The average 2006 disposable nappy would result in a global warming impact of approximately 550kg of carbon dioxide equivalents used over the two and a half years a child is typically in nappies. The global warming impact from disposable nappies use has decreased since the previous study due to manufacturing changes and a 13.5 per cent reduction in the weight of nappies.
The report highlights that the manufacture of disposable nappies has greater environmental impact in the UK than their waste management by landfill.
For reusable nappies, the baseline scenario based on average washer and drier use produced a global warming impact of approximately 570kg of carbon dioxide equivalents. However, the study showed that the impacts for reusable nappies are highly dependent on the way they are laundered
