The Australian Conservation Foundation has put the 400 million 2005 Hazelwood expansion in context by comparing it to Victoria's five-star energy efficient homes standard, which is expected to save of greenhouse gases per annum. The ACF reasons that Hazelwood's operations would cancel out that benefit every four days. Former ACF Executive director Don Henry said he would follow formal objections with legal action to prevent the grant of 'new' coal to IPRH. Most of the West Field coal reserves were allocated to Hazelwood in 1996 in the privatisation process. The ACF did not mount any legal objection to Hazelwood's allocated coal reserves.
