The first action of that new National Government in the climate change sphere was to expand a programme of what is called free allocation. Free allocation is something that many people a whole lot smarter than myself—researchers and experts, a whole lot more informed than many in this House—have spilt a lot of ink on. But the simple explanation is this: the emissions trading scheme means that polluters pay for their pollution, and they are limited in how much pollution they can produce. But unfortunately, this story is, of course, not that straightforward. It's actually probably rather reflective of the lobbying power of those already wealthy and powerful, but their arguments that they shouldn't pay for their pollution were reflected in a concept of free allocation. It gives our most polluting industries an allocation of those emissions trading scheme units for doing nothing except exorbitantly polluting, supposedly so that they can be incentivised to reduce that polluting. That is not a just transition. It is corporate welfare. But after being elected, the 2008 National Party Government froze that annual generous grant of free allocation, which was originally supposed to be a sinking lid. It meant that even as technology developed and industries got more carbon efficient and, thankfully, began producing less carbon, they continued to get the same free ride. So even the National Party, who so often invoke the free market, should know and recognise that that is a messed up and significant market distortion.
