I know it's confusing for a lot of folks to think through the whole green thing, but here's a great chart from the folks at Green Depot. What a great way to see green.
They break it down into 5 categories making it easier to wrap your head around the whole concept.
Air Quality -- make choices that promote healthy air in your home.
Conservation -- protect resources...use sustainable, rapidly renewing, or products with a high recycled content. The re-use, re-claim, and re-cycle concept.
Local -- keeping it within 500 miles of home conserves energy, uses less oil for transport, and supports the local economy.
Energy -- with appliances and other systems in the home, the most energy is consumed when a product is used not manufactured so choose products that exceed Energy Star ratings.
Responsibility -- how products are made and makes a difference. Companies that manufacture responsibly and market truthfully. Let's stop the green washing.
This is good info, clear, and concise. If they have one in your area, please go visit!
