Sustainable Event Planning Guide

During Event Execution

Implement the planning stage strategies correctly.

  • Ensure recycling bins are placed strategically so that recycling rates are maximised.

  • Stick to waste management plans - limit resources as planned e.g. printed materials.

  •  Ensure all ground staff and volunteers are well-informed on sustainable strategies to avoid conflicting actions.

Events are not static but dynamic. So observe how waste and resources are being handled by on-site vendors and event-goers. If something is not going according to plan, be open to making changes on the spot, so results are maximised.


Communicate sustainable measures clearly with on-site vendors and event-goers.

  • Have sufficient posters and indicators for what event-goers are supposed to do.

  • Make periodic announcements to remind event-goers on the 3Rs.

  • Ground staff should be pro-active and guide event-goers.

  • OSIM Sundown Marathon 2018 (left) - runners were encouraged to recycle using a few strategies - read case study here.

The “spirit of sustainability” needs to be infused into an event for people to sit up, take notice and put into effect.

  • For fun events, invite mascots who promote sustainability e.g. Sustainable Singapore Movement mascots, as a way to remind people, particularly youngsters, of behaving sustainably.

  • For events that are professional in nature, opt to start off the event with a clear message on the need to be green from the organisation leading the event, or the Guest of Honour, this sets the right tone for the event.

1. Collect data from energy, water, resource use, waste, attendee and vendor engagement etc.

Baseline Data is a useful tool for events that occur annually e.g. marathons, gala dinners, festivals. Year on year improvements can be targeted with achievements shared with stakeholders and event-goers. This serves as an encouragement and sense of accomplishment for everyone involved.

2. Provide live Feedback, if possible.

Provide live feedback to participants if possible. E.g. If your event gave out upcycled door gifts, then share with participants how the gifts were made. This is a form of awareness and education. It also signals that your organisation is aware of environmental impacts and is committed to sustainability.

If your event has opted to replace single use bottled water with water dispensers, let participants know how many plastic bottles were saved because of their cooperation. This recognises their efforts and promotes inclusiveness with a common goal.

“Sustainability is a collective effort and people like to be recognised for their efforts. If your event benefited from stakeholders and event-goers doing their part, share it with them and recognise their efforts.”
