The global trend in CO2 emissions since 2000 indicates an almost constant increase in per capita emissions. The last registered value is 4996 million tons per capita, distributed in the different areas of industry, electricity, agriculture, transport, etc. The increase in CO2 emissions not only implies environmental problems due to the greenhouse effect caused by CO2, but it will also generate health problems for people exposed to said pollution. In Bolivia, annual gasoline consumption is 9.2 million barrels of gasoline per day, which translates into the generation of approximately 3,443.3 tons of CO2 per year. Analyzing the high percentage of this greenhouse gas generated and the problems that its accumulation generates for the environment and the population, it is essential to analyze ways to trap it and transform it into useful alternative products. One of these products is ethanol, which can be used as fuel in alcohol / gasoline blends. There are several studies on the chemical transformation of CO2 using different processes and catalysts, many of them very expensive and produced under drastic conditions (high pressures and temperatures). The first phase of the project is aimed at studying the experimental parameters to obtain ethanol from CO2 by electrolysis and using copper as a catalyst.
