So, let us assume a baseline GDP growth of 2% per year. The GDP numbers in the table need to be interpreted as relative to the baseline.

On whether this is low, high or outrageous we can debate, but if fully passed on to consumers it would make a round trip Amsterdam – New York US$ 200 more expensive. In the Dutch Central Bank scenario Kirk refers to we model the impact of a US$ 100 increase in the carbon price.
