The surprising simplicity of starting your first LCA

After writing about how LCA shifted my product mindset, I kept hearing the same reaction from other PMs: "It sounds powerful, but isn't it incredibly complex?"

I had the same worry. The acronyms alone, GWP, EPD, ISO 14040, feel like arriving in a new country without a translator. What surprised me is that starting an LCA is more like learning to cook than earning a chemistry degree.

A health check-up for a product

The breakthrough was to stop thinking of LCA as environmental accounting and to see it as a diagnostic. Instead of blood pressure and cholesterol, you check:

• Material extraction
• Manufacturing emissions
• Transport
• Energy during use
• End of life

Like a check-up, it finds problems you did not feel.

Hidden hotspots

A story I have heard many times in the LCA community: a team spends months optimizing product materials, then finds in their first LCA that packaging is a large share of the footprint. Packaging is a big part of global plastic waste, and it is easy to overlook when the product gets all the attention. That is the value of an LCA: perspective, not perfection.

You do not need complete data to start

Think of it like user research. Five good interviews can reveal the pattern. With LCA you can:

• Start with a screening-level assessment.
• Focus on the biggest impact categories first.
• Use industry-average data from databases like ecoinvent where specific data is missing.
• Iterate as better data arrives.

Free tools like openLCA make this possible without a budget.

The real value comes after

The assessment is the beginning. The value is in the decisions it changes: a material swap, a packaging redesign, a supplier conversation, a product claim you can now defend. That is where product managers come in.
