In this piece, we will take a look at the twenty countries that produce the most greenhouse gases. For more countries, take a look at 5 Countries That Produce the Most Greenhouse Gases.

The onset of the industrial revolution from the late 1700s to the early 1860s and then the onset of the second industrial revolution after the second world war has transformed the world in ways that would be unimaginable to populations that were alive just a couple of centuries ago. From the jet engine to the marvel of modern day mass production, human beings have transformed the world around them to suit their needs and improve their standard of living.

However, this development has come with its costs. The largest of these is perhaps global warming, which has led to an increase in the surface temperature of the Earth. This rise leads to a host of devastating climate events, such as droughts and a rise in sea levels, which end up causing a significant loss of life and property. According to statistics compiled by the National Aeronautics and Space Administration (NASA), global temperature has risen by 1.01 degrees Celsius since 1880, oceans have warmed by 337 zettajoules since 1955, global ice sheets are dropping by a massive 427 tons each year, and since January 1993, the sea has also risen by four inches.

These changes will create further turmoil in the world, according to a fresh study from the International Rescue Committee (IRC). Fueled by political instability and aided by climate change, the non governmental organization (NGO) estimates that since 2014, the number of people who need humanitarian assistance all over the globe has jumped by 81 million to a massive 339 million. It also believes that the gap between the funds needed for humanitarian assistance and the funds that are available now stands at $27 billion as of November 2022.

One key source of climate change is greenhouse gases. These are the byproducts of industrial processes and engines, and the main greenhouse gas is Carbon Dioxide. While it isn't toxic to humans, this gas envelops the Earth and prevents the surface heat from escaping the atmosphere - which then contributes to global temperature rises and warming. Oil companies remain the largest source of greenhouse gases, and some culprits that have been identified by research are Exxon Mobil Corporation (NYSE:XOM), Chevron Corporation (NYSE:CVX), and Saudi Arabian Oil Company (Saudi Aramco).

Our Methodology

We consulted the World Bank's Emissions Database for global Carbon Dioxide emissions to compile our list.  The data covers emissions up to 2019. For added flavor, emissions per capita are also provided to give readers a sense of emissions irrespective of the size of the countries listed.
