What is New Zealand's fair share of GHG emissions?

I was playing with this widget on the World Bank's website.
I have graphed New Zealand's carbon dioxide emissions per capita⁽¹⁾ against per capita for World, the European Union, China and sub-Saharan Africa.

New Zealand very much has a developed country consumption pattern.

CO2 emissions (metric tons per capita)

Data from World Bank

(1) CO₂ only and not all greenhouse gases expressed as CO₂ equivalent. So methane and nitrous oxide are not included.
