11. Saudi Arabia
Emissions – 494,822.17 Ktons CO2
The country with the world’s largest oil reserves and an economy almost exclusively based on the export of fossil fuels, Saudi Arabia holds a controversial position regarding climate change. Over the years, it was accused of trying to block anti-climate change measures, mostly in order to protect its economy. More recently, however, the country announced that it plans to diversify its economy in order to help combat climate change. The government set its target at 130 million tonnes of carbon emissions by 2030, which means impressive measures are to be taken in the next 14 years in order to reach these numbers.
