India, the third-highest contributor, is projected to see emissions rise by 6.3% from 2017.
Global carbon emissions are set to hit an all-time high of 37.1 billion tonnes of CO2 in 2018.
The 2.7% projected global rise in 2018 has been driven by significant growth in coal use for the second year in a row, and sustained growth in oil and gas use.
This study has been done by the researchers at the University of East Anglia (UEA) and the Global Carbon Project.
10 biggest emitters in 2018 are China, U.S., India, Russia, Japan, Germany, Iran, Saudi Arabia, South Korea, and Canada.
