Life-Cycle Assessment and How to Apply it to Your Buying Habits

Life-Cycle Assessment, or LCA, as defined by the the EPA is "a technique to assess the environmental aspects and potential impacts associated with a product, process, or service, by: compiling an inventory of relevant energy and material inputs and environmental releases; evaluating the potential environmental impacts associated with identified inputs and releases; and interpreting the results to help you make a more informed decision."

Sounds confusing, but you might be reading between the lines already. It's difficult to know, as a consumer, what impact a product you buy has on the environment, humans, and other animals. Most of the products we buy and use today were invented a long time ago, the process used to make each of these products were determined by how much it cost the manufacturer and not how much impact it had on the environment. That's because we were in the dark about the potential dangers of manufacturing, and today we need to basically reinvent pretty much everything.

New industrial ecology is using LCA to take a product and tear it down into it's various components. What it's made of, what process is used to make each of those components, how it's transported, how it's used, how we dispose of it, and how the company treats its employees and its community ... every thing we buy has a hidden price tag on our lives and environment. Making decisions on what to buy, or if to buy at all, can be daunting for those of us determined to make a difference. By remaining uneducated on what we buy, we're creating potential dangers for our futures.

So what can you do?

I've been doing my best to research what I buy. As some of you know, we're building a house and one example, recently, is our search for a sealer for our wood floors. We did some research and found some soy-based products that were looking good. We ordered samples and tried them out and were ready to purchase the product. Then, we found a newer one recently that uses a by-product of cheese making: whey. We liked this, not only were the ingredients all natural, they were using something that was being thrown away. And, it's made locally (in our state). We love supporting Vermont-made products whenever possible.  Bonus: It actually works better than anything we tried! This took a lot more time than walking into Home Depot and asking for a floor sealer ...

Another example, when we put in our plumbing, we decided to go with PVC pipes. Copper is a nonrenewable resource, and other products were less durable so using them meant having to replace them over and over rather than buying PVC once. It's a tough choice when none of the choices are perfect.

The research is time-consuming, but worth it. It's hard to know what information to trust. The manufacturers are using all kinds of phrases to get us to think they're green such as "all natural" and "wholesome" but what is really behind the product and the company that makes it?

In researching about LCA I came across an amazing resource: GoodGuide (now in beta). Rather than rating on how well something may work, they're rated based on an LCA for that product.

So, I went to GoodGuide and looked up a common product: Cheerios. Its GoodGuide rating is 8.5. They based this on:

• Health/Nutrition Performance: 10 "This product has a good nutrition score."
• Environmental Performance: 8.1 "This company has minimal or no community-related controversies."
• Social Performance: 7.4 "This company that makes this product has an above-average score in use of resources."

But it also gives a lot of deeper information and not just an overview. I looked into the Environmental Performance and found that it rated very well in Energy Management, but not as well for Compliance and Toxic Waste. For Social Performance, Cheerios rated "Best in Category" in Working Conditions & Benefits and Philanthropy, but less well (though still not part of the "Worst in Category") in Quality & Safety, Workplace Diversity, and Labor & Human Rights.

Check out GoodGuide's information on their Ratings and Methodology. And their blog.

And please check out what you're buying and maybe you'll find something better? I know I'll be spending a lot of time on this and from my initial look-through, will be replacing a lot of what I buy with something better.
