Most events leave a pile of lanyards, banners, and single-use giveaways in the bin by the time the doors close. If you are planning one and want it to leave something better behind, the real questions are practical: what do you actually change, and how do you show attendees it was real rather than a label on the programme?
A green event is a gathering planned to lower its environmental impact through choices like waste reduction, lower-emission travel, and planting trees that contribute to verified reforestation. Planting trees at an event is one of the clearest of these actions: ForestNation pioneered planting a tree for every purchase back in 2006, and the same model lets organisers plant a verified tree in Tanzania for every attendee, ticket, or lead. If you want planting as your green activity, you can plant trees at your event with no minimum size and global delivery for in-person and virtual events.
Each tree is field-measured at about 0.025 tonnes of CO2 per tree per year (25kg, with a 30 percent uncertainty discount applied) by ForestNation’s Working Trees field study across five Tanzania sites, so your event’s contribution is a measured figure rather than an estimate. For corporate programmes that run across many events, see how to plant trees for corporate events, and for cutting event waste alongside planting, see this guide to zero-waste events.
Key Takeaways
- A green event lowers its environmental impact through waste reduction, lower-emission travel, and tree planting that contributes to verified reforestation in Tanzania.
- Planting a verified tree for every attendee, ticket, or lead turns a one-off event into a measured contribution to forest restoration that you can report with confidence.
- Each tree is field-measured at about 0.025 tonnes (25kg) of CO2 per tree per year, with a 30 percent uncertainty discount applied, across five Tanzania sites.
- ForestNation pioneered planting a tree for every purchase in 2006, and now lets event organisers plant trees at their event with no minimum size and global digital delivery.
How do trees make an event greener?
Here are 6 unique ideas for making your events green and memorable by planting and gifting trees.
1. Tree Kits as Event Giveaways
Make a lasting impression by giving away tree kits that attendees can grow at home. The kits are plastic-free and compostable, and every kit funds a verified tree planted in Tanzania, so the takeaway contributes to forest restoration instead of going in the bin.
To brand the giveaway with your logo and message, order custom branded tree kits for your event.
Plant matching trees to add a powerful cause message and create more positive impact.
Encourage recipients to share their growth journey by naming their trees and posting photos and updates.

2. Tree Kits as Event Passes
Say goodbye to plastic and hello to plastic-free tree kits as your event passes.
Not only will attendees appreciate your sustainable efforts, but the trees they grow will serve as a lasting reminder of your event’s impact
Take it a step further by choosing bamboo lanyards for a completely plastic-free solution.
3. Plant trees with any Gift
Make your gifts more meaningful by adding a green touch. For each gift, plant a verified tree in Tanzania so the gift carries a real contribution to reforestation. Highlight this on the product’s packaging or inserts, and include a QR code that leads to your Forest Profile. Recipients can see their contribution and plant more trees with you.
4. Gift a Forest to Event attendees
Gift event attendees a Forest that contributes to verified reforestation in their name. Plant trees on their behalf and send them an eGift with a personal message. They can view their gifted Forest and your message in their Forest Profile instantly.

5. Plant Trees to Contribute Toward Your Event’s Footprint
Measure your event footprint, then plant verified trees as a meaningful contribution toward it. There are several event footprint calculators available online to help you estimate your event’s impact before you plant.
Here’s a great example from ME Week on how to communicate an event sustainability story credibly.
6. Lead Gen at Events with Trees
Use QR codes and landing pages with lead capture forms at events. For every form filled out, a tree is planted. Attendees receive an email with their gifted forest and a personalized message from you.
ForestNation is offering this Lead Gen tool to Event exhibitors and organizers for free – we will plant 1 tree for free for every new lead you generate.
Bonus: ForestNation Gift Stories for Event Participants
The most memorable green event freebie: a ForestNation Gift Story for each participant. A real tree planted in their name in Tanzania, delivered by email during or after the event, with a personalised message and a Forest Profile they can visit and share. No logistics, no packaging, no address collection. For event tree gifting programmes: set up an event tree gifting programme.

Green events, also known as sustainable events, are gatherings organized with an aim to minimize environmental impact. They incorporate strategies like waste reduction, energy efficiency, and lower-impact materials in place of single-use giveaways. Green events emphasize on environmental responsibility at every stage of the event planning and execution, striving to leave a positive imprint on our planet.
Green event ideas can range from choosing a sustainable venue, implementing an effective recycling policy, to giving attendees tree kits from ForestNation which serves as an eco-friendly event participation souvenir. Other ideas can include arranging for shuttles for transport to reduce carbon emissions, promoting carpooling and public transit among attendees, and choosing caterers who provide locally-sourced, organic food to minimize carbon footprint.
A comprehensive guide to green events should include an understanding about sustainable event management, with focus on waste stream knowledge and identification of areas needing improvement. The guide should provide practical ways to make events sustainable, such as the usage of digital invitations, promotion of recycling and upcycling, opting for green catering, and incorporating eco-friendly promotional products. Additionally, it should also dwell upon steps to reduce and balance carbon emissions, collaborations with sustainable event suppliers and ways to educate attendees about sustainability.
In 2026, we envision green events to become mainstream, with increased digitalization, use of sustainable materials and an emphasis on carbon reduction. We hope to see a surge in the use of ForestNation’s tree kits as giveaways, contributing to long term sustainability and giving attendees a powerful reminder about the significance of eco-friendly practices. Also, in line with global trends, we anticipate that more events will incorporate innovative green technology, actively promote sustainable transportation options, and place greater importance on educating attendees about their role in protecting our environment.
