== Explanation ==
[[File:En-en_adult_card_7_front.png|400px]]
 
CO<sub>2</sub>, or carbon dioxide, is the main anthropogenic (produced by human activities) greenhouse gas in terms of emissions. These emissions come from our use of fossil fuels and from deforestation.

=== Causes ===
=== Causes ===
* [[En-en adult card 6 deforestation|Deforestation]] emits CO2 because 93% of man-made deforestation is done by burning forests.
* [[En-en adult card 5 fossil fuels|Fossil fuels]] Coal, oil and natural gas emit CO<sub>2</sub> during combustion.
* [[En-en adult card 5 fossil fuels|Fossil fuels]] : Coal, oil and natural gas emit CO2 during combustion.
* [[En-en adult card 6 deforestation|Deforestation]] emits CO<sub>2</sub> because a large proportion of deforestation caused by man is achieved by burning the forests.

==Current energy mix==
=== Global ===
The global energy mix is 85% dependent on fossil fuels<ref> [https://www.planete-energies.com/en/medias/close/what-energy-mix Global energy mix] </ref> and today renewable energy sources tend to add capacity rather than replace fossil fuels.

*Fossil fuels: 67.4% (coal 1.9%, oil 44.0%, natural gas 21.5%)
*nuclear: 17.7%
*renewables: 14.9% (biomass-waste 9.8%, hydropower 3.0%, wind 1.2%, solar 0.5% (mainly photovoltaic), other 0.3%).
