Elm wood is generally considered more environmentally friendly than pine wood. Elm trees have a slower growth rate, which means they sequester more carbon over their lifetime compared to pine trees. Additionally, elm wood is harder and more durable, which can lead to a longer lifespan of products made from it, reducing the need for frequent replacements and thus reducing overall environmental impact. According to the U.S. Forest Service, elm trees can store up to 1.5 times more carbon than pine trees per unit of volume.
