India’s Carbon Stock in Forests
Complete Notes for Competitive Examinations
By Home Academy
Introduction
Forests are known as the green lungs of the Earth because they absorb carbon dioxide (CO₂) from the atmosphere and store it in the form of carbon. This stored carbon is called Carbon Stock. Carbon stock plays an important role in reducing climate change and global warming.
India is one of the world’s major forest-rich countries and continuously monitors its forest resources through periodic assessments. Forest carbon stock is an important indicator of environmental sustainability and is frequently asked in examinations such as UPSC, JKSSB, JKPSC, SSC, UGC NET, Banking, and State PCS exams.
What is Carbon Stock?
Carbon Stock refers to the total amount of carbon stored in forest ecosystems.
Forests absorb atmospheric CO₂ through photosynthesis and store carbon in different components.
Formula (Concept)
Atmospheric CO₂ → Photosynthesis → Carbon Storage
Components of Forest Carbon Stock
1. Above-Ground Biomass
Carbon stored in:
Tree trunks
BranchesLeaves
Shrubs
This component stores a significant portion of visible forest carbon.
2. Below-Ground Biomass
Carbon stored in:
Roots
Underground plant structuresRoots help lock carbon inside the soil.
3. Dead Wood
Carbon present in:
Fallen trees
Dry branchesDecomposing wood
Although trees die, stored carbon remains for many years.
4. Forest Litter
Includes:
Dry leaves
BarkTwigs
Organic waste on forest floor
5. Soil Organic Carbon (Most Important)
This is the largest carbon storage component.
Stored in:
Soil
Decomposed organic matterRoot residues
Exam Point:
Soil Organic Carbon stores the highest proportion of carbon.
India’s Forest Carbon Stock (Latest Figure)
Total Forest Carbon Stock of India:
7,285.5 million tonnes
Increase:
India recorded an increase of approximately 81.5 million tonnes over the previous assessment.
CO₂ Equivalent:
Approximately 30.43 billion tonnes of CO₂ equivalent.
India’s Forest and Tree Cover
Total Forest & Tree Cover:
25.17% of India’s geographical area
Forest Cover:
21.76% of India’s geographical area
Tree Cover:
Remaining percentage contributed by trees outside forests.
Carbon Sink and India’s Climate Goals
What is Carbon Sink?
A carbon sink is any system that absorbs more carbon than it releases.
Examples:
Forests
Oceans
Soil
India’s forests act as a major carbon sink.
India’s Target by 2030
India aims to create an additional:
2.5–3.0 billion tonnes of CO₂ equivalent carbon sink
through:
Forest expansion
Afforestation
Tree plantation
Sustainable forest management
Importance of Forest Carbon Stock
Environmental Importance
Reduces global warming
Controls greenhouse gases
Maintains ecological balance
Economic Importance
Supports sustainable development
Protects natural resources
Social Importance
Improves livelihoods
Supports biodiversity
