    • advancing the circular carbon economy approach,
    • development and deployment of clean energy,
    • carbon capture and storage technologies,
    • diversification from reliance on hydrocarbon revenues, etc.

About is net-zero:

  • Net-zero refers to carbon-neutrality.
  • It does not mean that the said country would bring down its emissions to zero.
  • Rather, net-zero is the state in which the country’s emissions released are compensated by absorption and removal of greenhouse gases from the atmosphere.

Herd Immunity

Why in News?

The sero-survey of many cities indicate high levels of immunities gained by people, still these cities are witnessing high increase in number of cases. This is calling in question the concept of herd immunity.

About Herd Immunity:

  • Community immunity or herd Immunity occurs when a large number of people are vaccinated or have developed immunity against a disease, lowering the chances of others being infected by it.
  • When a sufficient percentage of population is vaccinated, it slows the spread of disease.
  • The decline of disease incidence is greater than the proportion of individuals immunized either by vaccines or recovering from virus.
  • It happens because vaccination reduces the spread of an infectious agent by reducing the amount and/or duration of pathogen shedding by vaccines, retarding transmission.
  • This approach requires infected people to build natural immunity and stop the human-to-human transmission. Thus, the disease spread will be subsequently halted.
