PARIS — Konbini reports that the Paris region’s transport union voted on a project to end free public transportation on days of high pollution and instead offer a one-off day pass that would cost about $4 on days when there’s a surge in pollution levels, rather than the normal cost of $18.39.

While making all public transport free for the day does help in reducing pollution from gas emissions, the union estimates that the loss of profit adds up to approximately $4.2 million per day for the region, which would be reduced to approximately $532,000 if the new plan were to be put in place.

The number of free transport days, as well as diverted traffic days, should increase this year thanks to the relaxing of the conditions necessary to trigger them. For the full story, click here.
