Why Sustainability Ambassadors Should Be at the Forefront of Events

Sustainability plans can look brilliant on paper. Reusable cups. Clearly labelled recycling streams. Sustainable travel initiatives. Waste reduction targets. But whether you're welcoming thousands of people to a festival, sporting event, stadium or mass participation race, somebody still needs to help make those plans work once the gates open. That's where Sustainability Ambassadors come in. As the events industry continues to reduce its environmental impact, we believe dedicated sustainability staff should become a familiar part of event teams — bridging the gap between an organiser's sustainability strategy and what actually happens on the ground.

One of the biggest advantages of Sustainability Ambassadors is simple: they're there.

Signage can tell somebody which bin to use, but a friendly person standing beside a recycling point can answer questions, encourage correct waste separation and explain why the system works the way it does.

At Massive Attack x ACT 1.5 in Bristol, our Sustainability Ambassadors looked after recycling points across an event specifically designed to demonstrate a lower-carbon approach to live music.

ACT 1.5 grew from Massive Attack's collaboration with the Tyndall Centre for Climate Change Research, putting years of research into practice at a major outdoor show.

Our role was one small part of a much bigger sustainability strategy — but that's precisely the point.

Big ambitions rely on lots of smaller actions working properly.

And Sustainability Ambassadors aren't just for music festivals.

Think about the footprint of a major sporting event: thousands of participants and spectators moving around a site, food and drink packaging, hydration points, temporary infrastructure and significant volumes of waste generated within a relatively short period.

At The Big Half in London, our Sustainability Ambassadors were positioned around Greenwich Park, helping participants and spectators use recycling points correctly.

It's a relatively simple intervention, but at a mass participation event, thousands of individual decisions quickly add up.

The same principle applies across marathons, challenge events, stadiums and large outdoor sporting events. If organisers are investing in recycling infrastructure and waste-management systems, having visible people there to encourage correct use can help those systems work as intended.

The best sustainability initiatives often require audiences to actively participate.

That might mean separating waste correctly at a sporting event, returning a reusable cup at a festival, using a deposit scheme or simply understanding why an organiser has introduced a particular initiative.

At Sonic Boom Festival, our Sustainability Ambassadors supported a cup deposit system trial, helping audiences understand the process and encouraging cups back into the system.

Different events require different approaches, but the principle remains the same:

make sustainable choices easy, visible and approachable.

A good Sustainability Ambassador isn't there to lecture people. They're there to help.

Waste streams only work effectively if the right materials actually reach them.

Reusable systems only work if products come back.

And sustainability initiatives are much easier to engage with when people understand what they're being asked to do.

Dedicated sustainability staff can also provide valuable feedback from the event floor. If hundreds of attendees are confused by the same recycling point or repeatedly asking the same question, that's useful information for organisers.

It creates an opportunity to learn, adapt and make the system better next time.
