Occidental Petroleum Corp. shareholders voted in favor of a climate change disclosure proposal led by... California Public Employees' Retirement System ($318.9 billion) and Connecticut Retirement Plans & Trust Funds ($31.5 billion) requiring the company provide an assessment of its portfolio under the 2-degrees scenario, the concept of limiting the average global temperature increase to 2 degrees Celsius...The proposal received more than 50% of the votes...[including] the backing of Occidental's largest shareholder, BlackRock, which owns a 7.8% stake. [BlackRock] said it took action due to the "lack of response" on the issue by the company and a lack of improvement in its climate-change related reporting following a similar proposal last year which received more than 40% support. This year's vote marks the first time BlackRock has supported a climate-change related shareholder proposal.
