Clinton, Wal-Mart Push 'Green' Cities

SEATTLE (AP) — Former President Bill Clinton told more than 100 mayors Thursday that stopping global warming depends on them demonstrating that it makes economic sense. He said his foundation is teaming up with Wal-Mart Stores Inc. to save cities money on environmentally friendly supplies by buying in bulk.

"We will not get a global agreement on climate change unless you can prove this is not a burden,'' he said. "This is the greatest opportunity we have had in our lifetimes.''
