The evolution of emissions by country
The following charts show how the composition of the world’s carbon emitters has changed over the past 20 years. It’s no surprise to see that China’s industrialisation has been a game-changer; as the US, Japanese and European share shrinks on a relative basis, Asia’s biggest economy now accounts for almost a third of global emissions, more than doubling its proportion since 2003.
India’s contribution is also of note, rising to 7 percent of global emissions from 4 percent. Overall carbon emissions have increased to 37 billion tonnes from 27 billion tonnes 20 years earlier.
These trends highlight the importance of US-China climate talks, which resumed late last year. US climate envoy John Kerry said in Davos last week that he was hopeful about a breakthrough.
