Shankar IAS Test: Mitigation Strategies - UPSC MCQ

CCS technology is designed to capture CO2 emissions from large point sources and store it underground or in other secure locations, preventing it from entering the atmosphere.

Carbon storage can be categorized into natural sinks, which absorb carbon naturally, and artificial sinks, which are created by humans for the purpose of storing carbon.

The process begins with trapping and separating CO2, followed by transporting the captured CO2 to a storage location, and finally storing it securely away from the atmosphere.

Hydrodynamic trapping relies on cap rock impermeability, solubility trapping involves the dissolution of CO2, and mineral carbonation involves chemical reactions forming stable carbon compounds.

Green carbon is related to terrestrial ecosystems, while blue carbon refers to carbon captured and stored in marine and coastal ecosystems.

Blue carbon ecosystems play a crucial role in storing carbon and thus help mitigate climate change, making the protection and restoration of these ecosystems extremely important.

Carbon credits are part of an international emission trading system where a credit allows the emission of a certain amount of carbon dioxide or other greenhouse gases, with the aim of reducing total emissions.

Carbon offsetting not only helps reduce greenhouse gas emissions but often also brings socio-economic benefits to the locations where offsetting projects are implemented.

A carbon tax offers predictability and incentivizes clean energy investments. In contrast, 'cap and trade' is complex and not as quick to implement as a carbon tax, making Statement 2 incorrect.

While the universal carbon tax is a climate change mitigation strategy, it is not considered a method of geoengineering, which involves large-scale engineering of the environment to combat global warming.
