NZ Fuel Emissions, as graphed in the shiny app.

A quiz:

The above picture shows the greenhouse gas emissions produced in NZ from 1990 to 2010 from three sources. These are, in no particular order, liquid fuel (e.g. petrol), gas, and coal. The question is: which is which? And, how do you know?

If you’ve given up, you can find out the answer (and many more) for yourself on the Shiny app that produced this graph. Enjoy!
