Look for the percentage of recyclable materials used and renewable or rapidly renewable materials use. Consider lifetime of the product, whether it meets air requirements or is GreenGuard certified, and whether the manufacturer is green. Do not buy wood, especially wood with unsafe stains or paints applied to it. Although not all wood is bad. Check into the forestry practices associated with the manufacturer. Knoll is an example of an industry leader in producing green, wood products. They also use recycled materials in some of their products.
One indicator of truly green office furniture is a GreenGuard certification. The GreenGuard Environmental Institute, GEI, is a non-profit that rates the indoor air quality of certain products. Some products have dangerous chemicals, allow for mold growth, or have other pollutants. They’re authorized developers certified by American National Standards Institute. Check out the rating system on their website at greenguard.org. The Denver office of the US EPA chose only GreenGuard certified office furniture for their new, green building. Ecowork EG is a great example of a company that is eco-friendly and produces safe, green office solutions.
