摘要：Greenhouse gases are: carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulfur hexafluoride. In December 2020, the European Council approved a new target for reducing greenhouse gas emissions by 2030 and a net domestic emission reduction of at least 55% compared to 1990, and climate neutrality for 2050. Careful monitoring of emissions is needed to achieve these goals. The paper aims to evaluate and compare the carbon dioxide emission coefficient, in the case of burning different fuels: petroleum fuels and biofuels. The calculation model was developed based on the mathematical relationships taken from specific publications. Kerosene, Liquiefied Petroleum Gas, Gasoline COR 95 Euro 5 and Diesel Euro 5 are the petroleum fuels used in the study. The used biofuels are: Bioethanol, Biobuthanol, Biodiesel (soybean) and Biodiesel (rapeseed). The results provide data on the amount of CO2that reaches into the atmosphere. Based on the information obtained, a fuel ranking can be made and decisions can be taken regarding their choice.
