Public perceptions of the value of reducing marine plastics in Australian waters
研究调查了澳大利亚公众对减少海洋塑料的支付意愿，发现人们更偏好重新设计和回收策略，而非简单的回收或再利用，为政策制定者提供了参考。
Plastic is the most pervasive type of marine litter and is found in all of the world's oceans and seas, even in remote areas far from human activities. In Australia, evidence has demonstrated that plastic pollution in the oceans is a serious threat to marine life and the marine environment more generally. In response to the adverse effects of marine plastic pollution, the Australian Commonwealth and state government's focus on plastics has shifted from a linear ‘take-make-dispose-of’ economy to a more circular economy approach. This study identifies different policy strategies that align with the 4R framework (Reduce, Recycle or Reuse and Recover) of a circular economy for plastics and provides estimates of the public's Willingness to Pay (WTP) for the reduction of plastics in marine waters. The results, from our Australian case study, indicate a preference for Redesigning and Recovering approaches over Recycling or Reuse policies. Results indicate a WTP of $7.52 to $23.50 for attributes based upon redesign and a $0.84 to $0.87 range for attributes based upon recovery at the household level. The findings of this study are useful for policy makers focused on the reduction of marine plastic pollution and strengthening a circular economy for plastics.
