| The [[09|La Doña Juana Landfill]] is emitting high levels of CH₄, making a significant contribution to global warming (Greenpeace Colombia, 2024). | The [[09|La Doña Juana Landfill]] is emitting high levels of CH₄, having a significant impact on global warming (Greenpeace Colombia, 2024). |

| Waste within landfills gradually decomposes as it accumulates. In the absence of proper management, the physical and chemical conditions within landfills promote anaerobic decomposition, leading to CH₄ emissions. The release of methane into the [[01|air]] accelerates the process of climate change (De et al., 2024). CH₄ released during the decomposition of solid waste sector currently accounts for over 20 per cent of Colombia's total CH₄ emissions (CATF, 2024). | Waste within landfills gradually decomposes as it accumulates.

| The environmental risks of landfills extend beyond CH₄ emissions. As waste decomposes, landfills also emit CO₂, which is another greenhouse gas contributing significantly to climate change as CH₄ (De et al., 2024). | The environmental risks of landfills extend beyond CH₄ emissions.
