One of my favorite catalogs to shop from is Gaiam. Each time I buy something from them it is re-created, fairly traded and/or supporting  a great charity. They also have really cool things or I wouldn't want to buy their stuff.
Gaiam gives POP. That means a Portion of the Proceeds go to all sorts of charitable causes opening up all sorts of gift ideas. For any purchase you can be a Go Zero Hero and buy a go zero tree to offset your carbon footprint caused by the shipping of your gift. The replant forests and restore wildlife habitats.
Gaiam's stuff is fairly traded. It is cool stuff like jewelry, chocolate, clothing, art, home decor. When you buy it you are helping artisans around the world earn living wages and learn marketable skills.
Gaiam makes a lot of recreated stuff that helps to keep stuff out of landfills and use up valuable resources. I love the Recycled Tree of Life Wall Sculpture made from recycled oil drums and the eco fleece robe made out of recycled soda bottles.
Check out Gaiam to see a lot of cool gifts that you can give that also give back.
