Teak absorbs max CO2 from air, helps check global warming
May 09, 2016
- A study conducted by the Gujarat Ecological Education and Research (GEER) to prepare a hierarchy of local trees in India that can reduce the carbon dioxide content of the atmosphere has found that ak has the highest capacity for carbon sequestration among trees in India.
- In its lifetime, a teak tree with a girth of 10-30 cm can absorb 3.70 lakh tonnes of carbon dioxide from the atmosphere.
- GEER has sent a list of trees with high capacity for carbon sequestration to different state forest departments that can choose them for plantation in areas whe re CO2 emission is high.
What is Carbon sequestration
Carbon sequestration is the process by which carbon dioxide is captured from the atmosphere by trees for long-term storage.
Significance of study:
- Different tree species sequester different quantities of carbon dioxide. There is, however, inadequate knowledge about carbon sequestration potential of different tree species.
- The GEER study will fill this knowledge gap and the choice of species is crucial to the total amount of carbon dioxide absorbed from the atmosphere.
- The study will help researchers and different state forest departments to calculate the carbon sequestration potential of the trees they have.
- It will also help different forest departments go in for plantation of trees with high capacity for absorbing carbon dioxide from the air where CO2 emission is high.
