There are sustainable, beautiful green flooring options for every room in your home, in a variety of materials. Here are just a few popular options.

Wood options:

• Cork floors are made from the bark of living cork trees that aren’t harmed when the bark is harvested—it regenerates, actually absorbing more carbon than a cork tree that doesn’t have its bark harvested. Many cork floors are actually made from recycled “leftovers” from wine-stopper production and have a great textural look. It’s available in a variety of colors and styles, plus cork is also a good choice for helping eliminate extra sound and it retains warmth well, too.

• Bamboo floors are made from bamboo stems which can be harvested about every six years, making them a sustainable material to gather for flooring. They’re durable and resist humidity well, provided they had time to “cure” in the space they’re going to be laid for about three days prior to installation, and they’re stronger and less expensive than hardwood floors made from other woods.

Tile options:

• Recycled glass tiles are made from at least 25 percent waste glass from windows, mirrors, bottles, jars and other post-consumer waste products, which are combined with minerals like clays and silica. They’re low-maintenance and come in a variety of sizes, colors and textures, just like non-recycled glass tiles. Old recycled glass tiles can even be recycled again and made into new recycled glass tiles, and production of recycled glass tiles can be produced using up to 50 percent less energy than other similarly-sized tiles.

• Some ceramic tiles are also being made with recycled glass and can have the look of stone or terra cotta tiles while keeping things green.

Carpeting options:

• Wool carpet is a great option for both wall-to-wall carpeting and area rugs. Wool carpet has no off-gassing and typically doesn’t use any chemicals, even on the backing, so it’s perfect for the chemically sensitive that also want something warm underfoot. Wool also wears well, and because they’re woven from a natural fiber it’s completely sustainable.

• Carpet tiles are a good idea for green families with small children. If a spill or stain occurs, simply pop the tile out and replace it with a new tile. Carpet tiles are available in both natural and synthetic fibers in several colors and styles.
