Through the process of photosynthesis, vegetation acts as a sink for atmospheric carbon. Photosynthesis is the process by which plants absorb CO2 from the atmosphere and, using solar energy and water, convert it into carbohydrates while releasing oxygen into the air.

There are two ways to do this:

- Use field measurements: directly via soil analysis, or indirectly via surface flux measurements.
- Develop tools to quantify it.

At netcarbon, we've opted for the second method, turning to space, to satellites, because from there we can see everything, all the time, all over the world.

Carbon capture through photosynthesis is essential in the fight against climate change. By absorbing CO2 from the atmosphere, this natural process helps limit the increase in its concentration, and thus limit the effects of human activities.

Carbon storage is the process by which CO₂ is captured and stored in natural or artificial reservoirs in order to reduce its concentration in the atmosphere. This can be achieved by various means, such as sequestration in soils, forests (through tree photosynthesis), oceans, or through carbon capture and storage (CCS) technologies.

Valorising carbon storage involves certifying CO₂ absorptions to obtain carbon credits. As a general rule, one tonne of stored carbon corresponds to one carbon credit. These credits can then be sold on the voluntary carbon market, making it easier to finance carbon storage projects.
At Netcarbon, we support you in certifying your renaturation projects using the Low Carbon Label.

The notion of "carbon storage" corresponds to the quantity of CO2 absorbed by vegetation, via photosynthesis, over one year (expressed in tCO2/ha/year). It differs from the notion of "carbon stock", which is defined as the quantity of carbon contained in soils at a given time.
