How we work out the numbers

CO₂ emissions for a given period are worked out as follows:

Energy generated in Spain during the period (MWh) x Emission Factor for Spain (tCO₂/MWh) = CO₂ emissions avoided for the period in Spain (tCO₂)
+
Energy generated in Germany during the period (MWh) x Emission factor for Germany (tCO₂/MWh) = CO₂ emissions avoided for the period in Germany (tCO₂)
=
Etc. (an equation for each country).
=
the sum of the CO₂ emissions avoided Turing the period in all the countries in which ACCIONA generates renewable electricity.
