One limitation of Life Cycle Assessment is that it relies on the expectation of what will happen to a product as predicted at the point of creation. However, changes in technology, the economy, and end-of-life treatment practices may alter future emissions. This paper describes a study done to develop a model to improve the accuracy of estimated emissions by incorporating uncertainty into the expected impacts of a product by considering events that alter the phases that have not occurred. A case study using this model on a laptop shows use phase GHG emissions reduced by up to 55% in one scenario.
