From June 2018 people aged over-65 with an income less than €2,200 per month will be able to get their free Navigo pass, which allows travel on the Metro, RER trains, trams and buses in the greater Paris region.
The measure, announced by Paris Mayor Anne Hidalgo on Wednesday morning on France Bleu will benefit around 200,000 elderly people.
At the moment, retirees in the French capital have access to lower tariffs thanks to the Navigo Améthyste Seniors card.
But in order to get hold of one, applicants must meet a series of criteria including living in Paris for at least three years, and the amount of help varies according to their financial situation.
Hidalgo believes the new measure will see the elderly favour public transport over their cars.
For other Parisians, the price of the Navigo pass changes nearly every year. In 15 years, the price has gone up by €29.15, with an average yearly price hike of €2.
In 2017, The Local reported on the latest price hike which saw tariffs increase from €73 to €75.20 each month.
