What you need to know
2 മിനിറ്റ്
CCUS stands for Carbon Capture, Utilisation and Storage, a set of technologies that capture carbon dioxide from industrial sources and either reuse it or store it underground.
It is discussed as a climate mitigation option for hard-to-abate sectors.

പ്രധാന വസ്തുതകൾ
Remember these
- CCUS = Carbon Capture, Utilisation and Storage
- Captures CO2 from industrial sources such as power plants, cement and steel
- Captured CO2 is either reused (utilisation) or stored underground (storage)
- Seen as a mitigation option for hard-to-abate sectors
- Syllabus link: GS-III Environment, climate change mitigation

How the exam will ask it
പ്രിലിംസ്
- CCUS captures carbon dioxide from industrial sources and either reuses it or stores it underground.
- CCUS is discussed as a climate mitigation option for hard-to-abate sectors.
- Carbon capture addresses emissions at the source rather than removing them from the atmosphere.
മെയിൻസ്
GS-III (Environment): Hard-to-abate sectors such as cement, steel and fertilisers cannot cut emissions through electrification alone. CCUS offers a mitigation route by capturing CO2 and either reusing or storing it underground, but cost, energy demand and storage safety remain concerns. The way forward is pilot projects, clear policy support and its use alongside renewables and efficiency, not as a substitute.
Quick recall
Answer before you reveal
The "Victoria Mode", recently linked by IMD and IITM scientists to the expansion of semi-arid areas in north-west India, is an oceanic cycle of which ocean?
- Atlantic Ocean
- Pacific Ocean
- Indian Ocean
- Southern Ocean
ഉത്തരം കാണിക്കൂ
ഉത്തരം: B — Correct: Pacific Ocean — Right: the Victoria Mode is a Pacific oceanic cycle. • Atlantic Ocean — Wrong: Atlantic variability is described by the Atlantic Multidecadal Oscillation. • Indian Ocean — Wrong: the Indian Ocean's well-known cycle is the Indian Ocean Dipole. • Southern Ocean — Wrong: the Southern Ocean is not the source of the Victoria Mode.
