I've talked about reducing the number of things we buy, but sometimes, we need things. When these situations pop up, the best option is finding what has the least impact on the environment.
Eco-rate can help you determine what products are the most environmentally friendly. Along with showing you the product's environmental impact, the site can rank it by energy consumption, toxicity, price, and cost of ownership over its life cycle. The site rates numerous products, including cars, bathroom faucets, computers, dishwashers, dryers, light bulbs, paint, refrigerators, shower heads, tankless water heaters, televisions, toilets, and washers.
Finally, after seeing what Eco-rate has to say, remember to keep in mind where the item might end up after you are done with it. Ask yourself what option is most recyclable.
