* Due to a miscalculation, the Green Rankings significantly overstated ConAgra’s Water Use, thus giving it an incorrect Environmental Impact Score and Green Score. ConAgra should have been ranked 342 overall. ConAgra’s Environmental Impact Score and Green Score are not directly comparable to other company scores due to the miscalculation previously noted. We regret the error.
