Overview

What is Lifecycle Assessment?

Lifecycle Assessment, or LCA, is an analysis to understand the total cradle-to-grave impacts of a good or service. The impacts most commonly measured are costs, energy, and emissions. The lifecycle assessment of costs has been measured for hundreds of years. Accounting for all the costs of a good or service is necessary to determine if a product or service will be profitable and competitive. However, accounting for all the costs can be complex depending on your final product or service.

Why Does it Matter?

LCA is important because you may have a good or service that reduces costs, energy, or emissions in one area of its use, but overall the impacts are larger. For example, someone develops an amazing process to reduce the manufacturing costs, energy, and emissions of a toaster, but then during the use of the toaster it uses more electricity than it used to. Depending on how much more electricity is used it could offset the costs, energy, or emissions savings in the manufacturing of the toaster, undermining the objective to reduce the overall costs, energy, and emissions of making a piece of toast.

Put another way, lifecycle assessment lets us better understand the true impacts of any given good or service. It’s important information for scientists, consumers, and policymakers alike.
