Pollution from tire wear can be 1,000 times worse than a car’s exhaust emissions, Emissions Analytics has found. Vehicle tire wear pollution is completely unregulated, unlike exhaust emissions which have been rapidly reduced by car makers due to the pressure placed on them by European emissions standards.

finds that private jets are 10 times more carbon-intensive than airliners on average, and 50 times more polluting than trains in terms of CO 2 emitted per passenger-km. And yet, super-rich super polluters are flying around like there’s no climate crisis. The report, Private jets: can the super-rich supercharge zero emission aviation?
Researchers from Surrey’s Global Center for Clean Air Research (GCARE) in the UK have investigated the amount of harmful air pollutants babies potentially inhale while out in a stroller with their parents or caretakers. There was substantial variability in measured concentrations of different pollutants within each run (e.g.,
