How might one define 'super' profits, that should be subject to windfall tax? When (fossil fuel) firms see abrupt rises in profits (see latest from BP), we know that: new innovations have not come on line; new investments are not (now) 'paying off'; but rather; firms' costs remains broadly similar to what they were, but the price they can charge for their product has risen due to external market issues! In other words *they* have done nothing to earn such profits #FossilFuels #politics
