House of Assembly Fifty-Third Parliament, Second Session (53-2) 53 2 Parliament of South Australia House of Assembly published Question Time Emissions Trading Scheme Emissions Trading Scheme Mr KNOLL House of Assembly Schubert Emissions Trading Scheme Mr KNOLL (Schubert) (14:56): Supplementary, Mr Speaker: I can try again. The question is to the Treasurer. Is the Treasurer aware of any carbon schemes, whether they be market based or a form of carbon tax, that are being investigated by his cabinet colleagues? The Hon. J.W. WEATHERILL House of Assembly Cheltenham Premier Emissions Trading Scheme The Hon. J.W. WEATHERILL (Cheltenham—Premier) (14:57): I can add no further than to repeat what I have said. We have a discussion paper, which I am sure the honourable member can find using that new-fangled device he has in front of him—the computer. It might be on the internet, or the interweb as my honourable colleague so often describes it. It is there to elicit an open debate about how we respond to climate change. If those opposite want to engage in this debate in an open and honest fashion they might consult their neoliberal principles and promote a market-based mechanism for dealing with climate change and carbon pollution.
