The Government's independent climate advisers said there are good reasons for New Zealand to increase its 2050 climate target. The Climate Change Commission said New Zealand's current effort doesn't meet international criteria for doing its fair share. Also, it says if the Government lowers methane targets, under a review announced last week, other sectors of the economy will have to do more. A third consultation document out today said New Zealand should consider bringing international aviation and shipping into its climate targets - two huge areas currently excluded. It is asking the public for feedback on raising the bar, or, on the flipside, whether there are good reasons why New Zealand should keep the target the same. RNZ's Climate Change correspondent Eloise Gibson speaks to Lisa Owen.
