On Wednesday, investors filed shareholder resolutions with Chesapeake Energy, Exxon-Mobil, Chevron, ConocoPhillips and 14 other American oil-and-gas companies.
The investors want the companies to disclose their plans for managing environmental and workplace challenges including hydraulic fracturing or fracking, greenhouse gas emissions and worker safety.
"The common thread of these resolutions is stronger management focus on environmental and social challenges that will have real bottom line impacts," said Mindy Lubber, director of the Investor Network on Climate Risk and president of Boston-based Ceres, that coo0rdinated the filings.
Most of the resolutions are associated with the financial risks from fracking and seek detailed financial accountings of how companies are addressing the risks associated with community concerns.
"As community opposition and regulatory risks for fracking operations grow, investors are likewise concerned about how businesses are managing their exposure to these risks," said Larisa Ruoff of Green Century Capital Management.
