据今日油价网站8月14日消息 世界上一些最大的石油和天然气公司已经开始出售他们所谓的碳中和石油和液化天然气，因为买家越来越关注全球能源供应的环境认证。

　　过去几年，几家主要石油公司宣布销售碳中和液化天然气货物。随着全球向净零排放迈进，这一趋势只会变得更加强劲。

　　但碳中和，尤其是对于液化天然气货物而言，乍一看并不如此。

　　人们可能会认为，碳中和这一术语意味着天然气生产、液化和运输过程中产生的排放已经通过碳捕获等技术得到了抵消。

　　事实上，这种碳中和状态是由液化天然气买家和卖家为参与世界其他地方（实际上是任何地方）的减排项目而付费实现。

　　石油和天然气公司购买经过验证的碳信用额度，主要用于基于自然的解决方案，以防止某处的森林砍伐，这种方法实际上并没有减少液化天然气货物的碳排放。如果他们投资的减排项目没有实施，它只是为了通过防止潜在排放来抵消这些排放。

　　彭博社在一篇调查性文章中报道，减排项目提供商的分析师和代表表示，这些碳抵消方法无法实现净零目标，而且难以计算。

　　Is Carbon Neutral Oil Really Possible?

　　Some of the world’s biggest oil and gas firms have started to sell what they say is carbon-neutral oil and liquefied natural gas (LNG) as buyers increasingly look at the environmental credentials of global energy supply.

　　Several major oil firms have announced sales of carbon-neutral LNG cargoes in the past few years. The trend is only set to become stronger amid the global push toward net-zero emissions.

　　But ‘carbon neutral’, especially for LNG cargoes, is not what it looks like at first glance.

　　One would think that the term carbon neutral implies that the emissions generated from the production, liquefaction, and transportation of the gas have been offset during those processes with technologies such as carbon capture, for example.

　　In reality, this “carbon-neutral” status is being achieved by LNG buyers and sellers paying for participation in emissions-reduction projects elsewhere (actually anywhere) in the world.

　　Oil and gas firms buy verified carbon credits, mostly for nature-based solutions, to prevent deforestation somewhere. This approach doesn’t actually reduce the carbon emissions from an LNG cargo; it just aims to offset those emissions with the prevention of potential emissions if the emission-reduction project they are invested in wasn’t implemented.

　　Analysts and representatives of providers of emission-reduction projects say that these carbon-offsetting approaches do not advance net-zero goals and are difficult to calculate, Bloomberg reports in an investigative article.
