“…The increasing trend in the population is reported in census reports from the government, and the results of the study indicate that the MSW CH4 emission is positively correlated with the population growth and the total gross state domestic product (GDSP) with R 2 = 0.58 (Figure 6b). Similar observations are also reported by others as it is believed that high per capita income and GSDP/GDP (where GDP is gross domestic product) is the prime factor that indicates higher human activity and leads to the increased production of MSW [4]. …”

“…The results of current study suggest that there has been a continuous increase in CH 4 production by landfills in Delhi. During the period from 1999 to 2015, the amount of CH 4 increased from 31.06 Gg/yr to 65.16 Gg/yr, which is more than double the CH 4 composting and the anaerobic decomposition of wastes. Whereas changes in precipitation patterns might also affect the MSW management and make it difficult for the institutions involved in MSW management, in last few years, the population of Delhi has experienced a transition in terms of the developmental and industrial activity around the city, which has triggered rapid population growth and settlement in the city.…”

“…Municipal solid waste (MSW) is typically defined as the waste materials originating from domestic, commercial, and public areas such as gardens, street sweeping, and drain silts, which, in the long run, might cause environmental and public health problems [1][2][3]. Due to changes in lifestyle and increase in per capita income, the generation of MSW has increased, and its proper disposal and management has become a major challenge for government and non-government organizations [3,4]. The collection of MSW is challenging due to a lack of resources, improper infrastructure, lack of community participation, and awareness.…”

Abstract:The management of rapidly growing municipal solid waste (MSW) is one of the major challenges in developing countries. The current study also estimates the suitability of a site through a geographical information system using multi-criteria decision analysis (MCDA) for landfill sites in National Capital Territory (NCT). The results of the suitability index indicate that only 58.7 km 2 of the land is suitable for the construction of landfill sites, while 194.27 km 2 of the total area is moderately suitable. The existing three landfill sites that are currently functional and used by government organizations as landfills are found to be moderately suitable. A large fraction of MSW is disposed in landfills, which emit one third of the total anthropogenic methane (CH 4 ) and are considered an important contributor of Green House Gases (GHGs) to the atmosphere. Thus, there is a need for the proper estimation of GHG emission from landfills, specifically CH 4 , which contributes 20% of the GHGs that contribute to global warming. The current study aims to estimate the CH 4 emission from landfills in the NCT, Delhi, India using GHG inventory guidelines from the Intergovernmental Panel on Climate Change (IPCC). The CH 4 emission from landfills has doubled from 31.06 Gg/yr to 65.16 Gg/yr from 1999 and 2000 to 2015. The generation of CH 4 from MSW is strongly correlated (R 2 = 0.58) with the Gross State Domestic Product (GSDP), which is an indicator of wellbeing.

Methane accounts for 20% of the global warming caused by greenhouse gases, and wastewater is a major anthropogenic source of methane. Based on the Intergovernmental Panel on Climate Change greenhouse gas inventory guidelines and current research findings, we calculated the amount of methane emissions from 2000 to 2014 that originated from wastewater from different provinces in China. Methane emissions from wastewater increased from 1349.01 to 3430.03 Gg from 2000 to 2014, and the mean annual increase was 167.69 Gg. The methane emissions from industrial wastewater treated by wastewater treatment plants (EIt) accounted for the highest proportion of emissions. We also estimated the future trend of industrial wastewater methane emissions using the artificial neural network model. A comparison of the emissions for the years 2020, 2010, and 2000 showed an increasing trend in methane emissions in China and a spatial transition of industrial wastewater emissions from eastern and southern regions to central and southwestern regions and from coastal regions to inland regions. These changes were caused by changes in economics, demographics, and relevant policies.

Reliable inventory information is critical in informing emission mitigation efforts. Using the latest officially released emission data, which is production based, we take a consumption perspective to estimate the non‐CO2 greenhouse gas (GHG) emissions for China in 2012. The non‐CO2 GHG emissions, which cover CH4, N2O, HFCs, PFCs, and SF6, amounted to 2003.0 Mt. CO2‐eq (including 1871.9 Mt. CO2‐eq from economic activities), much larger than the total CO2 emissions in some developed countries. Urban consumption (30.1%), capital formation (28.2%), and exports (20.6%) derived approximately four fifths of the total embodied emissions in final demand. Furthermore, the results from structural path analysis help identify critical embodied emission paths and key economic sectors in supply chains for mitigating non‐CO2 GHG emissions in Chinese economic systems. The top 20 paths were responsible for half of the national total embodied emissions. Several industrial sectors such as Construction, Production and Supply of Electricity and Steam, Manufacture of Food and Tobacco and Manufacture of Chemicals, and Chemical Products played as the important transmission channels. Examining both production‐ and consumption‐based non‐CO2 GHG emissions will enrich our understanding of the influences of industrial positions, final consumption demands, and trades on national non‐CO2 GHG emissions by considering the comprehensive abatement potentials in the supply chains.
