Environmental Impact
Events use resources from activities such as venue construction, energy use and transport of spectators and participants, which in turn impact on major environmental issues such as climate change and the reduction in natural resources.
But also, given the significant media attention associated with events, there are opportunities for events to demonstrate leadership of environmental best practice and standards, such as waste recycling, which may be adopted more widely by individuals and organisations after the event.
Decisions made at the early planning stage can significantly influence the types of environmental impacts that arise from the event.

UNDERSTANDING EVENT IMPACT DATA:
Benchmarking for Better Insights
Interpreting event impact data to determine whether a study result is favourable can be challenging, especially without access to historical event data or comparisons from similar events. Our consultants have created a benchmark database to help clients contextualise and better understand their impact study results.
An example of metric used in assessing the environmental sustainability of the event, is the percentage of spectators using public or sustainable transport (ASOIF Reference Code: EN-T2.1).
Ensuring that attendees can access your venue using environmentally friendly options not only helps reduce the event’s carbon footprint but also demonstrates a commitment to sustainability. After analysing over 20 event impact studies, we have found that the percentage of spectators using public or sustainable transport ranged between 32% and 82%.

We have identified several key factors that influence public or sustainable transport use at events and gathered the following advice to minimise negative environmental impact:
- Event Type: International events often generate a higher carbon footprint due to unavoidable travel, therefore focus on local transport options for attendees once they arrive. For more local or regional events, prioritise accessible and eco-friendly travel options.
- Public Transport Availability: Choose venues with good public transport links or, where connections are limited, provide shuttles to help attendees access the venue more sustainably.
- Clear Communication: Inform attendees about sustainable transport options through emails, websites, and social media. Share maps, schedules, and promotions to make eco-friendly travel easier.
- Encouragement Measures: Offer incentives like discounts or priority entry for using public transport, cycling, or carpooling. Discourage single-occupancy vehicle use with limited parking or higher fees.
- Local Reliance on Cars: In more car-dependent areas promote car sharing, which can boost sustainable travel by up to 20%. Provide platforms to connect attendees for carpooling.
By selecting accessible venues, sharing information, and offering incentives, event organisers can promote sustainable travel and reduce their event’s carbon footprint.
