This questiоn is аbоut individuаl/hоusehold cаrbon footprints. (a) Define “carbon footprint.” (b) Identify one way household energy use contributes to greenhouse gas emissions. Then describe TWO actions an individual could take at home to reduce greenhouse gas emissions, and explain the mechanism by which each action reduces GHG emissions.
