15%, | 15% is not much, but it varies a lot depending on the country and lifestyle. In Western countries, the share of transportation, especially air travel, can account for a very large part of everyone's carbon footprint. In fact, if you take one or a few long haul flights a year, that's the bulk of your carbon footprint. | ||

=== | === French energy mix === | ||
In France, transport is the leading GHG emitting sector with 28% of emissions <ref>[https://jancovici.com/wp-content/uploads/2020/07/Jancovici_Mines_ParisTech_cours_3.pdf#section.0.41 Cours Jancovici Mines ParisTech, cours 3, section 41]</ref>. | |||
The individual car represents 67% of the carbon footprint of transport, that's huge ! <ref>[http://ravijen.fr/wp-content/uploads/2018/11/empreinte_FR_2016_graphe.jpg, Ravijen]</ref> | |||
France energy mix is 70% dominated by nuclear power, which is a low carbon energy (hydraulic 11%, focile 8%, ...) <ref>[https://opendata.reseaux-energies.fr/explore/dataset/prod-national-annuel-filiere/table/?sort=annee&dataChart=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%3D, opendata.reseaux-energies.fr] </ref> (l'électricité ne représente que 24% de l'énergie consommée en france <ref>[https://fr.wikipedia.org/wiki/%C3%89lectricit%C3%A9_en_France, page wikipedia sur l'électricité en France]</ref>). Donc une voiture électrique en France sera moins émettrice de CO2 qu'une voiture à énergie fossile, mais dans le calcul des émissions au kilomètre, il faut inclure les émissions liés à la fabrication de la voiture. Donc, c'est mieux mais cela n'est pas zéro émission comme le laisse entendre certaines publicités. | |||
