To prioritize data collection, companies should start by identifying processes within the product’s life cycle that contribute the most to greenhouse gas emissions. This can be done through a screening process to rank processes by their emissions. Focus should be placed on processes that either consume large amounts of GHG-intensive materials or are known for their high emissions. It is also helpful to consider uncertainties in the data and prioritize areas where there is high uncertainty or a large impact on the overall results. This way, companies can efficiently allocate resources to collect the most critical data first.
