Carbon Sink / Carbon Sequestration क्या है?
ऐतिहासिक पृष्ठभूमि
मुख्य प्रावधान
8 points- 1.
Natural Carbon Sinks: Oceans (absorb a significant portion of atmospheric CO2, e.g., Southern Ocean absorbs approximately 40% of human-emitted CO2) and Forests and Soils (plants absorb CO2 during photosynthesis, storing carbon in biomass and soil organic matter).
- 2.
Artificial Carbon Sinks / Carbon Capture and Storage (CCS): Technologies designed to capture CO2 from industrial sources and store it underground in geological formations.
- 3.
Role in Climate Regulation: Carbon sinks help mitigate climate change by removing CO2 from the atmosphere, thus reducing the greenhouse effect.
- 4.
Saturation Risk: Natural sinks can become saturated or even turn into sources if environmental conditions change (e.g., deforestation, ocean warming).
- 5.
Blue Carbon: Carbon stored in coastal and marine ecosystems like mangroves, salt marshes, and seagrass beds, which are highly efficient carbon sinks.
- 6.
Carbon Cycle: Sinks are integral to the global carbon cyclethe biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.
- 7.
Afforestation and reforestation are key strategies to enhance terrestrial carbon sinks.
- 8.
The efficiency of carbon sinks can be influenced by factors like ocean stratification and ocean currents.

Evolution of International & Indian Carbon Sink Policies
This timeline traces key international agreements and India's significant commitments related to carbon sinks and climate action, highlighting the increasing global focus on sequestration.
The understanding and policy focus on carbon sinks have evolved significantly since the late 20th century, driven by increasing scientific evidence of anthropogenic climate change. International agreements and national policies now increasingly integrate strategies for enhancing carbon sequestration.
