The New South Wales government estimates the cost of meeting its 2030 climate target at about $140 per tonne of climate pollution. That means this delay could cost a cool $3.5 billion. This is NSW’s third coal power station life-extension in three years, as owners decide that climate inaction is more profitable than the hard work of building replacement clean generation. Simply stopping the approval of new mines and extensions would cut emissions significantly. While the NSW government have made efforts to bring renewable energy online, the extension of Eraring shows that not nearly enough has been done.
