2022年9月,北溪天然气管道发生泄漏,大量甲烷被释放到大气中。一个由法国原子能和替代能源委员会(CEA)两个团队参与的国际工作组,现已确定了此次泄漏的甲烷总量。
据测算,泄漏的甲烷总量约为46.5万吨。这相当于全球每年人为甲烷排放总量的0.1%。研究指出,这是有记录以来单次瞬时事件中释放甲烷量最大的一次。

An international research team, including two groups from France's CEA (Atomic Energy and Alternative Energies Commission), has quantified the massive methane release from the September 2022 Nord Stream pipeline ruptures. Their analysis concludes that approximately 465,000 tonnes of methane were emitted into the atmosphere.
This event constitutes the largest single-point, transient release of methane ever measured. To provide context, the estimated volume represents about 0.1% of total annual anthropogenic emissions of this potent greenhouse gas. The findings underscore the significant climate impact of major infrastructure failures, as methane has a global warming potential many times greater than carbon dioxide over a 20-year period.
Un groupe de travail international associant deux équipes du CEA détermine la quantité de méthane relâchée dans l’atmosphère en septembre 2022 par les fuites des gazoducs Nord Stream. Estimée à 465 000 tonnes, soit 0,1% des émissions anthropiques annuelles de ce puissant gaz à effet de serre, il s’agit de la plus grande quantité de méthane jamais mesurée pour un seul évènement transitoire.

Nord Stream — natural gas pipeline system between Russia and Europe, based in the Baltic Sea route.
Monitor — important for energy transition, emissions monitoring, and pipeline security, but not an immediate market-moving event.
