Vegan leather is a term used to describe artificial leather fabrics, many created through the use of acrylic, PVC, nylon or vinyl fibers. Some types of artificial leathers are made from natural materials, such as cork leather which is made from cork oak bark, or ocean leather, crafted from kelp.
Artificial leather is developed as a cheaper, more ethical, or more flexible alternative to animal leather. Due to the processes that go into creating some types of synthetic leather and the inorganic nature of the product, it is not considered environmentally friendly. Natural leather is also not considered a green material, due to the chemicals used to tan, as well as the methane released by herding cows. Pleather, naugahyde, American leather cloth, ultrasuede and Clarino are all types of artificial leather.
