Over the last couple of centuries, there has been a steady increase in the concentration of greenhouse gases (GHGs) in the atmosphere, enhancing global warming. Methane is one of the most important GHG contributing to the present day global warming. As CH4 is far more potent than CO2 in radiative forcing, CH4 emissions abatement and absorption is considered as a major option to restrict global climate change. Technologies pertaining to negative emissions aim particularly to capture carbon including CH4, in the atmosphere. Technologies for CH4 removal include photocatalysts, metal catalysts associated with zeolites and porous polymer networks, biological CH4 removal, industrial approaches and approaches for managing soils in agriculture, etc. It is noteworthy to mention that negative emissions technologies should be viewed as complementary to conventional decarbonization methods and not a substitute. Today, most of the negative emission technologies are in the developing stage, which needs further research, technological innovations, investment, incentives and policy guidance. In due course of time, these technologies are expected to play a vital role in climate change mitigation.
