It has long been the National Party's position for many years that the primary policy tool for dealing with climate change should be a well-designed, pure emissions trading scheme (ETS). It was the National Government in 2010 that introduced the emissions trading scheme. We knew it was the most effective and efficient tool for reducing our emissions and for fulfilling our climate change obligations. It was this ETS that enabled the National Party to lift our renewable energy production from 65 percent to 85 percent during our time in office, a trend that I would note has stalled and probably actually gone backwards under this, you know, greenest Government ever. But it is our view that the emissions trading scheme is the most effective tool.
