在全球气候治理的议题中，相较于公众更为熟知的二氧化碳，甲烷减排问题同样紧迫。甲烷是 仅次于二氧化碳的第二大温室气体，其增温效应高出二氧化碳数十倍。全球范围内的甲烷正在以 几十年内最快的速度增长（1），并在2023年创下排放新高（2）。 在我国，甲烷排放主要来自能源活动、农业活动和废弃物管理。能源活动是甲烷排放的最大来 源，而煤矿甲烷更是占到能源部门甲烷的87%（3）。 在中国的能源版图中，山西省无疑是一块重地：山西煤炭储量占全国四分之一，煤层气（瓦 斯）探明储量居全国之首。这个"因煤而兴"的传统能源大省，如今面对一个更隐秘的黑色难题—— 甲烷减排。 甲烷（CH₄）是瓦斯的主要成分，在煤炭开采时从煤层中逸出。山西的甲烷排放就主要来自煤 矿作业，当地每年煤矿释放的甲烷，相当于2亿吨二氧化碳当量，占全国总排放量的近三成 （4）。 这一政策空白终于在2024年12月被填补：新修订的《煤层气（煤矿瓦斯）排放标准》，要求甲 烷体积浓度高于8%且抽采纯量高于10立方米每分钟的煤矿瓦斯禁止排放，此前这一数值为30%。 这一变化意味着，过去大量直接排放的低浓度瓦斯，如今已被纳入约束范畴。此前有专家表示， 新标准修订后，每年可额 ...
