据7月17日Trend报道，国际能源署(IEA)推出了一种新的在线工具，用于追踪石油和天然气相关的甲烷（一种主要且经常被忽视的温室气体）来源。

新的“甲烷追踪器”提供了最全面的全球甲烷排放情况，涵盖了70多个国家的8个工业领域。这一独特的新工具利用现有的最佳数据，为国际能源署提供了对当前石油和天然气甲烷排放量的最新估计。利用该技术可能实现的减排，并揭示了这一尚未得到充分开发的能源转换组成部分。国际能源署分析强调，全球石油和天然气行业的甲烷排放量可以在不产生净成本的情况下减少近一半。

目前，大气中甲烷的浓度是工业化前水平的2.5倍左右，而且还在稳步增加。由于甲烷是一种强有力的温室气体，这一增长对气候变化具有重要影响。能源行业是人类活动产生甲烷排放的最大来源之一。

国际能源署的预测显示，未来数年，石油，尤其是天然气，将在能源体系中扮演重要角色，即使是在与国际气候目标一致的高脱碳情景下。加强在供应链上减少甲烷排放的努力，是对二氧化碳减排的重要补充，而二氧化碳减排的主导因素是提高效率和部署清洁能源技术。

“油气行业面临着一个可选择的目标。他们可以避免近50%的甲烷排放，而不损害根本。这样做的长期气候效益与立即减少全球一半以上汽车的排放是一样的。”国际能源署执行主任法提赫?比罗尔(Fatih Birol)表示。

IEA launches new tool for tracking oil and gas-related methane emissions worldwide

The International Energy Agency has launched a new online tool that tracks oil and gas-related sources of methane, a major and often overlooked greenhouse gas, Trend reports citing IEA.

The new “methane tracker” offers the most comprehensive global picture of methane emissions, covering eight industry areas across more than seventy countries.

This new and unique tool provides the IEA’s most up-to-date estimates of current oil and gas methane emissions, drawing on the best available data. It also sets out the reductions that are possible using existing technology and sheds light on this underexplored component of energy transitions. IEA analysis has highlighted that global methane emissions from the oil and gas sectors could be reduced by nearly half at no net cost.

The concentration of methane in the atmosphere is currently around two-and-half times greater than pre-industrial levels and increasing steadily. This rise has important implications for climate change as methane is a potent greenhouse gas. The energy sector is one of the largest sources of methane emissions originating from human activity.

IEA projections suggest that oil and, in particular, natural gas will play important roles in the energy system for years to come, even under strong decarbonisation scenarios aligned with international climate goals. Reinforcing efforts to minimise methane emissions along their supply chains is an essential complement to the reductions in CO2 that are led by increased efficiency and deployment of clean energy technologies.

“The oil and gas sectors have an open goal in front of them. They can avoid close to 50 percent of their methane emissions without hurting the bottom line. Doing so would have the same long-term climate benefits as immediately eliminating emissions from more than half the cars on the road worldwide,” said Fatih Birol, the IEA’s Executive Director.
