2. United States
Emissions – 5,334,529.74 Ktons CO2
Despite whatever conspiracy theorists want you to believe, global warming is real and it’s happening everywhere in the world and the United States is one of the countries that holds most of the responsibility. In fact, in 2014, it put over 5.3 billion tonnes of CO2 into the atmosphere. For comparison’s sake 28 European Union member states only generated 3.4 billion tonnes of CO2 in the same year.
As if it finally awakened from a deep sleep, the United States has put forward an ambitious proposal, seeking to cut carbon dioxide emissions by 32 percent from 2005 levels by 2030, increasing its renewable energy usage by 30 percent by the same year.
