Implement lasting educational reforms throughout the European Union

Nachhaltige - sustained, permanent, lasting

bildungspolitische - educational policy, educational politics, concerned with the government, state, political parties

Akzente - accents, main points of emphasis

auf europaeischer Ebene - in a European context

Sounds interesting!

Hard to translate with limited context!

Not radically different from the rest but another possibility to choose from..

Another variation.
"Akzente" is not equal to trends or reforms.
I like the literal translation best in this instance, of course without having seen the surrounding context.

Just another shot at it ... I think it's all in there!

of sustainable education policy on the European level

Apologies for adding yet another answer (expecially Sonja!), but I still feel it's twice as likely to refer to sustainable policy than long-term policy.
