Environmental impacts are most of the time calculated following the attributional approach, which basically means \"attributing a share of the cake\" of the environmental impacts to an actor or a functional unit. The Consequential approach is less known, but sometimes far more instructive regarding the short-term and long-term impact dynamics. This article presents both approaches and explains the benefits and biases of both.
