**Locals - Air - CH₄ & CO₂ - landfill gas - solid waste & pollutant - La Doña Juana Landfill**

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 in 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 [[27|solid waste]] sector currently accounts for over 20 per cent of Colombia's total CH₄ emissions (CATF, 2024).

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).

Policies frequently locate such [[19|pollution]] sources in impoverished communities such as Usme and Ciudad Bolívar, where [[14|locals]] are unfortunate enough to live near the [[09|La Doña Juana Landfill]] (Camargo, 2019).

**Air - CH₄**

CH₄ is a greenhouse gas whose global warming potential is 80 times than that of CO₂ over the first 20 years after release. CH₄ itself does not typically pose a direct health hazard, but at high concentrations it may limit O₂ availability.
Furthermore, as a precursor, CH₄ is a reactive gas that promotes the formation of tropospheric ozone, which is a hazardous atmospheric [[19|pollutant]] with potentially lethal effects on human health and public wellbeing (De et al., 2024).
