David Farrar: Meaningless data

Don Brash writes:

Successive New Zealand governments, as governments in many other countries, have adopted policies designed to discourage the emission of greenhouse gases, or to encourage measures which would absorb such gases. By far the most logical of these measures is the Emissions Trading System (ETS). Other policies, such as subsidies for electric vehicles, have no logic at all: if switching to electric vehicles were the lowest cost way of reducing emissions, the ETS would already be encouraging that switching without subsidies. And if it isn’t, the subsidies push us into higher cost ways of getting to Net Zero.
