Emissions Estimates

Waste Sector

The Waste Sector contributed to about 4% of India's total GHG emission in 2018. Municipal solid waste, domestic wastewater and industrial wastewater are the key sources of GHG emissions in the sector. Methane (CH4) is produced and released into the atmosphere as a by-product of the anaerobic decomposition of solid waste and when domestic and industrial wastewater is treated or disposed anaerobically. Nitrous oxide (N2O) emissions occur due to protein content in domestic wastewater.

The waste sector emission estimates have been prepared through a detailed disaggregated estimate of India's GHG emissions from 2005-2018 resulting from disposal and decay of municipal solid waste, and from the treatment and discharge of urban domestic wastewater and industrial wastewater.

The lead sector partner for Waste Sector Emissions Estimates is ICLEI South Asia.
