Dozens of environmentally-friendly mayors from around the world are set to sign a Vatican declaration urging their national leaders to approve a “bold climate agreement” to tackle global warming.
A total of 60 mayors are attending a two-day climate conference at the Vatican featuring an audience with Pope Francis, whose recent environment encyclical is aimed at keeping up the pressure on world leaders ahead of Paris climate negotiations in December.
The final declaration states that “human-induced climate change is a scientific reality and its effective control is a moral imperative for humanity”.
