Is Teak Wood Sustainable? Everything You Need to Know

For many generations now, teak wood held a high standard of preference globally. Durable across all-weather conditions, rot and water resistance, makes it perfect no matter where you live. Be it for home or office furnishing, teak wood offers a certain elegance and luxurious look. What many may not know is that irresponsible growing and sourcing teak does more harm to the planet. Resultantly, forces the industry of woodworkers to look at alternative, sustainable options.

Simply put, teak as such is sustainable because of its carbon storage and sequencing. Yet, the question of teak sustainability largely rises from where you source the teak wood from. Many illegally produced and sourced teak, with irreversible consequences of deforestation, may make you wonder if teak really is sustainable. Not just on the ecosystem, the ill effects of teak wood deforestation also displace local indigenous communities whose livelihood depends on forest produce.

Given the debatable nature of teak wood sustainability, this article breaks down the different facets of teak usage. Including analyzing its life cycle, monitoring authority, and the carbon footprint left behind in the process of manufacturing and transportation. Whether you’re a new homeowner researching wood options or a woodworker, this article offers a one-stop solution for teak wood.

The Issue With Teak Sustainability

A product that lasts for centuries without the threat of rot and low cost of maintenance made teak a superior preference amongst woodworkers and consumers. However, growing teak is no easy feat! It takes at least 80 years to mature. This makes it not an ideal source of replenishable wood. It also degrades the entire ecosystem during deforestation. Consequently, it also increases the stress of the climate crisis.

Currently, not all forms of teak wood are legal to purchase. One particular species, famously known as common teak or, scientifically known as Tectona grandis, is the only legal and ethical species of teak wood you can buy. It is not unknown that Indonesia and Myanmar are the major suppliers of teak wood. Naturally, exporting teak from South-East Asia to the USA, UK, and China, predominantly, adds to the harmful impact on the environment.

Not to mention, the carbon footprint left behind in the process of deforestation, transportation, processing, and manufacturing of teak makes a strong argument that teak is not a sustainable option altogether. Environmentalists and forest conservation activists further note that many insects depend on the teak for food. By eradicating them using pesticides and destroying teak as a natural resource, the process affects the food chain and causes an imbalance in the environment.

Closer Look at Teak Wood Sustainability

A tropical wood, teak grows either in plantations or in forests. Commonly, teak grows up to 100 feet in height and takes up to 40 years to get here. However, where the teak grows determines the time it may take to mature. That is, in a native forest, teak may take over 80 years to mature, and around 60 years in case of growth in a plantation.

Regardless of where they grow, the method of extracting the wood for commercial use leaves an unchangeable mark on the ecosystem it grows in. Typically, teak wood goes through five stages of the life cycle – growing, manufacturing, transportation, usage, and end-of-life teak. Taking a closer look at these life stages with a sustainability lens allows us to better understand what makes teak an unsustainable option.

Life Cycle of Teak Wood

For instance, growing teak is preferable to the environment thanks to its carbon sequestration. This means that teak trees capture and store the atmospheric carbon dioxide within them. As a result, this reduces the level of carbon in the atmosphere. A viable solution to address the looming threat of climate change.

On the flip side of this, wrongful management of teak while growth can lead to severe damage. Not only to the teak trees but also to the surrounding biodiversity as a whole. This makes the cultivation of teak sit on the fine balance between doing too much good or doing too much harm. A simple misstep can make the whole process illegal. Unfortunately, this purely depends on the ethical practices of forest management.

Then comes the manufacturing of teak into products. One can argue here that manufacturing as a process does not affect the suitability aspect of teak. This is primarily because wood waste can double up as by-products or biomass. Consequently, this can help offshoot the carbon footprint left during the process of extracting teak from its source.

Next comes the transportation of teak, which emits high levels of carbon footprint in the process. Transporting teak from South East Asia to the rest of the world raises the question of whether teak is worth the immense carbon footprint it leaves in this process.

Looking at usage, there is no question here about sustainability. Since time immemorial, teak has proven to last a lifetime if maintained well. Resistant to water, rot, moisture, or damage, teak wood can outlive humans and this factor alone influenced the use of teak all these years. Finally, as the original purpose of the teak nears the end, it is easily recyclable into other products.

The Debate Around Teak Wood

Yet, the debate arises as we look at all the stages as a whole, and not as independent segments. The reliance on teak wood as a source becomes unsustainable in the long run. In simple terms, teak will take years to grow back, making it not so quick as a replenishable source. Paired with the carbon footprint left during its life cycle, one must really look at whether the damage done to the environment is worth the process.

You may wonder, why is teak even an option as a sustainable source in the first place? Two major benefits of teak tip the debate on teak sustainability. One, the carbon sequestration process of teak trees is a natural solution to climate change. In doing so, teak trees release oxygen into the air by taking in all greenhouse gases within them. Two, the usage of teak for years without any damage makes it a viable option and cost-effective.

What people most often fail to realize is that the carbon sequestration becomes meaningless if we continue the same methods of harvesting teak. The time of manufacturing teak for human use and the time it takes to grow again has a negligible effect in actually removing carbon dioxide from the air.

But, most of all, forest management plays a huge role in regulating the diminishing consequences of teak wood production. Especially in Myanmar, teak grows in a rich tropical rainforest. Needless to say, when large-scale deforestation takes place, the heavy mechanical kills the rich bio-diversity. Subsequently, this makes the rainforest inhabitable and kills all the flora and fauna without a chance for them to thrive again.

Who Monitors Teak Wood Sustainability?

To ensure an ethical regulation of forest management, various international regulatory organizations lay down ground rules. They also offer certifications to ensure the legitimacy and sustainability of the wood used. If you want to buy sustainable teak wood, look for certifications offered by either of these two renounced forest management regulators.

One such is the Forest Stewardship Council (FSC). They promote and advocate for the use of sustainable wood. Considered the world’s most trusted forest management solution, FSC pioneered ethical forest management practices, regulations, and certification processes. FSC offers certification only after considering the holistic environmental, economic, and social benefits of processing the teak.

The Programme for Endorsement of Forest Certification (PEFC) is another globally recognized certifying body for forest management. Slightly more stringent in the process of certification, PEFC looks at the effect of forest management on local farm owners. By forming a global alliance with more than 80 NGOs, trade associations, global companies, forest owners, and individuals, PEFC offers national certification. Only those providing adequate evidence of responsible and ethical practices of teak management get certified.

Other Checks for Teak Sustainability

In addition to buying teak from certified sources, you can also do your own checks to ensure the sustainability of the teak you want to buy. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), an international treaty between governments, lays down ground rules for the international trade of wild animals and plants. In doing so, the treaty ensures and regulates trade to protect endangered species. Featuring over 32800 plants as part of their endangered list, CITES features some species of teak as part of their list. We recommend you research this list to ensure the teak you are looking to source or buy does not fall under this list. If it does, then you may want to reconsider buying from a more legal and less endangered source.

Alternatively, you can also look at the IUCN Red List of Threatened Species. A simple search with the keyword teak on this platform shows many results of threatened teak sources. Finally, if you are located in the European Union and looking to buy within the region, you can also look at the EU Timber Regulation (EUTR).

In conclusion, there is no straight yes or no answer to teak being a sustainable source. While teak as such is a sustainable form of wood, human actions have raised the issue of sustainability. Illegal logging such as deforestation and illegal harvesting, along with global transportation, pose extensive irreparable damage to the environment. Given this indisputable fact, not all sources of teak are sustainable. That said, certification from these authorities is still a sustainable option to buy your teak wood!
