“…Nevertheless, active mitigation of landfill emissions in developed nations is a long‐established and effective priority and thus not the focus of the discussion here. In contrast, in many tropical nations, landfill methane emissions are wholly uncontrolled and are characteristically high, especially in India (e.g., Ghosh et al, ; Kumar et al, ; Lobert et al, ). Even in Kuwait, the landfill is a major source (al‐Shalaan 2019) (Figure ).…”

The atmospheric methane burden is increasing rapidly, contrary to pathways compatible with the goals of the 2015 United Nations Framework Convention on Climate Change Paris Agreement. Urgent action is required to bring methane back to a pathway more in line with the Paris goals. Emission reduction from “tractable” (easier to mitigate) anthropogenic sources such as the fossil fuel industries and landfills is being much facilitated by technical advances in the past decade, which have radically improved our ability to locate, identify, quantify, and reduce emissions. Measures to reduce emissions from “intractable” (harder to mitigate) anthropogenic sources such as agriculture and biomass burning have received less attention and are also becoming more feasible, including removal from elevated‐methane ambient air near to sources. The wider effort to use microbiological and dietary intervention to reduce emissions from cattle (and humans) is not addressed in detail in this essentially geophysical review. Though they cannot replace the need to reach “net‐zero” emissions of CO2, significant reductions in the methane burden will ease the timescales needed to reach required CO2 reduction targets for any particular future temperature limit. There is no single magic bullet, but implementation of a wide array of mitigation and emission reduction strategies could substantially cut the global methane burden, at a cost that is relatively low compared to the parallel and necessary measures to reduce CO2, and thereby reduce the atmospheric methane burden back toward pathways consistent with the goals of the Paris Agreement.

“…MSW landfills emit large amounts of methane, which means that efficient methane recovery is an effective method of the reduction of GHG emissions. Ghosh et al estimated the GHG emissions from landfill sites in Delhi, India, and they pointed out that effective CH 4 recycling is a sustainable waste management scheme [25]. Besides, Carbon dioxide capture and recycling methods such as the production of biobased products through microalgae can be used as effective means of reducing GHG emissions [26,27].…”

“…The fifth chapter of the National GHG Inventory prepared by the Intergovernmental Panel on Climate Change (IPCC) of the United Nations lists the calculation methods for GHG emissions from waste disposal [41]. Many researchers have followed the guidance of the IPCC in the calculation of GHG emissions from MSW [9,20,22,23,25]. LCA is regarded as an effective method to quantify product sustainability [42].…”

The Chinese government is committed to ensuring separation of municipal solid waste (MSW), promoting the integrated development of the MSW management system with the renewable resource recovery system, and achieving construction of ecological civilization. Guided by the methods in Intergovernmental Panel on Climate Change (IPCC) guidelines, the greenhouse gas (GHG) emissions under five waste disposal scenarios in Beijing under the life cycle framework were assessed in this research. The study included collection and transportation, as well as three end disposal methods (sanitary landfill, incineration, and composting), and the emission reduction benefits of electricity generation from incineration and recycling of renewable resources were taken into account. The results show that an emission reduction benefit of 70.82% could be achieved under Scenario 5 in which kitchen waste and recyclables are sorted and recycled and the residue is incinerated, and the selection of the optimal strategy was not affected by changes in the separation rate. In addition, landfill would emit more GHG than incineration and composting. The results of this study are helpful for the government to make a decision on MSW management considering the goal of GHG emission reduction.
