To a certain extent, the concept of "best practice" can be understood as "best policy measures" or (in a broader context) "best policy and measures" to secure the recovery and use of coal associated gases, primarily coal mine methane (CMM) and coalbed methane (CBM), which are obtained through pre-mine drainage at active coal mines. This report suggests considering similarities between different countries’ successful polices and institutional choices that have led to significant reductions in CMM emissions.
