By Gerard Wynn
LONDON, Feb 13 (Reuters) - Known oil, gas and coal reserves may already contain a quarter more carbon than mankind can emit and still avoid dangerous climate change, putting the value of new oil exploration in doubt, said a former oil major executive.
The oil industry may be wasting $50 billion annually searching for new fields, said Jan-Peter Onstwedder, formerly BP's most senior risk manager. He left BP in December.
