Global greenhouse gas emissions 1970-2023

In 2023, global greenhouse gas (GHG) emissions increased by two percent year-over-year to reach a new record high of 53 billion metric tons of carbon dioxide equivalent (GtCO₂e). This represents a more than 60 percent rise in GHG emissions since 1990. The continuous growth in emissions has significant implications for global climate patterns and environmental stability.Rising global temperaturesGHG emissions from human activities are contributing to global warming. In 2023, the global land and ocean surface temperature stood at 1.19 degrees Celsius above the 20th century average, the largest recorded deviation in history. This temperature increase is part of a consistent pattern of positive temperature anomalies observed since the 1980s, highlighting the long-term warming effect of increased GHG accumulation in the atmosphere, particularly carbon dioxide.Biggest contributors to GHG emissionsGlobally, the power industry was responsible for 15 GtCO₂e in 2023, accounting for approximately 28 percent of global GHG emissions. This sector's emissions were nearly double those of the global transportation sector, the second-largest emitter. Coal-fired generation is the main contributor to power sector emissions. This is particularly the case in Asian countries, where there is a high reliance on this energy source. The Asia-Pacific region was the largest contributor to global CO₂ emissions in 2023, producing 18.9 GtCO₂ from energy use alone.

于2023年，全球温室气体（GHG）排放量同比增长两成，达到创纪录的530亿公吨二氧化碳当量（GtCO₂e）。相较于1990年，温室气体排放量已增长超过60%。排放量的持续增长对全球气候模式和生态环境稳定性产生了深远影响。全球气温的上升由于人类活动的温室气体排放，正加剧全球变暖。2023年，全球陆地和海洋表面温度较20世纪平均值高出1.19摄氏度，创下历史最大偏差记录。这一温度上升是自1980年代以来持续观测到的正温度异常现象的一部分，凸显了大气中温室气体，尤其是二氧化碳积累增加对长期气候变暖效应的影响。温室气体排放的主要贡献者全球范围内，电力行业在2023年排放了15 GtCO₂e，约占全球温室气体排放量的28%，其排放量几乎是全球交通行业的两倍，后者为第二大排放源。燃煤发电是电力行业排放量的主要来源，尤其在亚洲国家，这些国家对该能源资源有高度依赖。在2023年，仅能源使用就使亚太地区成为全球二氧化碳排放量最大的贡献者，产生了18.9 GtCO₂。
