If you ask most people about the environmental impact of events, they think of waste: plastic cups, discarded tents, food packaging. But for the vast majority of UK events, the single largest source of carbon emissions is not on the event site at all -- it is how attendees get there and back. Research by Julie's Bicycle, the leading environmental charity for the creative industries, has consistently found that audience travel accounts for 70-80% of a typical UK event's total carbon footprint. Addressing event sustainability without addressing transport is like bailing water while ignoring the hole in the boat.
The scale of the problem
The maths is sobering. A festival attracting 50,000 people, with an average round trip of 200 miles per attendee and most travelling by car with 2-3 occupants, generates thousands of tonnes of CO2 from travel alone. Even a 2,000-person venue show in a city, where most people drive or take taxis, generates significant transport emissions.
The challenge is that event transport is a classic collective action problem. No individual attendee's travel choice makes a meaningful difference, so there is little personal incentive to choose the inconvenient but lower-carbon option. And organisers, while they can influence travel choices, ultimately cannot control how their audience gets to and from the event.
What is working today
Several approaches to reducing event transport emissions have proven effective in the UK, though none has solved the problem entirely.
Dedicated coach services. Festival coach services, where dedicated buses run from major cities directly to the event site, have been one of the most successful transport interventions. Big Green Coach, for example, serves dozens of UK festivals and significantly reduces per-person emissions compared to car travel. The key to uptake is making coaches affordable, convenient, and well-timed -- a coach that leaves immediately after the headliner and drops you close to home is much more appealing than a generic bus service.
Rail partnerships. Some festivals partner with rail operators to offer combined ticket-and-train packages. These reduce the perceived cost of rail travel and simplify logistics. Festivals with nearby rail stations -- like Latitude (Darsham) or Green Man (Abergavenny) -- are particularly well positioned for this approach. The challenge is that many festival sites are in rural areas poorly served by rail.
Car-sharing incentives. Events that offer discounted parking or preferred parking locations for cars with four or more occupants have seen some success in increasing car occupancy rates. The sustainable travel guide approach works best when the incentive is tangible and visible, and when the car-sharing platform is integrated into the ticket purchase process.
Cycling infrastructure. For urban events and those in cycling-friendly locations, providing secure bike parking, cycle routes, and even cycle-powered phone charging stations can encourage two-wheeled attendance. The Bicycle Film Festival and some London venue events have successfully encouraged cycling attendance.
Electric vehicles: help is coming, but slowly
The UK government's ban on new petrol and diesel car sales, planned for 2035, will eventually reduce the carbon intensity of car travel to events. As the UK's electric vehicle fleet grows, the per-mile emissions of car travel will fall, though they will not reach zero because of the carbon intensity of electricity generation and vehicle manufacturing.
For event organisers, the practical implication is that providing EV charging infrastructure at event sites is becoming increasingly important. Attendees driving electric vehicles will need to charge during multi-day events, and the absence of charging facilities could deter EV owners from attending. Some festivals have already installed temporary charging points, though the power requirements are significant and need careful planning.
It would be a mistake to treat EVs as a complete solution to event transport emissions. Even with a fully electric vehicle fleet, the energy required for thousands of cars to travel hundreds of miles to a field is substantial. Reducing the number of vehicles through better public transport, car-sharing, and modal shift remains essential alongside electrification.
Site selection and accessibility
One of the most impactful decisions an event organiser makes regarding transport emissions happens long before any ticket is sold: where to hold the event. Sites with good public transport links, near population centres, and accessible by multiple transport modes will always generate lower transport emissions than remote rural sites accessible only by car.
This creates a tension with the festival tradition of rural, escapist locations. Part of the appeal of many UK festivals is the sense of getting away from the city, which inherently requires travel. Some organisers are addressing this by choosing semi-rural locations with reasonable public transport connections -- close enough to a city for coach and rail access, but far enough to feel like a genuine escape.
Demand for transparent carbon measurement
Audiences are increasingly expecting events to be transparent about their environmental impact, including transport. Some festivals now publish transport emission estimates and encourage attendees to offset their travel carbon through verified schemes. Others provide transport carbon calculators on their websites, allowing attendees to see the impact of different travel choices.
This transparency serves multiple purposes: it raises awareness, it creates social pressure toward lower-carbon travel choices, and it demonstrates that the organiser takes environmental responsibility seriously. Events that measure and publish their carbon footprint openly tend to attract environmentally conscious audiences who are more likely to choose sustainable travel options.
The last-mile problem
Even when attendees use public transport for the main journey, the "last mile" between the station or coach stop and the event site often involves taxis, private cars, or long walks with heavy luggage. Solving this last-mile problem -- through shuttle buses, cycle hire, or pedestrian-friendly routes -- is essential for making public transport a genuinely attractive option for events.
Some festivals have invested in free shuttle services from nearby train stations, running at regular intervals throughout arrival and departure periods. The cost of these services is significant but can be offset by reduced demand for car parking infrastructure, which is itself expensive to provide and manage.

Looking ahead
The future of event transport is not about a single solution but about making every option lower-carbon and more convenient. Better coach services, rail partnerships, car-sharing platforms, EV infrastructure, cycling facilities, and last-mile connections -- combined with transparent measurement and genuine incentives -- can collectively reduce the enormous transport footprint of UK events. The technology and business models exist. What is needed is the will to implement them at scale and the honesty to acknowledge that transport is the biggest environmental challenge the events industry faces.
