In this study, different ways to calculate how planting trees can help tackle climate change are explored. The researchers looked at how to measure the amount of carbon dioxide absorbed by farm-forestry projects in Australia. They analyzed four methods to see how they could affect investors and landowners financially. The study focused on how these methods compare in estimating carbon sequestration and the costs involved. The findings suggest that the way carbon sequestration is accounted for can have significant economic impacts on those involved in reforestation projects, like farmers and investors.
