A carbon offset represents the prevention, reduction, or removal of 1 tonne of carbon dioxide equivalent (tCO2e) from the atmosphere. Offsetting carbon allows us to compensate for the unavoidable carbon emissions generated in everyday life.
At Carbon Positive Australia, we generate carbon offsets by planting native vegetation on degraded farmland. This is part of a range of nature-based solutions to combat climate change.
Every carbon offset you purchase helps us plant more trees and shrubs, restoring the natural landscape and biodiversity of our amazing continent.
Trees remove or ‘sequester’ carbon dioxide from the atmosphere and convert it into organic carbon as they grow – storing it in their trunks, stems, leaves and roots. Approximately half the dry weight of a tree’s biomass is carbon.
The amount of carbon sequestered per hectare depends on tree growth, which depends on the species and planting density. In high rainfall zones with good soil, it may take 3-5 trees over 25 years to sequester 1 tonne of CO2e. In lower rainfall zones with poorer soil, it could take as many as 15 trees!
Our planting sites adhere to methodologies developed by the Australian Government’s Emissions Reduction Fund (ERF). Several of our projects are also registered with the ERF. To measure carbon uptake at relevant planting sites we use the Full Carbon Accounting Model (FullCAM) which was developed by CSIRO and approved by the Australian Department of Environment.
To ensure offsets are not double-counted, we maintain an internal register (or ‘pool’) of offsets – allocating and retiring each offset as it is sold.
After planting, our projects are regularly monitored by external consultants to measure survival and growth rates, ensuring original sequestration estimates are accurate. We can provide planting and monitoring reports from all our projects on request.
For each planting project, we also enter into a legal agreement with the landholder(s) to ensure the trees are protected for at least 25 years and that the rights to count the carbon are secured.

There are over 14,500 carbon offset projects registered around the world which have generated almost 4 billion tCO2eto date. Carbon projects are typically categorised into the following 12 ‘activities’:
