Question 65: Environment and Ecology

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 ?

a1 only

b2 only

cBoth 1 and 2

dNeither 1 nor 2

AnswerUPSC’s answer is (b).

The Climate and Clean Air Coalition to Reduce Short-Lived Climate Pollutants was launched in 2012 by a group of countries (the United States, Canada, Sweden, Mexico, Ghana and Bangladesh) together with UNEP, and it is not an initiative of the G20, so Statement 1 is wrong. It focuses on short-lived pollutants including methane, black carbon and hydrofluorocarbons, so Statement 2 is right. Remember: CCAC targets methane, black carbon and HFCs.

1. It was launched by a few countries with UNEP in 2012, not by the G20.
2. It targets methane, black carbon and HFCs.

How you could have got this

If you were sure statement 1 is not correct, (a) and (c) go: each of them includes 1.
What you needed to know: It was launched by a few countries with UNEP in 2012, not by the G20.
Then, if you were sure statement 2 is correct, (d) goes: it leaves 2 out.
What you needed to know: It targets methane, black carbon and HFCs.

Only (b) is left. This one needs every statement.

Which options go is worked out from UPSC’s key and the options, not by a model.

Why each option is right or wrong

(a) Wrong: it was not launched by the G20.
(b) Right: only Statement 2, on methane, black carbon and HFCs, is correct.
(c) Wrong: statement 1 is false.
(d) Wrong: statement 2 is correct.

Answer: UPSC’s key. Explanation: written by UPSC Grade, not by UPSC.
