Tear Down that Fence: Tips to Green Your Yard With Sustainable Materials

When building your garden paradise, try a more thoughtful version of the "reduce, reuse, and recycle" motto.

Editor's note: Want a climate-friendly home? Your yard is a good place to start. This is the second听in a five-part series of guides on how to manage your outdoor turf to reduce your carbon footprint, all while creating bird-friendly habitat. Read parts one,听three,听four, and听five.

Two years ago, at a听summer family barbecue, my cousin plopped down on one of our ancient Adirondack chairs and went crashing through. The furniture came with our house, and, for 20 years, we鈥檇 been making regular repairs and painting annually to stem the rot. It was time to consider other options.

You鈥檇 think it would be easy to find a simple list of low-carbon landscape and听backyard materials. On the contrary, choosing products, whether planters, decking, or wicker sectionals, is enough to make your head spin. Faced with an array of new chair choices鈥攐ne听made from virgin materials, one听with recycled content, another made locally鈥攈ow do you determine which is best?

鈥淚t鈥檚 surprising how little information there still is,鈥 says Melissa Bilec, deputy director of the Mascaro Center for Sustainable Innovation at the University of Pittsburgh. Ideally, she says, society will one day听move beyond the current 鈥渕ake, use, and dispose鈥 linear model of consumption to a 鈥溾 that avoids waste and pollution听by recovering and restoring materials听in a continuous closed loop.

For now, though, it鈥檚 necessary to muddle through with some common sense. Try following a听more nuanced version of the traditional three 鈥淩s鈥濃擱educe, Reuse, and Recycle.

Use Living Materials

As Kim Sorvig points out in his useful tome ,听using plant materials in your garden whenever possible听provides a long list of side benefits, such as cooling shade and听carbon sequestration. For example, instead of the wooden or, worse, plastic fences that have multiplied along property lines across the country,听why not opt for a wildlife hedge? A spectacular mix of native flowering and evergreen trees and shrubs left to follow their own growth habits听can provide not only privacy but also much-needed food, nesting, and resting places for birds and other creatures.

Whittle Down Your Wish听List听

There鈥檚 a good reason why 鈥渞educe鈥 is the first of the three "Rs."听The greenhouse gas emissions involved in the so-called life cycle of any product can pile up, from the extraction of raw materials to its manufacture, transport and, ultimately,听disposal. It鈥檚 a good idea to ask yourself if you absolutely need that fully-outfitted outdoor kitchen, and pare down the plans where possible.

Reuse, Repurpose听

It鈥檚 also worth seeing whether you or a neighbor have a pile of old pavers lying around that could become a new patio. Reusing existing and salvaged materials is not only more climate-friendly than purchasing virgin resources, but often less expensive, too.

Steer Clear of Concrete

The amount of 鈥渆mbodied energy鈥 in virgin concrete is so enormous that avoiding it should be a basic rule of thumb. During manufacture, its major component, cement, must be heated in a kiln at more than 2,500 degress听Fahrenheit. Concrete is so energy-intensive to produce that it accounts for worldwide.

Look for Local Materials听

Because the fossil fuels burned during transportation can significantly increase听a product鈥檚 carbon footprint, seek out materials that are harvested, extracted, or听manufactured close to home. Is there a carpenter in your community who can purchase locally-harvested wood to build your new deck? Does a nearby supplier sell locally-quarried stone or gravel for garden paths?

Consider Certified Products听

It鈥檚 also worth checking out products that have been certified by an independent organization that has determined they meet a set of environmentally-rigorous standards. One of the best known is the , a nonprofit established in 1993 to promote sustainable management of the world鈥檚 forests. Wood bearing the FSC logo is certified for having a comparatively small impact on the environment, including on the atmosphere. Bilec recommends consulting the Green Building Alliance鈥檚听.

Explore Recycled Options

There鈥檚 also a good reason听鈥渞ecycle鈥 is the last of the three Rs. Recycled materials aren鈥檛 thrown away, but they are re-manufactured between uses. This, along with collection and transport of the materials, may more than cancel out听any net-energy savings. On the other hand, purchasing products with recycled content can boost the recycling industry, getting us closer to the ideal circular economy.

So what did we decide to do with our rickety Adirondack chairs? There was no source of local, sustainably-harvested wood for replacements, and in any case the corrosive salty听air and humidity in our coastal environment would necessitate regular applications of preservative or paint to resist rot, which have their own climate impacts. We therefore opted for chairs made from 100 percent high-density polyethylene (HDPE), primarily from milk jugs and other post-consumer plastic products. What would you have done?
