The choice of greenhouse gas emissions accounting method is important because it affects the way climate burdens are allocated between states. This paper investigates the significance of state jurisdiction for this choice. It assesses three arguments from jurisdiction against consumption-based emissions accounting: the fairness argument from retrospective responsibility; the fairness argument from prospective responsibility; and the effectiveness argument. It argues that former two arguments fail since attributing emissions to importing states neither unfairly blames these states nor asks too much of (...) them. However, the effectiveness argument provides a strong potential reason against consumption-based emissions accounting. To the extent jurisdictional control is needed to reduce some emissions, and production-based accounting incentivizes states to reduce these emissions, there is a reason of environmental effectiveness for sticking with production-based accounting.
