We did the cloth diaper thing for a while and I was happy to do my own little part for the environment, but as soon as I realized how poorly cloth diapers performed compared to disposables, we switched. Now it seems that using cloth nappies might not be as environmentally friendly (in regards to greenhouse gas emissions) as everybody assumed: Blow to image of ‘green’ reusable nappy
“A government report that found old-fashioned reusable nappies damage the environment more than disposables has been hushed up because ministers are embarrassed by its findings…
…The report found that while disposable nappies used over 2½ years would have a global warming , impact of 550kg of CO2 reusable nappies produced 570kg of CO2 on average. But if parents used tumble dryers and washed the reusable nappies at 90C, the impact could spiral to . 993kg of CO2 A Defra spokesman said the government was shelving plans for future research on nappies.”
I guess the thing to remember is that the carbon footprint is only a part of the total environmental impact.
