The report starts by taking stock of the state of mitigation. In fact, it is more a question of a failure to mitigate. Global emissions of all greenhouse gases combined have increased by 11% compared to 2010. Their volume (59 GTCO2eq in 2018) is larger than ever in human history. Between 2010 and 2018, the rate of increase slowed down somewhat: 1.3% per year, compared to 2.3% during the previous decade.
