venue with good public transport links makes it easier for guests to arrive without a car – and that can make a meaningful dent in your event’s carbon footprint.

Top tip: Always ask about a venue’s sustainability policy. If they don’t have one, that’s a red flag for us!

Go Digital Where It Counts

We’re not saying you need to ditch all print materials forever, but you can absolutely reduce them. Event apps, QR codes and digital signage are easy, professional ways to cut down on waste while improving the delegate experience.

If you do need printed materials, keep them minimal, use recycled paper, and avoid lamination. You can also design them to be reused for future events by avoiding dates or overly specific branding.

Be Smart with Catering

Food waste is a big contributor to a negative environmental impact at events – and it’s one of the easiest things to change. Here’s how:

  • Choose caterers that use local, seasonal ingredients.
  • Offer plant-based options as standard (not as an afterthought).
  • Avoid over-catering: accurate guest numbers and portion control go a long way.
  • Donate leftovers, if your caterer or venue can facilitate this.
  • Ditch single-use plastics (cups, cutlery, straws) and opt for reusable or compostable alternatives.

And don’t forget to shout about it as guests often appreciate knowing the food choices they’re enjoying are also kind to the planet.

Ditch the Gimmicky Giveaways

How many branded stress balls and keyrings actually make it home? Swag should be useful, desirable, and sustainable – or not exist at all. We always encourage clients to reconsider giveaways unless they genuinely add value.

If you must do delegate gifts, think quality over quantity. Branded notebooks made from recycled materials, refillable water bottles, or donations to a local charity in guests’ names are all great alternatives.

Even better, let people opt-in to receive something rather than handing out items by default.

Offset Travel – But Do It Properly

While reducing travel is best, sometimes it’s unavoidable. That’s where carbon offsetting comes in, but only if done properly. Work with reputable providers who can calculate your event’s emissions and help you support verified offsetting projects.

Encourage train travel over short-haul flights where possible, and consider offering group transport to reduce the number of vehicles on the road.

Bonus: environmentally considerate travel options are often a selling point for attendees and sponsors.

Train Your Team and Suppliers

Everyone involved in your event should know your sustainability goals, from your internal staff to your AV team, caterers and cleaners. Include clear instructions on waste separation, signage policies and setup expectations.

It helps to assign someone as your ‘green lead’ who is the single point of contact to oversee your environmental efforts throughout planning and delivery. Trust us, this makes a huge difference on event day.

Measure and Improve

Sustainability isn’t something you do once, it’s a healthy habit. Gather data where you can: how much waste was recycled? How much food was left over? How many guests used public transport?

Include questions in your post-event feedback about sustainability. People are more likely to notice and value your efforts than you might think.

And don’t forget to use what you learn to improve for next time. Every step forward counts.

Do What You Can, Be Honest About It

We’re big believers in progress over perfection. You don’t have to tick every single box, and you certainly don’t need to compromise on experience. Sustainable corporate events are better for your brand, your audience, and your long-term planning strategy.

We’re always looking for new ways to help our clients build greener, smarter experiences, and we’d love to help you design an event that feels good while doing good!
