Melissa Winters from the EPA came to UW Tuesday to talk to my Environmental Innovation Practicum class about Life Cycle Assessment, also known as Life Cycle Analysis (LCA). She talked about an assessment Proctor and Gamble did its Tide brand in which they discovered the greatest environmental impact happened when the product was used in the home. Hot water washing. So they reformulated Tide to create a cold water only detergent.
Melissa also mentioned an ebook analysis I’ve written about before. I’d discovered the analysis through Conservation Magazine, a favorite of mine, but it originated in a New York Times op-ed piece written by the folks who did the analysis, Daniel Goleman and Gregory Norris, both well known names and leaders in LCA work. Norris founded the International Journal of Life Cycle Assessment, which is a tremendous resource (check out this LCA on algae biodiesel as an example).
When I wrote about the e-reader analysis in July, I noted that you needed to read 40-50 books a year to make an e-reader the better choice over paper books, based on the report in Conservation Magazine. Melissa commented that if we took greenhouse gas emissions into account, it was actually 100 books. If we looked at human impact, it was somewhere in between those two numbers. My iPad is a lot more than an e-reader to me, but I still glanced at it guiltily.
Since Melissa works with the building industry, the whole conversation reminded me of a TEDTalk I really enjoyed a while back, so I want hunting. It’s Catherine Mohr on building green and I think it’s great! It playfully but powerfully demonstrates that obvious answers for what’s the “greenest” choice is often very wrong. Or as she puts it: “Sometimes the things you least expect … have a bigger impact than any of those things you’re trying to optimize.”
The next morning, I spotted a story from dexigner.com on how the Cascadia Green Building Council had commissioned an LCA study on the “Environmental Impacts of Wastewater Treatment Strategies” and had just released the report. It’s a good read for anyone connected to the building industry or anyone who just wants to get a handle on what a life cycle analysis can uncover.
From a marketing perspective, a life cycle analysis does two things: 1) it’s an insurance policy that you know the up and downsides of your product before a competitor figures them out and uses the latter against you, and 2) assuming you do well in the analysis, it’s a grabbag of positive messages you can take to the market. From a business plan perspective, it’s an insurance policy to demonstrate you know the risk associated with your business and a grabbag of positive messages to take to investors, employees and business partners.
The trick for cleantech and other green entrepreneurs is the cost. Conducting LCA is pricey. For startups, a true LCA may be out of reach. But you can still do a significant amount of digging for data, look for comparables in your industry or adjacent ones, and make informed decisions. You can get a primer on life cycle assessment on the EPA’s website and well as a list of resources to serve as a starting point for research life cycle assessment on any product or service category.
Get as smart as you can about the potential environmental impact of your products or services. It’s smart business.
