Any gas which absorbs and emits radiant energy within the thermal infrared range is known as a greenhouse gas. These gases are responsible for the greenhouse effect. A few of the greenhouse gases which exist within the Earth's atmosphere are carbon dioxide, water vapor, methane and nitrous oxide. The various factors, which have led to the sudden increase in the emission of greenhouse gases are deforestation, soil erosion, changes in land use, and combustion of fossil fuels. The effects of greenhouse gases can be mitigated through different methods, which are broadly classified as natural processes and negative emissions. Natural processes generally make use of a natural sink to remove the greenhouse gases from the atmosphere. Negative emission technologies aim to convert and store carbon dioxide as geologic formations. This book studies, analyzes and upholds the pillars of the mitigation of greenhouse gas emissions and its utmost significance in modern times. The topics included in this book are of utmost significance and bound to provide incredible insights to readers. The book is appropriate for students seeking detailed information in this area as well as for experts.
