“…In the last third of the test phases, 397 companies joined the tests. Tests have shown that the introduction of longer vehicles in the Netherlands has contributed to a reduction in the number of kilometres travelled and an increase in cargo transport, as well as, very importantly, a reduction in CO2 emissions from 63 to 56g per ton-kilometre, which represented about an 11% reduction in CO2, and in NOx emissions from 0.4 to 0.37g per ton, which involved a 14% reduction [27][28][29][30][31]33,34]. In addition, analyses have shown that there has been an increase in transport efficiency, and the Dutch are also trying to test longer 32 m vehicle sets which, if the tests are successful, they will authorise for use on fixed routes.…”
