All major parties have supported the net zero carbon legislation. Given the efficiency of trees as a carbon sink we can be assured of a focus on tree planting into the longer term. Government management of the carbon price has been sufficient for the ETS to be effective in ensuring harvested trees are replanted but as yet the price hasn't been managed to a level to finance significant new planting. All eyes are on agriculture. If their separate carbon regime, due over the next couple of years, is more successful in encouraging new planting, what will be the implications for the ETS system?
