Sustainable event guide and certification

The Sustainable Event Guide and Certification is intended to help all Concordians host more socially and environmentally sustainable events.

About the guide

The Sustainable Event Guide is meant to help all Concordians host more socially and environmentally sustainable events.  

It was developed by the Office of Sustainability and Hospitality Concordia in collaboration with the Access Centre for Students with Disabilities, the Black Perspectives Office, the Office of Community Engagement, the Equity Office, the Office of Indigenous Directions, and Zero Waste Concordia in Facilities Management. We would also like to thank the Concordia Student Union, the Sustainability Action Fund, and Sustainable Concordia for their valuable contributions.

This guide aims to address aspects of sustainability related to in-person, virtual, and hybrid events. As such, not all sections will be applicable to all events.

The Sustainable Event Guide includes best practices related to:


a. If you have an event planning committee, deliberately integrate underrepresented communities

b. Include and adequately compensate voices of underrepresented communities in your event’s content

c. Promote your event using diverse channels

d. Establish a code of conduct and clarify channels for participants to report violations

e. Encourage speakers and participants to optionally share their pronouns when introducing themselves, and use non-binary language when possible

f. Provide options for childcare

a. If you have an event planning committee, deliberately integrate Indigenous perspectives

b. If your event features content or perspectives related to Indigenous peoples, ensure that you consult with and invite the appropriate voices and provide appropriate compensation

c. Adapt the land acknowledgement available from Indigenous Directions and practice pronunciation beforehand

a. Follow basic best practices for universal accessibility (e.g. automatic closed captioning enabled, option to participate via microphone or text chat, anonymous submission of comments or questions for virtual events; accessible venue, description of accessibility fatures, clear signage, event greeters for in-person events)

b. Enable accessibility accommodations for those who request it (e.g. note-takers, advance copies of audiovisual materials, captioning services, sign language interpretation services, personal attendant)  

c. Ensure web pages, documents, presentation materials, and promotional material follow accessibility guidelines

d. Make your event financially accessible by offering it for free or enabling reduced pricing

e. Hold your event at an accessible time for your audience

f. Encourage your facilitator, moderator, or event host to use accessible and anti-oppressive facilitation styles

g. If offering an all-day or multi-day event, include adequate breaks and wellness activities in your program

h. After your event is over, make event materials accessible

i. Collect feedback after the event and record lessons learned

a. Consider reusable options for event promotion and signage

b. Favour reusable dishware over disposable

c. Reduce single-use packaging and select eco-responsible packaging options

d. Provide sorting bins for waste management

e. Donate leftover food

f. Follow basic best practices for energy saving

g. If your event includes off-campus participants, encourage participants to take sustainable modes of transportation to your event

h. If non-local participants are invited, consider whether they can participate virtually

a. Choose sponsors and suppliers that fulfill at least two of the following criteria: (1) local; (2) operate as a social economy enterprise or are committed to social sustainability; and / or (3) committed to environmental sustainability

b. Purchase from at least one supplier AND / OR catering business owned by underrepresented communities

c. Give non-physical gifts, prizes, and giveaways or, if necessary, choose products that are environmentally and / or socially responsible and which attendees can opt out of

d. Offer an equal number or more plant-based dishes than meat options and no dishes that include beef

e. Prioritize local and / or sustainable food and beverage

a. Invite your participants to reduce their streaming quality and turn off their cameras when not presenting or interacting with others

b. If you are emailing participants, in the signature portion of your email include a reminder to delete emails that are no longer necessary

c. When sending documents and videos to participants, rely on your event platform or use cloud-based sharing

a. Communicate the sustainability measures that are being taken for the event and explain why

b. Communicate actions that participants, speakers and presenters can take during the event to reduce their impact

c. If your in-person event has over 100 participants, or your virtual event spans multiple days or has 500 participants, calculate the GHG emissions associated with organizing and hosting the event

d. If you calculated GHG emissions related to your event, purchase high-quality certified offsets to negate the GHG impact

Why seek certification

The Sustainable Event Certification is a voluntary and free service available to all members of Concordia who wish to take measurable action in making their events more sustainable.

Event organizers get support in selecting and implementing positive actions. Once certified, they can communicate their achievements to raise awareness and gain recognition of their efforts.

To calculate an event’s score, we compare the number of planned actions with those potentially applicable and calculate a percentage.
