However , an in-depth study from the environment agency ( pdf ) found that the total impact on global warming could be slightly higher for washables than for disposables .

不过，一份环保机构的深入研究发现（pdf），可洗尿布对于全球暖化的影响甚至还略高于一次性尿布。

Washables can have a lower carbon footprint , but only if you have an energy-efficient washing machine , use a 60-degree wash cycle , limit yourself to 24 nappies , and don 't tumble dry or iron them .

只有在你有一个高能效的洗衣机，使用60度洗衣周期，限制在24片尿布以内，不要甩水和熨干的情况下，可洗尿布的碳足迹才会相对比较低。
