Calling for a moratorium on new coal mines in NSW just hours before a Hunter Valley MP quit, trigging a by-election, contributed to Malcolm Turnbull being dumped from a clean economy job. NSW Environment Minister Matt Kean has admitted the comments made by the former Liberal prime minister on ABC radio a day after he was made chair of the state's new Net-Zero Emissions and Clean Economy Board helped seal his fate. 'It wasn't helpful,' Mr Kean told ABC radio on Wednesday. Malcolm Turnbull has been dumped from his new job as the NSW government's climate change tsar Mr Turnbull's five-year appointment rankled many of Mr Kean's conservative coalition colleagues, given his comments about the coal industry.
