Okay, time to get scientific. There’s a lot of talk about greenhouse gas emissions right now, and people are looking at ways to reduce their “carbon footprint”.
Wanna know the easiest way? Build with wood. The production of any building material causes greenhouse gas emissions, mostly CO2, or Carbon Dioxide, which is a result of burning fossil fuels. We have to burn fossil fuels to harvest trees for lumber, dig up iron ore for steel and mine limestone and stone aggregate for concrete. Then it has to be processed into a product, another fossil-fuel burning process. Not done yet… it still has to be transported to market on, you guessed it, fossil-fuel burning vehicles. All of these processes result in CO2 emissions.
But here’s the really cool thing about wood: you can actually REDUCE CO2 emissions by simply choosing to build with wood. Blasphemy, you say? Stick with me here. Trees are known as “carbon sinks”, that is, they consume CO2 while they grow, storing the carbon and releasing the oxygen back into the atmosphere. A good thing, right? When a tree is harvested, that carbon is trapped in the final product INDEFINITELY. So, over the life of a tree, it actually takes more CO2 out of the atmosphere than is created in the process of harvesting, milling and delivering to market. The net result of building with wood is the removal of about 3/4 of a ton of CO2 emissions on average per cubic meter of product. Concrete, on the other hand, adds about half a ton of CO2 emissions per cubic meter of product. And steel? Steel adds about four tons of CO2 emissions per cubic meter of product.
So, bottom line is, using wood is better for the environment than concrete or steel. But, to be fair, not everything can be made with wood. The real key is balance. Without steel, I wouldn’t be in business. Without concrete, my shop would be sitting in the dirt. If you’re planning a building project, learn everything you can about your options. Educate yourself. And then choose the one that best fits your needs. And if it’s also the best choice for the environment, all the better!
