Northern hardwood is hardwood grown in temperate regions such as Europe, North America, Russia and New Zealand.

The sustainability profile of all hardwoods is similar, with good durability and low material footprint when they come from sustainably managed FSC certified forests.

The main environmental impacts of hardwood are transportation, if it comes from far, and the drying process. The most used species are birch, beech, oak, larch, maple, ash, cherry and walnut.
