Notably, without accounting for persistence, the incentive to switch to these alternative plastics is weak, given their increased cost and limited reductions in GHG emissions (if at all) compared to current plastics (Figures ). However, adopting alternatives could be incentivized by the value gained by reducing the cost of plastic pollution. Savings to the cost of pollution per 1000 lids from switching to CDA or PHA compared to current plastics were estimated to range from $1.46 to $220.01 and -$0.40 to $220.49, respectively (Figure ). Given the billions of lids consumed annually, these savings could translate to societal benefits of hundreds of millions of dollars for this item.
