After declining in 2016, CO2 emissions went back up in 2017. According to estimates from the Global Carbon Project, emissions increased by almost 600 million tonnes, ending up at 41.47 billion tonnes. Emissions had actually decreased in 2016 after flattening out over the last few years, bringing hope that we had finally reached peak carbon pollution, but it was not to be. Still, emissions have only edged up slightly in five years, so there is hope that the curve will finally start to bend downwards. Just as the curve had flattened mostly because of decreasing coal use in China, the Middle Kingdom was also responsible for the increase, with emissions going up by 3.5%, including 3% growth in coal emissions. China has promised to peak its emissions before 2030, but not quite yet it seems. Let’s hope they do it soon.
