2007年，國務(wù)院辦公廳發(fā)出《關(guān)于限制生產(chǎn)銷售使用塑料購物袋的通知》，試圖通過行政手段，采用經(jīng)濟方式“限制和減少塑料袋的使用，遏制‘白色污染’”。這份被群眾稱為“限塑令”的通知拿商超塑料購物袋“開刀”，實行塑料購物袋有償使用制度。從2008年實施至今已經(jīng)整整十年，效果如何?環(huán)境是否有所好轉(zhuǎn)?
很多研究可降解材料的專家表示目前禁塑限塑的效果并沒有達(dá)到預(yù)期的效果。伴隨著人們生活水平的提高，生活質(zhì)量和要求越來越高，帶來了大量的過度包裝。這也是需求的劇增而導(dǎo)致了塑料用量越來越大。比如快遞外賣等等行業(yè)所產(chǎn)生大量塑料垃圾的問題，并不是一個限塑令就可以解決的。
