The Greenhouse gases are the key components for earth to maintain habitable temperature. Without GHS or CO2, earth would be too cold to live in. Green house gases are not harmful gas, but abundance of it makes it worse to the atmosphere. Recent times witnessed an increase in emission of co2 rate from the transportation, electricity usage and other deforestation effects produced by human society. This increases the earth's temperature at rapid scale. In 2018, the world saw about 36.57 billion metric tons of carbon dioxide emitted. This plot represents the global co2 emission from 1989 to 2018. we could see the emission rate has been increased exponentially. There is a slight drop in emission rate in 2012 which is due to recession.With the current population and economic growth, its expected to see rapid spike in the emission rate. The scatter plot show the linear relationship between the co2 emission and temperature rate.
This statistics show the co2 emission rate along with global and per capita share breakdown by country. In last 10 years, its observed China is the largest emitter of the co2 followed by united states, India, Russia and Japan. Although these countries has largest global share, considering population in mind, per capita sharing show arab countries like saudi arabia, united arab nations share a quite lot emission rate for their population size. Considering, cumulative co2 emission rate, united states leads the race over the China. In the last 40 years, CO2 emission rate had increased by 23.7 billion metric tons. In 2020, after covid-19 outbreak and lockdown activities led to a drop in emission rate. In March 2020, CO2 emission levels in india dropped for first time in last four decade.
