Life Cycle Assessment Software Tools – Overview

Toby Liebsch
Life Cycle Assessments are complex calculations, and tools make it much easier. But which LCA tool is the right one for your job?
Life Cycle Assessment Tools

Historically, a Life Cycle Assessment (LCA) was primarily used for research purposes. It’s no surprise that most LCA software share this background. The first LCA tools were developed within universities. Even today, many tools that help calculate Life Cycle Assessments have strong ties to the academic field.

From academic to business solution

Life Cycle Assessment tools have been around since 1990. With sustainability, climate change and the circular economy being more publicly debated topics, the market for LCA tools itself has also developed.
Today, there are many different LCA tools available. And they all serve different purposes. Some still share the academic background of LCA, yet others have been developed to help businesses measure their environmental footprint. Some are focused on specific industries, while others can be used in many different industries.
In this article, we will give you an overview of the most popular LCA tools (our own solutions, Ecochain Helix and Ecochain Mobius, as well as the four other most established LCA solutions SimaPro, GaBi, oneClickLCA and openLCA). We will compare their functionalities as well as compare them side by side in a table.

Who is this overview useful for?

This guide is supposed to provide a quick overview into the world of LCA software and when to use which tool. However, each sustainability challenge is different. We are happy to help if you have any questions – reach out!
As you can also read in our LCA Beginner’s Guide, the goals of an LCA can be very different. For this overview, we’re focusing on the solutions that are most used commercially.

LCI Databases: Backbone of LCA calculations

Life Cycle Assessment calculations rely on Life Cycle Inventory data. Whilst many tools offer their own databases, most databases are commercially available for a fee. That means that that data has to be taken into consideration when calculating the price of an LCA tool.

openLCA is the cheapest solution in our list – because it’s free. openLCA is an open-source LCA solution, which means that it is attractive for anyone starting off in the LCA world without a big budget. However, openLCA also has extensive deep-dive functionality, which also makes it useful for users with a more technical background. openLCA Website

SimaPro has been established for more than 30 years and is probably the most well-known LCA Tool in the market. SimaPro is used primarily in the academic field and by experienced LCA consultants. SimaPro is a complex application with many optional add-ons that make it very versatile, and it enables its users to dive deep into the LCA calculations of a product. SimaPro Website


Like SimaPro, GaBi has been established since the mid 90’s. It is also a very established LCA tool, being used in many industries, especially in its home market, Germany. Just like SimaPro, GaBi is a rather technical solution with many potential add-ons for product development. GaBi is used especially by consultants, but also in-house. GaBi Website


OneClickLCA is the only application in our list that is specifically designed for one industry – the construction sector. Because OneClickLCA focuses on one specific industry, it offers many functionalities specifically needed for the construction sector.
