Eucalyptus is a tree species native to Australia and one of the most efficient in terms of CO2 sequestration. In fact, eucalyptus trees planted in regions with high rainfall and high photoperiod have a very rapid growth and consequently one of the highest sequestration rates in the world.
Eucalyptus, planted in tropical regions characterized by abundant rainfall as those of our projects, is a very efficient "Carbon Removal" in other words a real CO2 sequestration machine.2.
Trees in general, possess this function, but the eucalyptus is the one that does it most efficiently.
The main benefits of reforesting degraded areas with this species are:
- Maximum absorption of CO2: : In Brazil, thanks to a favorable photoperiod and abundant rainfall, eucalyptus has a faster growth and therefore a very high efficiency in CO2. sequestration.
- High oxygen production: Thanks to chlorophyll photosynthesis, plants can transform CO2 and H2O into O2 and glucose, according to the following equation:
6CO2 + 6H2O + solar energy6H12O6 + 6O2
In tropical environments, eucalyptus also captures CO2, but it does so with an efficiency 5 times higher than tree species in temperate zones.
- Less water consumption than other species: Eucalyptus water use is 306 liters/kg of dry material, which is one of the lowest when compared to tree species such as oaks (400 liters/kg), and agricultural crops such as corn (1,000 liters/kg) and cotton (3,200 liters/kg).
- Low nutrient requirements from the soil: Plants need nitrogen, phosphorus, and potassium (NPK) for their development. Eucalyptus trees have one of the lowest requirement rates with 4.8 (kg/hectare/year) of nitrogen, 1.3 of phosphorus and 6 of potassium. This is lower than other species such as poplar or willow.
- Does not cause soil desiccation: Eucalyptus species have an average root depth of about 0.5 to 1.5 meters, their root system is more specifically adapted to use soil moisture supplied by precipitation from the upper soil profile, rather than from the water table at a considerable depth. For this reason, the species contributes to not drying out the soil.
- It has a low flammability rate: Unfortunately, wildfires are still a present phenomenon in Brazil. Eucalyptus trees have one of the lowest fuel load parameters, as well as a low flame height, which allows, if necessary, to better control fires.
- Protects biodiversity: The eucalyptus trees planted in our projects act as biological corridors that reconnect the native forest of the Cerrado area with the new reforested area, giving animals a zone of refuge and protection.
