In a recent Council document (6193/09) the progress in this field is listed in detail:
Nine fields in which administrative burdens are supposed to be reduced as well as 50 regulatory areas and the respective regulations/directives that are subject to simplification are mentioned in the Annex I+II of the document. For each measure/area you can see the state of play. Some have been finalised already in 2008 while others will only be dealt with starting from this year.
From the main text of the document I like the following paragraph:
[T]he Presidency stresses the importance of short executive summaries, for presentation of quantified key benefits and costs, including administrative costs for businesses, and considers that such summaries should normally cover all options, not just the chosen one. Thoroughly evaluated alternatives can speed up the decision-making process in the institutions in cases where the co-legislators would opt for different solutions than the originally proposed option.All more or less important documents of the European institutions should have short and understandable executive summaries. This would ease citizens' access to the EU information space and would not force us to read through endless and quite boring documents.
But I suppose this will never happen, so I'll just continue dreaming...
