A greenhouse gas is described as a gas that contributes to the greenhouse effect by absorbing infrared radiation. Knowledge of the capture of greenhouse gases, usage, reduction and storage is necessary for solving matters like global warming and climate change that occur due to greenhouse gases. This book presents an overview of recently developed techniques, methods, and strategies regarding the above mentioned topic. It also includes discussions on the reduction of greenhouse gases by policy management, alternative energy sources, mitigation schemes and an extensive review of the geological storage monitoring techniques.
