PGE – Climate Change – 2011 (status: Withdrawn; Company will address)
In October 2006, a report authored by former chief economist of the World Bank,
Sir Nicolas Stern, estimated that climate change will cost between 5% and 20% of global
domestic product if greenhouse gas (GHG) emissions are not reduced, and that GHG's can be
reduced at a cost of approximately 1% of global GDP per year.
