What is the primary reason CCUS is considered essential for achieving carbon neutrality in India by 2070?
|
To manage and reduce CO2 emissions from heavy industries. |
|
India’s goal is to offset CO2 emissions from sectors where emissions are difficult to eliminate. CCUS helps in capturing and storing CO2, making it a key tool in its broader strategy. |

|
1.5 billion metric tonnes |
|
Reduction= 3billion metric tonnes x 0.50= 1.5billion metric tonnes
Target emissions= 3billion metric tonnes − 1.5billion metric tonnes= 1.5billion metric tonnes |
