Eco-Friendly Pergola Materials: What to Look for in 2025

Almost everything has an eco-friendly alternative nowadays, and pergolas are no different. While you may think that your neighbour’s pergola made from pressure-treated lumber is an environmentally conscious choice, just wait a few seasons and watch it crumble before your eyes.

Even the best-looking pergola often ends up in a landfill after a few years. But that all changes in 2025! With a little help from Paper Crown Gallery, you can easily find materials that are actually stronger than traditional options, look better, and won’t have you replacing boards every few years.

Read on to learn more about eco-friendly pergola materials and how you can make one that delivers on both style and performance.

Hidden Costs of Traditional Materials

Most homeowners don’t think twice about grabbing pressure-treated lumber from the hardware store, but here’s what’s really happening behind the scenes.

That “affordable” wood comes loaded with chemicals like chromated copper arsenate, which slowly leaches into your soil and groundwater. Your kids play in that yard. Your vegetables grow in that soil.

And the damage doesn’t stop there, they:

• Spread Toxic Chemicals: Workers in treatment facilities face serious health risks, and the runoff contaminates local water sources for years.
• Destroys Forests: Non-certified timber usually comes from clear-cut forests and destroys ecosystems faster than they can recover.
• Creates Energy-hungry Steel: Making traditional pergola hardware generates 3.5 tons of CO2 per ton of steel, plus mining operations that scar landscapes permanently.
• Generates Microplastics: Those “maintenance-free” pergola covers break down into microplastics that end up in our food chain and water supply

And after all of that damage, you will probably end up replacing most of these materials within 7-10 years anyway. The upfront costs don’t come up when you factor in repairs, replacements, and the health costs nobody talks about.

Fortunately, we’ve moved past these with newer materials that help both the planet and your wallet in the long run.

Best Eco-Friendly Pergola Materials in 2025

After years of handling retractable roof pergolas, we’ve carefully curated a list of the best eco-friendly pergola materials for your backyard. Let’s take a quick look at them.

Option 1: Bamboo

Believe it or not, bamboo is actually stronger than most hardwoods, and it’s certainly stronger than those flimsy bamboo placemats from your local restaurant.

Bamboo has a tensile strength of 28,000 pounds per square inch, which puts it in the same league as steel. Meanwhile, your neighbor’s oak pergola maxes out at around 12,000 psi.

And the best part is that the oak tree probably took over 60 years to mature, while bamboo grows up to 3 feet in a single day. Yes, you read that right.

Drawing from our experience with bamboo installations, we’ve seen commercial structures that are still rock-solid after 15 years of harsh weather. If it’s treated well and properly installed, bamboo develops a beautiful silver-gray patina that looks like a conscious style rather than a weathered accident.

It’s also naturally resistant to insects and moisture, so you don’t have to worry about maintenance.

The only downside? It may look a bit exotic for traditional backyards. But if bamboo feels too unconventional for your taste, there’s another option that gives you the classic wood look you love.

Option 2: FSC-Certified Wood

If you still want that classic wood pergola look without compromising the environment, FSC-certified wood is the perfect material for the job.

It’s because FSC-certified timber guarantees that your boards didn’t contribute to deforestation, and the forests they came from are actually healthier because of responsible harvesting practices.

Here’s a quick comparison between the eco-friendly and regular lumber options:

Feature	FSC-Certified	Regular Lumber
Forest impact	Regenerative	Often destructive
Quality standard	Higher	Variable
Traceability	Complete	None
Worker conditions	Protected	Unregulated
Price difference	10-15% more	Baseline

The best FSC options for pergolas include cedar, redwood, and tropical hardwoods like teak.

Cedar naturally resists rot and insects, so you’re looking at 20 years of life with minimal maintenance. Redwood has that gorgeous natural color that ages beautifully, while FSC teak is practically indestructible.

Based on our firsthand experience, the 10-15% price premium disappears quickly when you factor in longevity. And you can sleep easy knowing your pergola helped fund forest restoration projects instead of clear-cutting operations.

Option 3: Recycled Aluminium

Did you know aluminum can be recycled infinitely without losing its properties? That old soda can in your recycling bin could become part of your pergola frame, and it’ll be just as strong as virgin aluminum.

It’s certainly sustainable, and nothing like those flimsy patio chairs from the 80s. It also includes:

• Modern Finishes: With new powder coating technology, even aluminium can look like wood grain, stone, or any color you want. The finish bonds at a molecular level, so it won’t chip, peel, or fade like paint does.
• Weather Resistant: While your neighbor replaces warped boards every few years, aluminum just keeps going. No rot, no insect damage, no splitting from temperature changes. That’s impressive, isn’t it?
• Energy Saving: Recycling aluminum uses 95% less energy than producing new aluminum. So, your pergola frame has a tiny carbon footprint compared to steel or even some wood options.

Modern aluminum pergolas look nothing like the industrial structures of the past, and they’ll outlast practically everything else in your yard.

Option 4: Other Eco-Materials to Consider

Sustainable building is a relatively new concept, but it’s moving fast, and 2025 is bringing some fascinating new players. These are actually available now in the market, though availability varies by region.

• Recycled Plastic Lumber: Those landfill plastic bottles are currently being turned into deck boards and pergola beams that feel surprisingly solid underfoot. The texture mimics real wood, and the color goes all the way through, so scratches don’t show.
• Hemp-Based Composites: This one sounds weird until you see it in person. Hemp fibers mixed with natural resins create boards that are naturally pest-resistant and incredibly durable. The material has a unique texture that’s almost soft to the touch, yet it handles structural loads without complaint. Also, hemp grows so fast it’s basically a weed (which, technically, it is).
• Cork Panels: While corks are perfect for accent elements or privacy screens rather than main structural components, they naturally insulate and create interesting visual patterns. It’s harvested from tree bark without killing the tree, so it’s completely renewable.

Now that you have a clear idea of the types of eco-friendly pergola materials, let’s look at how to choose the right one.

How to Choose the Right Materials

Finding the best material means that you have to be honest about your priorities instead of trying to find one “perfect” material that checks every box.

Start with your biggest concern:

• Low maintenance: Aluminum wins since it never needs treatment, staining, or sealing
• Tight budget: Bamboo gives you the most value, especially for DIY installation
• Classic wood look: FSC-certified cedar balances appearance with responsibility

Consider your climate:

• Humid areas: Skip regular wood, choose aluminum or recycled plastic lumber
• Desert/high UV: Powder-coated aluminum won’t fade like other materials
• Coastal/salt air: Aluminum handles corrosion best.

There’s no single “best” eco-material, just the best one for your needs, budget, and climate. Once you’re clear on your priorities, the choice becomes obvious.
