Grass has much more than decorative virtues. Occupying 90-95% of green areas in private gardens and public green spaces, its contribution is multiple:
- It filters dust particles in the air,
- Thanks to photocatalysis, it captures polluting gases (CO2, NO2)
- It filters rainwater by capturing heavy components,
- It absorbs noise in the city,
- It reduces temperatures.
According to a British study (*), grass captures twice as much carbon as a deciduous forest (oak, poplar, mulberry), for the same floor area.
Thus, for an area of 1,000 m2, the lawn:
- Produces the amount of oxygen needed for 16 people,
- Captures the CO2 production of 3 cars.
