1 Atmospheric CO 2 is part of the global carbon cycle, and therefore its fate is a complex function of geochemical and biological processes. Some of the excess carbon dioxide will be absorbed quickly (for example, by the ocean surface), but some will remain in the atmosphere for thousands of years, due in part to the very slow process by which carbon is transferred to ocean sediments.

Electrification of the vehicles is of course a good solution to replace fossil fuel for mobility. This path is however penalized by the density of the electricity storage in the batteries. Fossil fuels are a finite resource, hence they should be replaced by bio-based fuel equivalent. This however requires lots of land that may compete with the food production. CO2 capture is also an alternative, if one can capture with limited energy penalty, and converts captured CO2into fuels using renewable electricity. In the year 2014, CO2 emissions due to human activities accounted for about 65% of greenhouse gas emissions globally (IPCC, 2014). In 2016, transportation sector was accountable for about 28 percent of CO2 emissions in USA (United States Environmental Protection Agency, 2016).
