Question Without Notice No. 1209 asked in the Legislative Council on 22 October 2019 by Hon Tim Clifford

Parliament: 40 Session: 1

Answered on


1209. Hon TIM CLIFFORD to the Leader of the House representing the Premier:

I refer to the response to question without notice 1186—C1267—and the fact that liquefied natural gas is predominantly methane.

(1) Does the Premier accept that methane is a greenhouse gas?

(2) Does the Premier accept that, according to the International Panel on Climate Change, methane warms the planet 86 times more than carbon dioxide does?

(3) Will the Premier concede that he did not take into consideration all factors relating to gas emissions, including methane, in his response to the claim that gas produces less than half the emissions of coal?

Hon SUE ELLERY replied:

I thank the honourable member for some notice of the question.

(1) Yes.

(2) The comparison of impact is dependent on the time frames for assessment, as methane has a shorter residence in the atmosphere. For example, the United States' EPA estimates the global warming potential of methane to be 28 to 36 times that of carbon dioxide over 100 years.

(3) No.
