Senator DI NATALE (Victoria—Leader of the Australian Greens) (14:20): Minister, 80 per cent of the thermal coal that Australia digs up is shipped off and burnt overseas. Your policy and, indeed, the opposition's policy, is to do nothing about the biggest contributor to global warming in this country. Do you accept that, unless we phase out the mining and burning of coal both here in Australia and overseas, we're going to see more disasters and more Australians affected?
