I asked about whether the government has conducted economic modelling on the impact of signing this agreement. The PRESIDENT: And the minister is being relevant to your question. Senator FARRELL: You were part of a government and an opposition that supported the move to net zero by 2050. We're not going to get to net zero without the continued use, for instance, of gas. We simply can't switch off gas and turn on renewables. That's just not the way the world works. And this government and the Prime Minister himself— (Time expired) The PRESIDENT: Senator Henderson, second supplementary?
