Opportunities of considering time in LCA studies are shown through our "dynamic" system and impact modeling of different domestic hot water systems. Our "dynamic" carbon footprint modeling changed the conclusion of the equivalent "non-dynamic" evaluation which shows that temporal consideration might provide a more representative assessment. The temporally characterized distributions of elementary flows we used also bring new analysis opportunities for practitioners. As an example, we believe that such information will enable the simple identification of products with high potential for future environmental improvement. Describing the temporal distributions of natural resource extraction could be another opportunity for dynamic modeling as they would provide valuable information on when and how consumption could be an issue.
