Italians have the most cars among EU countries. Not surprised, I was honestly pretty shocked by the traffic and air quality in Rome 😔.

First five countries: Italy 709, Finland 671, Cyprus 670, Luxembourg 668, Poland 639
Germany on eleventh place 593

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...

Tellus has a long, storied history. I submitted my first paper there 30 years ago for that reason. I'm excited about Tellus's rebirth and plan to submit my next paper on the Arctic Ocean carbon cycle there. In the age of money-grubbing publishers, I encourage you to consider Tellus.
Publication Fees
Starting in 2026, Tellus operates as a Diamond Open Access journal.
All articles are published Open Access with no fees for authors — no submission charges and no article processing charges (APCs).
This model is made possible through financial support from the Max Planck Digital Library (MPDL), the International Meteorological Institute (IMI), and the Bolin Centre for Climate Research, which together cover the journal's publication costs.

30% of the world’s CO₂ emissions have a carbon price. What we pay for something in a shop often doesn’t reflect its true cost. Producing goods causes damage through carbon emissions that drive climate change, but the receipts for that damage rarely show up in the price.
