The UN environment agency warns that rotting food waste is a major source of greenhouse gas emissions. It says food waste can account for up to 10% of total global greenhouse gas emissions, adding that this is roughly five times more than emissions from the entire aviation sector.
The outlets cite the same UN-linked assessment, emphasizing that food waste represents a significant and often overlooked contributor to the climate crisis. Guyana Chronicle frames the issue as a key driver if it is not addressed, while AllAfrica focuses on the comparison to aviation to highlight the scale of emissions. Both accounts present the warning as coming from the UN Environment Programme (UNEP) and underscore the link between unmanaged food waste and climate impacts.
Across the coverage, the central points align: rotting food waste is responsible for a large share of emissions, and its impact can exceed that of air travel when compared on a global basis.
