What are the best trees able to absorb CO2 emissions? There are several of them, with truly amazing properties. Betula pendula, a plant with a splendid and elegant habit, can absorb up to 3100 kilos of CO2! Birch is a plant capable of growing on the most difficult soils and considered a sacred tree by the Celts and the Germanic tribes.
Trees such as Acer Platanoides, Celtis australis and Tilia cordata should not be forgotten, all with great absorbency. The Ash is one of them. it is a common tree that can reach 40 meters and that manages to block up to 2600 kg of CO2 and to guarantee a strong absorption of gaseous pollutants.
The lime tree is also among the anti-smog trees: it is among the longest-lived with deep and firm roots like those of the field elm. Ginko Biloba is an ancient tree whose origins date back to 250 million years ago, and, in addition to absorbing 2800 kg of CO2, it also boasts a high barrier capacity against gas, dust and heat, as well as a strong adaptability to all land including urban ones.
Threes able to absorb CO2 emissions: here what they are
Among these, acer platanoides reaches a height of 20 m, sometimes even 30 m. The trunk is slender and straight, the crown is oval with main branches that stretch upwards.
The crown is composed of deciduous leaves, light green on both sides, palmate with 5 shallow and toothed lobes. They are large, 10–15 cm with an often curved tip at the end. The petiole 8-10 cm long, reddish in color, if it is broken it emits latex.
The foliage turns bright red in autumn. It has reddish scaled buds with an olive-colored spot at the base, the leaf scars touch each other. The bark is smooth in young trees, thin and grayish-brown, increasing in thickness becoming covered with cracks and fissures longitudinally in the adult plant, without however detaching in plates.
The flowers are glabrous and greenish-yellow, with 8 stamens, emerging before foliation. They are used by bees to make honey. The fruits are unshaped with wings diverging at 160°. They are long pedunculate: the wings are 40–55 mm long and about 7–8 mm wide. They ripen in September-October. The root system is similar to sycamore maple, it does not produce suckers.
