Car sharing is emerging as a practical way for urban households to cut both transport costs and carbon emissions. In Australian cities like Sydney and Melbourne, services such as GoGet and Flexicar provide access to vehicles without the fixed costs of ownership, which can run about $8,000 per year before fuel. The City of Melbourne estimates each shared car removes up to nine privately owned cars from the road, and members reduce car use by up to 50%. Environmental benefits depend on households actually giving up a car or avoiding a second one. Most fleets still rely on petrol or diesel, though some providers offer hybrids or EVs. The economics of electric car share fleets remain tight, and state rebates or free charging at bays could help. For households that mostly walk, cycle, or use transit but need a vehicle occasionally, sharing can be a solid step toward lower emissions and lower spending.
