=== SES-I (2004–2009) ===
The first SES legislation (SES-I) has been viewed as 'a real breakthrough', as is stimulated progress in harmonisation in [[air navigation service provider]]s (ANSPs), the establishment of national supervisory authorities and EU competences over certification of these services.<ref name="Crespo"/> However, progress was slow in the next two years; the establishment of [[functional airspace block]]s (FABs) was disorganised, little progress was made in improving cost efficiency, growing air traffic threatened capacity, and with tackling climate change emerging as a political priority, European aviation's emissions had to be mitigated.<ref name="Crespo"/> In response to strong demands from the industry, EU member states and other stakeholders, the [[Barroso Commission]] appointed a new high level group to develop a more detailed regulatory framework in November 2006.<ref name="Crespo"/> The group published its report in July 2007; it contained 10 recommendations, including making the EU the primary regulator of European aviation in order to set performance targets, safety requirements, introduce economic regulation of ATM services, incentives for ANSPs to achieve their objectives, and streamlining the implementation of FABs. Eurocontrol would provide the EU with technical support for regulations, safety regulation would be delegated to the [[European Aviation Safety Agency]] (EASA), and member states would be urged to hurry up with their commitments to implement the defragmentation of airspaces.<ref name="Crespo"/>
