Italy's wind energy association, Associazione Nazionale Energia del Vento (ANEV), and the Italian arm of the World Wildlife Fund (WWF) have agreed to work together to minimise the impact of wind farms on the environment and biodiversity. The accord establishes criteria for identifying suitable sites and excludes construction in areas that are important for the migration of birds, protected species or for other particular environmental qualities. The agreement also commits wind energy producers to restoring sites at the end of a wind farm's life. WWF says wind power is essential for meeting Italy's Kyoto commitments. The environmental association's responsibilities under the agreement include monitoring the possible interference of wind farms with the natural habitat and biodiversity.
