As consumers become more educated about what they buy, sustainably-harvested products have gained a following, and sustainable wood products are no exception.

But how do we know we’re buying sustainable wood products? Third-party monitors such as the Forest Stewardship Council keep manufacturers and retailers honest.

The FSC, which is based in Germany, has developed a set of ten forest management principles that include maintaining the ecological functions and the integrity of forests, and observing the rights of indigenous people to manage their own lands. (Read more: FSC guidelines.)

Retailers such as The Home Depot follow sustainable wood guidelines. The home improvement chain says it’s the largest supplier of certified wood in the world.

The FSC certification process includes ongoing monitoring of forests to ensure that the properties are managed according to the FSC Principles of Responsible Forest Management.

Timber makes up a big part of the certified wood market. But other sustainable wood products include patio furniture and flooring materials.

Here’s a list of six sustainable wood products:

1. Deck furniture

EarthSource Forest Products, a San Francisco distributor and dealer of sustainable wood products, sells a collection of garden furniture that includes tables, folding chairs and lounges.

Tetra-Pak is considered a pioneer in the world of packaging, and it recently reaffirmed its commitment to responsible forestry principles. And considering the company’s reach, that commitment is no small thing.

Its packaging is used to bring milk, ice cream and soup to millions of consumers in England, Ireland, Brazil and Argentina. In 2009, the company manufactured more than 2.3 billion FSC-labeled Tetra Pak cartons.
