In May 2012, ConocoPhillips, previously ranked among the Greenhouse 100, separated its downstream business to create a new, publicly traded company known as Phillips 66. In connection with this separation, downstream assets (such as refineries and terminals) and liabilities were transferred to Phillips 66. The assets listed are no longer owned or operated by ConocoPhillips.
