And don't miss Chris Hughes on Shell's efforts at atonement: "If the oil price sinks, it's capital investment that gets cut back. Heads, shareholders win; tails, investment loses. Shell's investor-friendly moves are partly about atoning for the past and undoing the dilution inflicted by share issuance for the dividend and the purchase of BG Group in 2016. Meanwhile, Shell claims an industry first in its carbon commitments. If only it could rush to shift to renewables as quickly as it's dashing to please its owners."
