 ## Definition of indicator
 
-- CO2 per capita (metric tonnes per person): Carbon dioxide emissions from the burning of 
-fossil fuels (metric tonnes of CO2 per person). 
-- Yearly CO2 emissions (1000 tonnes): Total carbon dioxide emissions from the burning of
-fossil fuels during the given year (1000 metric tonnes of CO2).
-- Cumulative CO2 emissions (tonnes): Total CO2 emissions from fossil fuel for the period 
-between 1751 and the relevant year in metric tonnes.
