Consider the following statements:1.Climate and Clean Air Coalition (CCAC) to Reduce Short Lived Climate Pollutants is a unique initiative of G20 group of countries.2.The CCAC focuses on methane, black carbon and hydrofluorocarbons.Which of the statements given above is/are correct?

A 1 only
B 2 only
C Both 1 and 2
D Neither 1 nor 2

Correct answer: (b) 2 only

Explanation

  1. A

    1 only

    Option (a) is 1 only. The Climate and Clean Air Coalition was launched in 2012 by UNEP with a first group of countries (including Bangladesh, Canada, Ghana, Mexico, Sweden and the United States), not as a G20 initiative. Statement 1 is false. This option is not the key.

  2. B

    2 only

    Statement 2 is correct: CCAC targets short-lived climate pollutants, especially methane, black carbon and hydrofluorocarbons. Statement 1 is false. Hence 2 only is the official key.

  3. C

    Both 1 and 2

    Option (c) is both. The G20-origin claim knocks statement 1 out. This option is not the key.

  4. D

    Neither 1 nor 2

    Option (d) is neither. The pollutant focus in statement 2 is accurate, so neither fails. This option is therefore wrong.

Summary. Official key is (b) 2 only. CCAC is a UNEP-hosted voluntary coalition on short-lived climate pollutants, not a G20 body. Its headline SLCPs are methane, black carbon and HFCs, which also harm air quality. CO2 remains the long-lived stock pollutant handled mainly under UNFCCC. Only statement 2 is correct.
