Transportation shapes how people access jobs, healthcare, education, and each other. This archive tracks real progress in transit, infrastructure, electric vehicles, cycling, and more — from local wins to national policy shifts worth knowing about.
There are now more than 600,000 EVs in Norway. In 2017, the country pledged to end the sale of petrol and diesel cars by 2025. The government also has exempted new EVs from purchase tax and sales tax.
The European Commission has approved the move which will abolish flights between cities that are linked by a train journey of less than 2.5 hours.
Solar-powered cars have moved from moonshot idea to manufacturing reality — and that shift matters more than any single vehicle rolling off the line. Lightyear’s debut model uses curved solar arrays across its roof and hood, harvesting enough sunlight to cover up to 40 miles daily — matching most people’s actual driving habits. At $255,000, it targets early adopters, though with solar panel costs having dropped over 99% since the 1970s, wider accessibility may follow. A car that generates its own fuel from sunlight quietly answers one of the strongest critiques of electric vehicles.
Hydrogen-powered flight moved from theory to reality when Rolls-Royce and easyJet successfully ran a modern jet engine on green hydrogen produced entirely from wind and tidal energy. Unlike battery-electric approaches, hydrogen burns clean — releasing water vapor instead of carbon dioxide — and this test proved a real engine can handle it. Aviation has been one of the hardest sectors to decarbonize, so a confirmed proof of concept opens a genuine path forward. Every major breakthrough in flight history started exactly here: on the ground, with an engine, and a question that finally got answered.
Compared to traditional petroleum-based aviation kerosene, bio jet fuel can reduce carbon emissions by up to 50% throughout the entire lifecycle.
Hydrogen-powered passenger trains now cover an entire regional rail network in Lower Saxony, Germany — 14 Alstom Coradia iLint trains that have fully retired the diesel locomotives once used on the Cuxhaven-to-Buxtehude lines. Each train pulls oxygen from the air, combines it with hydrogen stored on the roof, and emits only water vapor, traveling roughly 1,000 kilometers between refuels. The regional operator has pledged to never buy another diesel train, citing both climate goals and the cleaner air passengers breathe at small-town platforms. It’s a modest fleet in a single corner of Germany, but it’s the first proof anywhere that diesel regional rail can be fully replaced — a template other countries with long, lightly used routes can now follow.
The amount of CO2 emitted during kerosene combustion in a jet engine equals that consumed during its production in the solar plant.
Australia’s Capital Territory is sending a clear signal to the rest of the country: the fossil-fuel car has an end date. The region surrounding Canberra wants at least 80% of new light vehicles sold there to be zero-emission by 2030, as a stepping stone to the full 2035 ban. Interest-free loans up to $15,000 and registration fee exemptions are already helping residents make the switch today. When a high-visibility jurisdiction at the heart of national politics demonstrates this transition is manageable, neighboring states face far less risk in following — and that ripple effect is exactly how national change begins.
The first site was launched on the 30th of June in Harare.
Sustainable aviation fuel just powered both engines of an Airbus H225 helicopter at the same time — a first for any rotorcraft, anywhere. Earlier tests had only run SAF in one engine at a time, so flying twin engines on 100% SAF marks a real leap toward proving the fuel works under the demanding, variable loads helicopters face. Airbus says SAF at full concentration can cut CO₂ emissions by up to 90% compared to conventional jet fuel, and the company is aiming to certify 100% SAF across its commercial aircraft and helicopters by 2030. For missions like search and rescue or medical evacuation, where batteries can’t yet deliver, this is one of the most promising paths to cleaner skies.
