<s>[INST] The next text is a question of a member of the European parliament:"Finland and Sweden were not represented in the European Parliament when it discussed the application of weights and dimensions of heavy goods vehicles in Member States. Probably for this reason, the special conditions of the sparsely populated Nordic countries were not sufficiently apparent. Finland and Sweden have applied their own standards for so long that the infrastructure and equipment have been entirely renewed.  If in the countries concerned transport equipment had to be renewed because of EU Directives, transport costs, which are already exceptionally high, would rise, with a detrimental impact on economic growth and unemployment. The fragile environment would be strained even further by higher emission levels.  In view of the above, does the Transport Commissioner, in accordance with the principle of subsidiarity, intend to introduce measures which would allow existing standards on weights and dimensions to be applied in sparsely populated countries?"

Finland and Sweden were not represented in the European Parliament when it discussed the application of weights and dimensions of heavy goods vehicles in Member States. Probably for this reason, the special conditions of the sparsely populated Nordic countries were not sufficiently apparent. Finland and Sweden have applied their own standards for so long that the infrastructure and equipment have been entirely renewed.  If in the countries concerned transport equipment had to be renewed because of EU Directives, transport costs, which are already exceptionally high, would rise, with a detrimental impact on economic growth and unemployment. The fragile environment would be strained even further by higher emission levels.  In view of the above, does the Transport Commissioner, in accordance with the principle of subsidiarity, intend to introduce measures which would allow existing standards on weights and dimensions to be applied in sparsely populated countries?
