In News: A report on the policy framework of the Carbon Capture Utilisation and Storage or CCUS prepared by the Niti Aayog and MN Dastur & Company says CCUS has a critical role to play for the country to halve CO2 emissions by 2050 and reach net-zero by 2070.

  • India’s per capita CO2 emissions were about 1.9 tonnes per annum, which was less than 40% of the global average and about one-fourth of that of China.

About CCUS:

  • It is the technology for decarbonising carbon dioxide (CO2) from high polluting sectors such as steel, cement, oil, gas, petrochemicals, chemicals and fertilisers (contribute to 70% of emission).
  • The technology would help in promoting the low carbon-hydrogen economy and in removal of the CO2 stock from the atmosphere.
  • It could enable the production of clean products while utilising rich endowments of coal, reducing imports and thus leading to a self-reliant India economy.
  • It could enable sunrise sectors such as coal gasification and the nascent hydrogen economy in India.
  • Creation of value-added products such as green methanol, green ammonia
  • The key challenge would be to reduce the cost of the mechanisms to implement the technology.
  • CCUS policy should be carbon credits or incentives based, to seed and promote the
  • CCUS sector in India through tax and cash credits and later should transition to carbon taxes.
