Journée mondiale de l'environnement (MER) is an annual event that is aimed at being the biggest and most widely celebrated global day for positive environmental action. Les activités de WED ont lieu toute l'année et point culminant sur 5 Juin de chaque année, impliquant tout le monde de partout.
La célébration du WED a commencé en 1972 and has grown to become one of the main vehicles through which the United Nations stimulates worldwide awareness of the environment and encourages political attention and action.
Through WED, the United Nations Environment Programme is able to personalize environmental issues and enable everyone to realize not only their responsibility, but also their power to become agents for change in support of sustainable and equitable development.
WED is also a day for people from all walks of life to come together to ensure a cleaner, greener and brighter outlook for themselves and future generations.
