"Warren Buffet-owned Berkshire Hathaway on list of top 25 companies with least efficient and oldest ‘sub-critical’ coal power plants "

"The 100 global power companies most at risk from growing pressure to shut highly polluting coal plants have been revealed in a new report from Oxford University.

Chinese companies dominate the top of the ranking but US companies, including Warren Buffett’s Berkshire Hathaway, occupy 10 of the top 25 places.

The analysis, produced to help investors assess the risk of major financial losses, also found French energy giant GDF Suez was third in the list of most polluting coal station fleets in the world."
