To make an LCA you first need data on your product(s). But what kind of data, often comes up in the conversation. In this podcast episode, we will go through the two main types of data - primary and secondary data. And what's the difference between them in LCA?

What kind of data do you actually need to make a Life Cycle Assessment (LCA) of your products? Think of the energy usage for your manufacturing and waste processes, data on your purchased & used raw materials, etc. Much data can be found in your own finance or purchase department. But with supply chain data (e.g. purchased raw materials) it’s trickier. How do you get to know the exact impact behind the specific materials you purchase? It’s information your suppliers hold.

This raw supply chain data is called primary data. And it’s crucial for credible footprint calculations. The other option is secondary data. Meaning already existing scientific databases collected by previous researchers.

To get a comprehensive look into the differences and uses of each type of data, we spoke to Ecocahain’s Zazala Quist - who recently did a deep dive into all things data.
