[4] Alongside Liêm Hoang Ngoc, he later co-drafted a controversial 2014 report highlighting problems with the European Union-led bail-outs of Greece, Portugal, Cyprus and Ireland during the European debt crisis.

Ahead of the 2014 European elections, the ÖVP re-nominated Karas as its lead candidate.

[8][9] In 2021, Karas was appointed to the EPP group's task force for proposing changes to its rules of procedure to allow for “the possibility of the collective termination of membership of a group of Members rather than just individual membership”, alongside Esteban González Pons, Jan Olbrycht, Esther de Lange and Paulo Rangel.

[10] In late 2021, Karas announced his candidacy to succeed Sassoli as President of the European Parliament.

[1] Following the 2014 elections, Karas joined fellow MEPs Sven Giegold, Sylvie Goulard, Sophie in 't Veld and Alessia Mosca in an open letter aimed at exerting pressure on the President of the European Commission and national government leaders during the nominations process to improve the gender balance in the composition of the European Commission.

[14] In 2005, EU parliamentarian Hans Peter Martin revealed that Karas collected thousands of euros of "daily allowance" of 262 euros a day, even though he was often only in Brussels for a few hours on those days or it was a matter of holiday weeks.
