Steel is high in embodied energy. Its production has a number of environmental impacts, arising from mining, processing, manufacturing, fabrication and transport. Reducing the amount of structural steel used in homes is the best way to reduce these environmental impacts. For example, cold formed steel is commonly used in house construction and is difficult to recycle. But in most applications it can be readily substituted with a more environmentally friendly material such as timber.
