France's local elections on Sunday saw a green wave wash over the nation as the Greens party chalked up wins in the major cities of Marseille, Lyon, Strasbourg and Bordeaux. In Paris, incumbent Anne Hidalgo was returned as mayor promising more measures to reduce the city’s carbon footprint --and its pollution levels -- which fell dramatically under the covid lockdown.  Among the night’s biggest losers? Macron’s La Republic en Marche party which, despite its strong stance on environmental issues, suffered bruising losses at the ballot box.
