Launched in 2020 in partnership with Teragir to strengthen sustainable development initiatives in hotels, the Clef Verte/Green Key label is the first hotel ecolabel recognised worldwide (source: Teragir). Clef Verte-labelled hotels demonstrate effective environmental management and responsible practices based on 100 to 120 criteria covering 7 themes, including water management.
By 2022, the 32 hotels in Marseille with the Clef Verte label will have saved 3 million litres of water every month. And in 2023, thanks to the 10 new establishments enrolled in the Clef Verte programme, 4 million litres of water will be saved every month.
