Urbanisation has significantly transformed societies and economies worldwide. In Asia and the Pacific, the urban population increased from 34 per cent in 1960 to 58 per cent in 2024, growing at an average of 2.4 per cent annually, compared to the global average of about 2.8 per cent. At the same time, urbanisation has led to an increase in methane emissions from the waste sector. Over the past fifty years, global methane emissions from the waste sector have grown at an average rate of 1.25 per cent each year. On a global scale, in 2024, the solid waste sector remains the largest source, accounting for about 60 per cent. In Asia and the Pacific, waste production is expected to rise, with total methane emissions reaching 25 million tonnes in 2024. Conversely, the main sources are wastewater, contributing 15,466 ktCH4 (61 per cent), and solid waste, adding 8,558 ktCH4 (34 per cent). This technical paper concludes with five strategic pillars to help policymakers turn global methane reduction commitments into effective urban measures.
