Until recently, global CO2 emissions from fossil fuels had levelled off, but estimates from the Global Carbon Project (GCP) suggest that this is all going to change, with global emissions set to grow by around 2%.
Those emissions had increased by only a quarter of a percent from 2014 to 2016.
The top 10 largest emitter countries account for nearly 70% of the world total.
