It won't really come as a surprise to the reusable world that reusables use 25% less C02 than single use disposable nappies, but the research and findings are hopefully the evidence the government need to now move forward with implementing some changes to our mainstream baby nappy consumption.
The report goes on to state it has taken into account many variables, including the washing and drying aspect of reusables, which for many is a concern for its environmental weighting. Even with this consideration the environmental impact of a reusable is better than that of a disposable.
