Mandatory sequestration could make net CO2 emissions from bitumen extraction no worse than those from conventional oil wells, and perhaps even better. Another obvious condition is mandatory timetables for restoring strip mines and tailing ponds to their natural condition.
明摆的条件之一是强制“封存”二氧化碳（提取空气中的二氧化碳并将其深埋地下）。强制封存可以让提取沥青时的净二氧化碳排放与常规油井相当，甚至可以低于常规油井的排放水平。另一个明摆的条件是强制规定时间表要求露天矿和尾矿池复原到自然状态。
