    This work should have some priority in the short term even though sf 6 emissions are proposed to be outside the ETS until 2013. Nearly all of New Zealand’s PFC emissions are sourced from anode effects while smelting aluminium. This makes ETS coverage relatively easy, as New Zealand Aluminium Smelters has good estimates of its emissions.
