Contextualization: Since the Kyoto protocol and the Paris Summit, the reduction of greenhouse gases, GHG, caused by anthropic activity, has become vitally important in the world, given the critical emission indicators with harmful effects on the climate. 

Knowledge gap: Within this panorama, preliminary researches does not agree on which fuel generates the lowest CO2 emissions: diesel or biodiesel. 

Purpose: For this reason, and seeking to provide information to propose sustainable energy alternatives from substitutes for fossil fuels, it was necessary to quantify and evaluate CO2 emissions from diesel engines, for which purpose, the experiment was carried out with the purpose of use commercial diesel  and biodiesel, and determine their CO2 emissions, for this a compression engine from a power plant was used, with fixed factors such as the amount of fuel to be used established at 100 grams. 

Methodology: The experiment was statistically supported by a factorial design of two factors: type of diesel with two levels and power generated with three levels, and the joint effect that these factors produce on CO2 emission was determined. For this, the motor was subjected to the execution of three jobs related to three generated powers: 0.5kW-1.0kW-1.5kW; which caused for each power level, different flows or consumption of fuel and air, and different CO2 emissions. 

Results and conclusions: The results indicate that: using any fuel, the air/fuel ratio is lower and the molar fraction of CO2 is higher when more work is done; the experiment showed that the molar fraction of B10 is greater than that of B100: 0,15 and 0,13, respectively, so it cannot be generalized that the higher CO2 emission is caused by commercial diesel. The greater or lesser emission depends on the chemical composition of the fuel.
