Landfill management practices and organic diversion were highlighted in a handful of studies. detected very large CH4 emissions from a landfill in Los Angeles, which were attributed to a specific management practice. The landfill operator was placing several inches of daily cover overtop of fresh waste to minimize odor complaints from residents downwind, but this practice -which did not include peel-back before new waste was added -created pockets of CH4 that the landfill would intermittently "burp" into the atmosphere. notified the landfill operator of the emissions and reductions were verified with follow up aerial measurements after the operator changed the practice and improved gas capture from this area of the landfill. The reductions achieved at this landfill were also verified in regional-level measurements . These examples emphasize that measurement is a powerful tool to identify mitigation opportunities and verify emissions reductions.
