The second aspect of effective action is that policies should demonstrate a minimum level of effectiveness before they are funded. In practice, minimum effectiveness will be a cap on the number of dollars the Government will commit to spend on a policy to cut a tonne of emissions. Policies that do not reach the minimum threshold of effectiveness should not be funded and the money saved should go to other more effective policies. This cap would certainly rule out the Government's 100 percent renewable electricity goal, which actually has been costed at around $1,280 per tonne. New Zealand can make great progress towards emissions targets simply by redirecting spending from bad policies to better and more effective options.
