Global CO emissions for 2022 increased by 1.5% relative to 2021 (+7.9% and +2.0% relative to 2020 and 2019, respectively), reaching 36.1 GtCO. These 2022 emissions consumed 13%-36% of the remaining carbon budget to limit warming to 1.5 °C, suggesting permissible emissions could be depleted within 2-7 years (67% likelihood).
2022年全球一氧化碳排放量相对于2021年增加了1.5%（相对于2020年和2019年分别增加了7.9%和2.0%），达到361亿吨一氧化碳。这些2022年的排放量消耗了将升温限制在1.5摄氏度的剩余碳预算的13%-36%，这表明允许排放量可能在2-7年内耗尽（可能性为67%）。
