Abstract

[eng] We use 2009 technical data to assess the economic efficiency of three second-generation biodiesel production technologies in the fight against greenhouse effects. To do so, we estimate the cost of reducing greenhouse-gas emissions. The environmental impact is definitely positive , but production costs remain high. The cost per metric tonne of CO2 avoided exceeds €100 for all the technologies studied. However , there is a strong uncertainty concerning many parameters. We have not assessed the potential cost-reduction gains from technical progress, which may be substantial. [fre] Cet article cherche à évaluer, sur la base des données techniques de 2009, l‘efficacité économique de trois technologies de production de biodiesel de seconde génération dans le cadre de la lutte contre l’effet de serre, en estimant les coûts de réduction des émissions de gaz à effet de serre associés. Les résultats montrent des bilans environnementaux particulièrement intéressants, mais des coûts de production encore élevés. Il en résulte des coûts à la tonne de CO2 évitée élevés, supérieurs à 100 € pour l’ensemble des technologies étudiées. Il existe toutefois une incertitude forte sur de nombreux paramètres. En outre, les gains potentiels de réduction des coûts liés au progrès technique, qui peuvent être importants, n’ont pas été évalués.
