15 Most Polluting Companies in the World

In this piece, we will take a look at the fifteen most polluting companies in the world.

Global warming is one of the most pressing challenges faced by the world today. Greenhouse gas emissions, an ugly consequence of the cost of industrialization and development, end up raising the planet’s temperature. This, in turn, changes the climatic ecosystem and leads to more devastating events that end up disrupting lives.

According to the U.S. Environmental Protection Agency (EPA), Carbon Dioxide takes up the largest chunk of greenhouse gas emissions. Between 1900 and 2014, global carbon emissions jumped from roughly 500 million metric tons to a whopping 10,000 metric tons, for an absolutely shocking 1,900% increase. China and the U.S. have accounted for roughly half (45%) of these emissions, and the most polluting industries are energy production and agriculture and related sectors. However, the agriculture sector also removes Carbon Dioxide from the atmosphere, with an estimated 20% of its total emissions taken back.

A striking example of the consequences of global warming came in the form of floods in Pakistan earlier this year. Spurred by the rise in temperature and poor construction planning in the South East Asian country, the floods are estimated to have taken at least 1,700 lives and caused up to $40 billion in damage, alongside displacing another 7.9 million people.

Greenhouse gases make their mark on the planet by increasing global temperature, as they blanket the Earth and stop the heat from the Sun from leaving. Their impact is striking, as between 1880 and 1981, Earth’s temperature increased by 0.14 degrees Fahrenheit during 100 years; but between then and 2022, it has increased by more than double, or by 0.32 Fahrenheit. Europe has seen the greatest temperature increase during this time period, with levels that match the Eastern coast of the United States.

Today’s piece will focus on the firms that have emitted the largest amounts of carbon dioxide so far. The biggest contributors are oil companies, including Exxon Mobil Corporation (NYSE:XOM), Chevron Corporation (NYSE:CVX), and Saudi Arabian Oil Company (Saudi Aramco).
