CAT Exam 2015 preparation 6

A new report has laid bare the UK's pretensions to have cut greenhouse gas emissions over recent years. Ministers have claimed global leadership in reducing CO2 emissions and urged other nations to follow suit as production of CO2 in the UK is down 20% in the past two decades. But the official Climate Change Committee (CCC) said that the UK's total contribution towards heating the climate has actually increased as the overall contribution to emissions is up 10%.

Which of the following help resolve the paradoxical claims in the above passage?

OPTIONS
	1)	While the UK has been cutting emissions at home, it has been importing more goods from other countries, pushing up CO2 emissions there.
	2)	Each individual in the UK is responsible for only half of the production emissions of someone in other countries, which have kept their manufacturing base.
	3)	It is hard for any government including that of the UK to quantify imported emissions and difficult to influence other nations' climate policies.
	4)	UK's unilateral climate targets are forcing up energy prices and driving manufacturing jobs abroad.
