Association Webinars: The Role of Fundamentals and Policy in New Zealand's Carbon Prices



  

 

The New Zealand Emission Trading Scheme (NZ ETS) is the second oldest national ETS in the world and is unique in that it includes forestry as a carbon sink (a source of unit supply). Further, NZ ETS has been subject to many policy changes including a switch from allowing unlimited importation of units to becoming completely autarkic. In this context, we analyse NZU pricing dynamics driven by the interaction between allowances supply and demand during the period of July 1st, 2010 to December 31st, 2019 and for two sets of subperiods divided by the official and actual de-link dates. Having controlled structural break effects associated with two policy events in our models, we identified a significant relationship between the supply drivers and NZU price returns over different horizons. Namely, our empirical models find that international offset negatively affected NZU returns before the actual de-link date, domestic supply after the official de-link date, and banked units between the official and actual de-link dates, and that green offsets, surprisingly, positively affected NZU returns before the actual de-link date. Our results also highlight that from a demand perspective, sectoral effects had significant relationships with NZU returns with different dynamics. Namely, manufacturing and construction activities shifted to negatively affect NZU returns after the official de-link date, implying that fixed allocative baselines have resulted in over-allocation over time. Stationary energy sector activities shifted from negatively to positively affecting NZU returns after the official de-link date probably due to their exploitation of unlimited international offset during the linking period.
