Even assuming that CO2 is some sort of wonder gas as climate alarmists like to claim, the percentage of total CO2 from the use of fossil fuels is much too low to be the cause of global warming, according to this detailed research.

After 1750 and the onset of the industrial revolution, the anthropogenic fossil component and the non-fossil component in the total atmospheric CO2 concentration, C(t), began to increase, says Climate Change Dispatch.
Despite the lack of knowledge of these two components, claims that all or most of the increase in C(t) since 1800 has been due to the anthropogenic fossil component have continued since they began in 1960 with “Keeling Curve: Increase in CO2 from burning fossil fuel.”
Data and plots of annual anthropogenic fossil CO2 emissions and concentrations, C(t), published by the Energy Information Administration, are expanded in this paper.
Additions include annual mean values in 1750 through 2018 of the C14 (Carbon-14) specific activity, concentrations of the two components, and their changes from values in 1750.
The specific activity of C14 in the atmosphere gets reduced by a dilution effect when fossil CO2, which is devoid of C14, enters the atmosphere. We have used the results of this effect to quantify the two components.
All results covering the period from 1750 through 2018 are listed in a table and plotted in figures.
These results negate claims that the increase in C(t) since 1800 has been dominated by the increase of the anthropogenic fossil [fuel] component.
