Tree Trust


Tree Trust is a made in Centre Wellington solution to help offset the carbon generated by air travel.

Tree Trust is like other offset programs as we plant strong and resilient trees in your neighbourhood. In addition to tree planting, Tree Trust funds will be invested to hire professional arborists, including members of the newly formed Centre Wellington Arborist Association to look after large old trees in our community. By extending the life of these large mature trees we are securing the carbon they have already captured until younger trees are mature enough to grow into their role as carbon capture heroes. Of course, we also know that keeping trees alive and well also supports the many other economic, social and environments benefits that big trees provide. Using Tree Trust is easy. Use our simple calculator below to enter the distance you have flown. Based on global best practices, we will calculate your portion of carbon produced on your flight and what investment in our local tree economy will offset that carbon. Investing through Tree Trust is surprisingly inexpensive: a return flight from Toronto to Vancouver requires only $36. A trip from Toronto to Amsterdam is just $26.

Tree Trust is brought to you by the Elora Environmental Centre. In addition to being local, we have the most local carbon offset plan going! As a social enterprise, we don’t charge HST and all payments to Tree Trust receive a tax receipt. In one simple step you can reduce your environmental footprint!

Happy travelling and thanks for helping grow–and maintain–our local tree economy.

Q: How does an offset program work?
Air travel emits a great deal of green house gas. By planting and maintaining trees we hope to absorb and retain enough CO2 to “offset” your share of what was emitted during your flight. Trees are great at sequestering carbon from the air and need to stay healthy to keep working for us. That is why plants new trees and maintains legacy trees.


Q: How does your calculator estimate the carbon output from a flight?
The ECE looked at several carbon calculators used by airlines and environmental organizations to determine how much CO2 is emitted per passenger on a flight. Based on this research we have chosen a carbon emission number that takes into account many of variables and factors associated with air travel. For example, planes use extra fuel to take off and reach altitude, so longer flights will use a bit less and shorter flights a bit more than the calculated amount.

Our calculator is easy to use. Simply enter the duration of your flight, number of travellers and whether it is one-way or a return trip, and based on that rate, the Tree Trust calculators approximates your portion of the plane’s emissions.


Q: Where will trees be planted?
Our new trees will be planted close to the legacy trees we are caring for. This will let our larger trees protect and nurture the younger trees as they grow into fully grown carbon capture heroes!


Q: What existing trees will you care for?
Large trees often have structural issues such as dead and broken limbs. They also benefit from a professional crown reduction to reduce stress or trimming off limbs that are at risk of breaking. In the hands of our professional arborists these regular maintenance issues are looked after quickly and easily!

We choose trees in our community that are in need of this support based on recommendations from local arborists and our network of tree supporters.


Q: Can I set off my driving or home heating?
At this time, Tree Trust is offering an offset solution for flights. Sign up for the Elora Environment Centre newsletter by emailing and we will keep you posted about any additions to our program.


Q: How is this different from other offset programs?
In addition to planting new trees, Tree Trust uses our funds to look after large old trees in our community. By extending the life of these large mature trees we are securing the carbon they have already captured until the young trees we have planted are mature enough to grow into their role as carbon capture heroes.


Q: Can I offset my carbon from past trips?
You sure can! Follow this link and pledge to support ¼ or ½ of the costs associated with a complete professional legacy tree trim. With a contribution of $200 or $400 we will send you a picture of tree that you have helped

Tree Trust Launch

We were pleased to launch our carbon offset program this weekend! Saturday, #TreeTrust saw its first legacy tree cared for by Baum Tree Care, Full Circle Tree Care, MW Tree Service, and Out of Your Tree Care. We would also like to thank our MP Michael Chong, Wellington-Halton Hills for showing support, and Al Koop and Gary Bryant, for sharing the history of the site. People wishing to make up for the carbon cost of past flights can purchase retroactive offsets. With a minimum $200 purchase, you adopt 1/4 of the tree and receive its picture and a certificate. Jason Thompson was the first to take us up on this offer, with a donation reflecting 1/5 of his plane ticket price. Under the legacy tree, two sugar maples donated by Green Legacy were planted by volunteers led by Urban Forest Manager Mat Alain.

The launch capped off with a tree walk, lead by the irrepressible, entertaining, and knowledgeable Rob Guthrie.
