Senator BIRMINGHAM (South Australia—Minister for Finance, Vice-President of the Executive Council and Leader of the Government in the Senate) (14:08): I thank Senator Keneally for her question. Indeed, as the Prime Minister has made clear, it is important for Australia to drive towards net zero emissions, to play its role in the development of new technologies, to invest in technologies, not taxes—as those opposite would have—and to make sure that in doing so Australia, which has been such a crucial leader in relation to energy sources in the past, continues to be a crucial leader in the delivery of energy sources now and into the future. That's why, whilst at the G7 and associated meetings, the Prime Minister was furthering the policy commitments made in terms of the pursuit of hydrogen hubs around the country, the pursuit of the stretch target to achieve the delivery of hydrogen at $2 per kilogram and the pursuit of strong international partnerships in that regard. The Prime Minister pursued agreements whilst overseas and signed them—with Germany and Singapore, for hydrogen cooperation with those key economies and key investors in Australia, as we've pursued with Japan, as well. It's this type of investment by coalition governments that has enabled Australia to reduce its emissions, not with the taxes proposed by those opposite— The PRESIDENT: Senator Keneally, a point of order? Senator Keneally: Yes, on relevance: the question was fairly tight and clear. Is net zero a position of the Morrison-Joyce government, yes or no? The PRESIDENT: I can't instruct the minister the terms in which he or she must answer the question as long as the minister is directly relevant to it, and I think the minister is clearly being directly relevant. There's a chance after question time to debate ministers' answers. Senator BIRMINGHAM: Australia beat its Kyoto-era targets by some 459 million tonnes. Australia's emissions are down over 20 per cent from the period 2005 to December 2020. That's compared with an OECD average of 6.6 per cent. This is what achieves a pathway to net zero: achieving real emissions reductions through real investment in real technologies. The PRESIDENT: Senator Keneally, a supplementary question?
