Like any forested or vegetation covered area a patch of green on top of a roof should theoretically lower levels of carbon dioxide in the air as well.
Green roof co2.
Plants breathe in the greenhouse gas like we.
Reduces the ambient temperature.
Green roofs are considered effective in the reduction of atmospheric co2 because of their ability to reduce energy consumption of buildings and sequester carbon in plants and substrates.
So this helps to create a cooler and more pleasant climate.
Plants absorb sunlight 50 is absorbed and 30 reflected.
The plants in a green roof filter particulate matter from the air and convert co2 into oxygen.
It takes seven years for the roof to offset the carbon used for its building materials and become truly carbon.
Greening conventional roofs requires special materials which come at a carbon cost.
