India's contributions to climate change and emissions 1850-2021
India accounted for almost 20 percent of the global population in 2021, but just seven percent of global greenhouse gas emissions that year. India's contributions to historical carbon dioxide emissions are even lower, at just four percent. Overall, India is estimated to be responsible for around five percent of global warming since 1850. By comparison, the United States, which represented just four percent of the global population in 2021, is the biggest contributor to climate change, with approximately 17 percent of warming linked to the North American country since 1850.
