Paris plans to increase parking fees for SUVs, including electric and hybrid ones, as part of its effort to combat "auto-besity" and reduce the number of big, polluting cars on the streets. City officials state that the number of SUVs in Paris has risen by 60% over the past four years, and they account for 15% of the private vehicles parked there every night. Paris Mayor Anne Hidalgo has organized a referendum for residents to vote on the parking fee increase on February 4, with the intention of mainly affecting suburbanites and out-of-towners.
