This report has been prepared as part of the area for effort of “Differentiated payment” - an element of The Danish Voluntary Agreement on WEEE. The purposes of this report are the following: - Clarification of the extent to which differentiated payment models can drive the market for eco-design in a positive direction and give sufficient incentives to promote the willingness to invest. - Assessment of administrative costs associated with a differentiated payment system. To meet the defined purposes this report describes two activities answering the questions behind the above purposes: - A price sensitivity and willingness-to-pay analysis assessing what it takes to shift consumers from different types of EEE products and how much each consumer is willing to pay for eco-designed EEE products that are more readily recyclable when it comes to the different resources contained in the products. - A screening and summary of experience from abroad with differentiated models: France and Sweden, respectively.
