Many countries introduced scrapping programs in the 1990s, partly legitimized by environmental impact reductions. However, reducing the age of the current car fleet may result in an increase of life-cycle carbon dioxide emissions. This will probably also be true for cars to be produced in the future unless fuel efficiency of new cars improves much faster than the historical trend indicates. Reducing the age of gasoline-fueled cars without a catalytic converter will reduce both life-cycle nitrous oxides and volatile organic compounds emissions, but is less cost-effective than fitting catalytic converters on these cars. In any case, the influence of a car's lifetime on life-cycle nitrous oxides and volatile organic compounds emissions will be reduced in the near future.
