According to the infographic, the global pandemic of Covid-19 has resulted in a massive reduction of CO2 emissions, i.e., by nearly 2 gigatonnes. This figure is almost equal to the total increase in the emission of CO2 since 2013. The most significant decrease in the CO2 emissions is due to the lesser oil consumption the entire year, which was due to the banned transportation for more than half a year. The lesser oil use resulted in 1.2 gigatonnes or 1.2 billion tonnes reduction in the global carbon emissions.
As revealed by the chart, the demand for global energy, which leads to global carbon emission, was accelerated by the United States and China the most in 2017 and 2018 by 0.5 and 0.8 gigatonnes, respectively. Whereas the graph was flattened in the years 2014, 2015, 2016, and 2019. The reductions were never as significant as they were in 2020 due to the global pandemic crisis.
Now that the world is being provided with vaccines against the Covid-19, these reductions are doubted to stay this way for a longer time.
