Have you ever wondered about the true environmental impact of timber?
Below is a table summarizing the energy consumed in the production of timber and its three largest competitors. Apart from the fact that Australian Treated Pine sources all its timber from Sustain ably managed pine plantations, when you purchase a piece of treated pine, you are buying a piece of timber that has artificially extended durability, that has to be good for the environment! That’s why we say that “timber preservation is conservation??? It stands to reason that if you buy a piece of timber that has a life expectancy longer than that of any of the native Australian species, you will be ultimately using less timber in the long term.
The table below clearly shows that timber consumes less than 35,000% (yes that’s not a misprint!) of the energy used to manufacture the equivalent volume of steel, (lets not even mention Aluminum). You will also note the difference in the carbon footprint (carbon released) and note that timber is the only product available that stores carbon subsequent to manufacture. If you are at all concerned for the environment, your choice should be obvious.
