"An immoral under-investment
Even when our system is in place, it will still be 2040, the National-led government estimates, before its objectives are fully met. The cost to the country of doing so will be $2bn, equal to $90m a year, or a mere 0.034% of current GDP. That is an immoral under-investment in our environment."
