Well, Conoco wasn't shipping Alaskan LNG to Japan because CONOCO didn't own any interest in Alaska until the so-called Conoco-Phillips merger.
Look the LNG line was approved in 1999, way before anyone proposed the Canadian route. My guess is that it wasn't CONOCO that originally proposed the Valdez route. CONOCO was just in place to convert some of the new builds into LNG carriers.
I agree that ConocoPhillips has not been the responsible part for the entire 35 years, but they continue to ship it today.
