In Spain, over 81 percent of buildings have the worst energy rating, while in France, nearly a third of homes were built before 1949, and in Austria, over 850,000 homes are of similar age. Although Lithuania is actively modernizing housing, last year, 35,000 homes were awaiting renovation. In Lithuania, Birštonas, Palanga, and Druskininkai are leading municipalities in housing modernization, with APVA reporting an increase in renovated buildings and a focus on achieving B energy efficiency class. Despite recent improvements, only about 12 percent of all multi-family houses in Lithuania have been renovated over the last two decades. Romania has one of the oldest housing stocks in the EU, with concerns raised about both energy efficiency and safety due to its seismic activity. EU member states are addressing the issue of aging housing, particularly regarding energy efficiency, as old buildings contribute significantly to CO2 emissions. Lithuania currently has an ongoing multi-family house modernization project, supported by a €165 million allocation from the European Investment Bank.

PULSE is an initiative for cross-border collaborative journalism in Europe co-funded by the European Commission under Grant Agreement n. PO 4500158093.

PULSE is an initiative coordinated by OBCT that has been promoting intensive journalistic cross-border collaborations in Europe since 2024. Its main aim is to help strengthen the European public sphere by reporting on and telling stories from new and diverse perspectives.

At the heart of PULSE are 10 leading national news outlets (Delfi – Lithuania, Deník Referendum – Czechia, Der Standard – Austria, EfSyn – Greece, El Confidencial – Spain, Gazeta Wyborcza – Poland, HotNews – Romania, HVG – Hungary, Il Sole 24 Ore – Italy, Mediapool – Bulgaria) and three transnational organisations, including OBCT , n-ost and Voxeurop .

Additional outlets and journalists are involved as associate partners, including EUobserver , Føljeton (Denmark), H-Alter (Croatia), Levila (Estonia), Rubryka (Ukraine), and The Journal Investigates (Ireland).

PULSE is driven by a sort of virtual transnational newsroom made up of journalists from all the publications involved. It collaboratively produces new journalistic content on European issues on a daily basis, coming in many different languages. The editorial output amounts to over a thousand publications per year, mostly in article form.

PULSE also runs 4 thematic networks open to any European journalist interested in crucial issues such as EU enlargement, relations between the EU and other global powers, the EU’s green transition, or media and the information society. These networks function as online communities and periodically publish calls for pitches.
