Among the main culprits of climate change is China, the country that has contributed the most to global warming with its emissions of carbon dioxide (CO2), the main greenhouse gas. China released 31% of the total CO2 into the atmosphere in 2021, equivalent to about 12,466.3 megatons. This research conducted a characterization of the variables CO2 emissions and vehicle fleet, a normality test was applied to the data using Shapiro Wilk analysis, a Spearman correlation test that resulted in a strong correlation of r= 0.986; which means that there is a very strong positive correlation between the two variables. This implies that when one variable increases, the other also tends to increase, and vice versa. A future projection was made using the least squares model, year by year, from 2024 to 2030, with the result that in 2024 CO2 emissions will be 13471.3 Mt and these emissions will increase until 2030 up to 15,419.7 Mt, which puts at risk the world environmental goals of reducing CO2 emissions and global temperature of the planet by less than 1.5 degreesC.
