BUSINESS BRIEFING / ENVIRONMENT

PG&E; Corp., the owner of California’s largest utility, is leaving the U.S. Chamber of Commerce because of the business group’s opposition to federal climate change legislation.

The San Francisco company won’t renew its membership because of “fundamental differences” with the chamber’s approach toward efforts to curb global warming, Peter Darbee, PG&E;’s chief executive, said in a letter to chamber President Tom Donohue.
