Increasing carbon sequestration in land ecosystems is a common way to offset greenhouse gas emissions. We studied the carbon balance of an afforested wasteland site to demonstrate a method to quantify the offset units. The site manager spread an organic waste layer and planted spruce and birch seedlings with sown grass at the site. We monitored the carbon dioxide (CO2) balance and vegetation development for two years. We also projected the CO2 balance during the next 30 years using a process-based model and discussed implications for emission offsetting.
