Decomposing food waste is releasing thousands of tonnes of planet-warming methane gas at landfills in Buenos Aires, Delhi, Mumbai, and Lahore, according to new research.

With about 570 million tonnes of the greenhouse gas emitted every year from both industrial and natural processes, the concentration of methane in the atmosphere has been increasing at a record pace, according to the U.S. National Oceanic and Atmospheric Administration.

High-resolution satellite images snapped in 2020 revealed the methane was coming from upwind landfills in the Argentine capital of Buenos Aires, the Indian cities of New Delhi and Mumbai, and Pakistan’s second-largest city of Lahore, according to the study published recently in the journal Science Advances.
