Italians have the most cars among EU countries. Not surprised, I was honestly pretty shocked by the traffic and air quality in Rome 😔.
Number of passenger cars per thousand inhabitants in 2025 from Eurostat.
First five countries: Italy 709, Finland 671, Cyprus 670, Luxembourg 668, Poland 639
Germany on eleventh place 593
EU mean value 584

There’s still so much potential for #ClimateAction in traffic. 60% of European CO2 emissions in traffic are from cars. Last year, 17% of new cars in the EU were electric vehicles. German text on car traffic in the EU: www.destatis.de/Europa/DE/Th...
Carbon dioxide emissions from road traffic in the EU in 2024: 60% from passenger cars and motorcycles, 27% from heavy-duty trucks and buses, 12% from light commercial vehicles; a total of 758 million metric tons. Source: https://www.destatis.de/Europa/DE/Thema/Verkehr/Auto.html

Preliminary Mecklenburg-Western Pomerania election results: the chancellor’s party CDU (Christian Democratic Union) now below 5%, which means they will not have a seat in the state parliament anymore.

My new favorite pastime is checking websites for AI generated images. Just kidding but I love the new EU rules, so informative. I hope people will take them seriously and comply with them. AI generated images need to be marked in a professional context, but not in a private context.

More than 5,000 people are estimated to have died in Germany during the recent heatwave. Just look at the peak on the right, the dashed black line are reported deaths. The red line is a model estimate, and the blue line is a model estimate without heat. www.rki.de/SharedDocs/B...
Abbildung 2. Verlauf der Sterbefallzahlen (schwarz) im Zeitraum 2025 bis KW 26/2026 wie vom Statistischen Bundesamt berichtet. Die Zahlen der letzten neun KW können noch durch Nachmeldungen beeinflusst werden und sind gestrichelt dargestellt. Außerhalb des Sommerhalbjahres (KW 15 bis 40) sind die Sterbefallzahlen ausgegraut. Die rote Linie zeigt den modellierten Verlauf der Anzahl von Sterbefällen mit Hitze, die blaue Linie den modellierten Verlauf ohne Hitze. Der Effekt der Hitze zeigt sich vor allem in Wochen, in denen die bundesweite Wochenmitteltemperatur 20°C überschreitet (WMT, gelbe Fläche). Wird die 20 °C Schwelle nur in einzelnen Bundesländern überschritten, können leichte Abweichungen zwischen der modellierten Anzahl von Sterbefällen mit und ohne Hitze (rote und blaue Linie) auch außerhalb gekennzeichneter Hitzewochen auftreten.
