Synergic use of existing environmental certification schemes can support impact neutrality goals and future claims
This study empirically validates the TREEIN model by demonstrating how integrating existing environmental certification schemes, specifically FSC and Equalitas, with organizational life cycle assessment enables a Tuscan winegrowing company to quantify its carbon sequestration and achieve environmental impact neutrality.

Every farm is a balance sheet of nature, but for a long time, accountants have only looked at the debts. They counted the fuel burned, the water drawn, and the chemicals released, tallying up the damage a business does to the planet. What they often missed were the assets: the trees that pull carbon from the air, the soil that holds water, and the forests that clean the atmosphere. This imbalance makes it hard to know if a company is truly sustainable or just less harmful than it used to be. A new approach called TREEIN tries to fix this by forcing a single, honest calculation that weighs the harm caused by making a product against the good done by the land that grows it. It asks a simple, difficult question: can the positive work of nature cancel out the negative work of industry?
In the rolling hills of Tuscany, Italy, a wine and olive oil company named Arillo in Terrabianca became the first real-world test for this idea. The researchers did not just build a theory; they walked the fields, measured the trees, and tracked every drop of water and every liter of fuel used by the company in 2022. They started by mapping the entire life of a bottle of wine, from the moment a grape is planted to the moment the bottle is sold. This process, known as an organizational life cycle assessment, revealed that the company's activities released a specific amount of greenhouse gases into the atmosphere. Most of this came from the energy used to make the wine and the diesel burned by tractors, with a significant portion coming from the supply chain, such as the glass used for bottles and the transport of goods.
But the story did not end with the emissions. The team then turned their attention to the company's forests, which cover about 130 hectares across three different estates. They measured the height and girth of thousands of trees and analyzed the soil to calculate how much carbon these woods were storing. The results were striking. The forests were absorbing nearly twice as much carbon from the air as the entire company emitted through its farming, winemaking, and distribution activities. In a single year, the trees and soil acted as a massive sponge, soaking up the equivalent of 989 tons of carbon dioxide, while the business operations released only about 450 tons.
This finding suggests that the company is already in a state of environmental balance, where the natural capital it manages offsets the damage caused by its production. However, the researchers are careful to note that this is not yet a claim of total "neutrality" in the strictest sense, because the company has not yet taken extra steps to reduce its emissions further or to actively boost the growth of its forests beyond their current state. To move from a passive balance to a verified, active solution, the company is now implementing a management plan to care for its woods more carefully, ensuring they continue to grow and store carbon. They are also planning to switch to solar power and use lighter bottles to cut their emissions even further.
The study proves that it is possible to combine two different ways of measuring the environment: one that counts the pollution and another that counts the benefits of nature. By using existing certification systems for forests and sustainability, the researchers showed that a small agricultural business can create a clear, data-driven picture of its total impact. The work demonstrates that when a company owns the land that supports its business, it has a unique opportunity to turn its environmental debt into a surplus. The path forward involves continuous monitoring to ensure that the forests keep growing and the emissions keep falling, turning a theoretical balance into a lasting reality for the land and the people who work it.
