L'Ufficio federale dell'ambiente ha tracciato un suo bilancio intermedio della Conferenza sui mutamenti climatici in corso a Parigi sottolineando che finora i negoziati non hanno fatto registrare progressi significativi.
La delegazione svizzera -informa ancora l'ente- s'è data molto da fare per strappare qualche risultato concreto ed è delusa che i suoi sforzi non siano stati coronati da successi.
Il vertice organizzato dalle Nazioni Unite s'è aperto questa settimana e si concluderà l'11 dicembre. L'obbiettivo è di raggiungere un accordo vincolante volto a limitare ad un massimo di 2 gradi l'aumento della temperatura terrestre rispetto all'era preindustriale. Vi partecipano 10'000 inviati in rappresentanza di 195 nazioni. A livello di scambi informali, quasi tutti hanno manifestato la volontà di raggiungere un'intesa, dopo due decenni di infruttuoso dialogo.
