About 22 billion pairs of shoes are manufactured globally each year, the production process emitting enormous amounts of carbon dioxide, enough to contribute about 1.5 percent of the world’s greenhouse gas emissions. Taking the term carbon ‘footprint’ rather too literally, product designers want to reduce impact brought about by production of shoes. Made out of plant-based materials, these shoes designs are biodegradable and do not introduce any chemicals to the earth when they are thrown away.
