GreenFleet plants trees to help offset vehicle emissions based on on how many vehicles you have, how big they are and how far they are driven each year. For more information on tree planting click here. To Join GreenFleet, click the button below.

Treeplanting Information
GreenFleet members and supporters planted over 10,000 trees in 2007 and 17,000 in 2008.
How many trees do you need to plant to offset the emissions from a car?
To offset the emissions of a typical medium sized vehicle on the road in New Zealand, you need to plant 23 trees per vehicle per year that the vehicle is on the road. This average figure was calculated based on a petrol engine vehicle travelling 15,000km per year, with a fuel economy of 10 litres / 100 km. This motoring will produce 3450kg of carbon dioxide emissions.
How does GreenFleet calculate how many trees to plant?
Native trees remove from the atmosphere approximately 2.5 tC/ha/yr (on average), accumulating a maximum stock of around 500 tC/hectare for some forest types. In addition, the quantity of 23 trees per vehicle per year builds in a 10% mortality rate as a safety net for successful plantings.
How much does it cost?
It depends on how big your vehicle is and how far it is driven annually.

Can GreenFleet members plant their own trees?
Absolutely. We encourage Greenfleet members to get out of the office and participate in planting their trees and make the most of this opportunity to enjoy a fun day and learn more about their local community and heritage. Many members find this to be a great team building exercise and good way to build connections with their community.
Where do all these trees go?
The trees are planted at sites chosen by local planting and restoration organisations.
The sites where planting has taken place and their corresponding planting groups are:
- Oakley Creek Walkway, Auckland. Friends of Oakley Creek. 2006, 2007, 2008, 2009.
- Whau Creek, Auckland, Blockhouse Bay Intermediate School. 2004, 2006, 2007, 2008, 2009.

Who supervises the planting?
The planting groups GreenFleet partners with are required to work under the guidance of the local or regional council. This is to ensure that planting groups work to an agreed planting plan and in line with council planting guidelines.
What about on going monitoring?
Planting groups are required to monitor planting for the first two years to ensure that there aren't losses greater than the 10% allowed for.
What type of trees are planted?
All planting funded by GreenFleet is for native species. The actual species planted at each site differs according to the requirements defined in the planting groups own planting plan as suitable for the location.
Where do the trees come from and who provides them?
The trees we plant come from 3 sources. For planting done in partnership with Trees for Survival (TFS) the seedlings are grown by the participating schools in specially developed potting units provided by TFS. Most planting done in co-operation with local restoration groups are made using trees grown in commercial or council owned nurseries. A few restoration groups grow their own seedlings.
What about carbon credits?
Whilst having an offset effect, trees planted through GreenFleet do not incur a carbon credit. The costs associated with planting are deemed to be a donation to the restoration group.
