Global carbon emissions are set to hit an all-time high of 37.1 billion tonnes of CO2 in 2018, according to researchers at the University of East Anglia (UEA) and the Global Carbon Project.
India, the third-highest contributor, is projected to see emissions rise by 6.3% from 2017. The 2.7% projected global rise in 2018 has been driven by appreciable growth in coal use for the second year in a row, and sustained growth in oil and gas use, according to the study that was published simultaneously Wednesday in several leading scientific journals.
This week, representatives from more than 190 countries have begun discussions at the UN Climate Change Conference (COP 24) in Katowice, Poland, on ways to equitably cut carbon emissions.
Second year in a row
CO2 emissions have now risen for a second year, the study’s authors say, after three years of little to no growth from 2014 to 2016. The rise in 2017 was 1.6%.
The 10 biggest emitters in 2018 are China, U.S., India, Russia, Japan, Germany, Iran, Saudi Arabia, South Korea, and Canada. The EU as a region of countries ranks third. China’s emissions accounted for 27% of the global total, having grown an estimated 4.7% in 2018 and reaching a new all-time high.
Emissions in the U.S., which has withdrawn from its commitment to the Paris Agreement, account for 15% of the global total, and look set to have grown about 2.5% in 2018 after several years of decline.
