Today in Parliament, National's Gerry Brownlee attacked the government's biofuels sales obligation as imposing an excessive cost for emissions reduction compared to other options. Partly, this was based on bad numbers - Brownlee derived his cost by dividing the $125 million capital cost by the 1 million tons of CO2 saved over the five year Kyoto First Commitment Period, which straps the chicken by completely ignoring future savings. But apart from that shoddy exercise, there's also the interesting fact that a biofuels obligation is official National Party policy [PDF], and that back in February, Nick Smith was complaining that the government wasn't implementing it fast enough!
It would be nice if the National Party would make up its mind where it stood on this issue. Does it support biofuels or not? Because it can't have it both ways - at least not if it wants to retain any credibility with the electorate.
