Following record-level declines in 2020, near-real-time data indicate that global CO emissions rebounded by 4.8% in 2021, reaching 34.9 GtCO. These 2021 emissions consumed 8.7% of the remaining carbon budget for limiting anthropogenic warming to 1.5 °C, which if current trajectories continue, might be used up in 9.5 years at 67% likelihood.
在经历了2020年创纪录的下降之后，近实时数据显示，2021年全球二氧化碳排放量反弹了4.8%，达到349亿吨二氧化碳。2021年的这些排放量消耗了将人为变暖限制在1.5摄氏度的剩余碳预算的8.7%，如果目前的趋势继续下去，剩余碳预算可能在9.5年内以67%的可能性耗尽。
