Climate change is primarily driven by CO₂ emissions. Achieving the Paris Agreement's target of limiting global warming to 1.5 °C requires not only reducing current emissions but also removing existing CO₂ from the atmosphere. This study explores the potential of Direct Air Capture combined with utilisation (DAC-U) at a household scale. Using Life Cycle Assessment (LCA), the research evaluates the environmental and economic feasibility of a small-scale DAC-U system that converts CO₂ into household fuel and generates carbon credits. If environmentally and economically viable, decentralised DAC-U units could provide a socially acceptable means for households to contribute to carbon neutrality.
