The very simple explanation for this is that incineration of polyester in Denmark has a better environmental profile than incineration in Finland, and the Danish benefits from increased reuse or recycling are correspondingly lower. The real benefits should be examined by looking at the difference between scenarios on the national level. The Nordic average, however, gives a good indication of the benefits in general, taking into consideration that the marginal energy scenarios for individual countries is determined with some uncertainty (see 4.1.2).
