What is Blue Green Ecosystem ? 

Ans Blue carbon ecosystems such as mangroves, seagrass meadows, and salt marshes are coastal and marine habitats that naturally capture and store carbon dioxide from the atmosphere. 

India’s Nationally Determined Contributions (NDCs) under the Paris Agreement do not specifically mention "blue carbon ecosystems" as a separate target. However, they emphasize increasing forest and tree cover to create an additional carbon sink of 2.5 to 3 billion tonnes of CO₂ equivalent by 2030. While not directly stated, the protection and restoration of blue carbon ecosystems like mangroves, seagrasses, and salt marshes support India’s broader climate goals of mitigation and adaptation
