Microbial degradation of organic matter in landfills generates methane, a potent greenhouse gas. Here, Grégoire et al. use metagenomic approaches to study microbial methane cycling in waste landfilled over 39 years, highlighting the importance of specific microbial lineages and methane oxidation in the absence of oxygen.
