Buff has become a founding member of the Climate Action Corps, a movement promoted by the Outdoor Industry Association (OIA) that seeks to remove toxic residues from the natural environment. Accordingly, the Spanish neckwear and headwear brand will be measuring and reporting annually on the carbon footprint and greenhouse gas emissions of its manufacturing, distribution and sales operations, while laying out a plan to reduce them. The OIA has recruited 60 companies worldwide for the project. For the past several years, Buff has been working on its Do More Now program to make its production more efficient, to trade PET-derived fibers for traditional fibers, and use merino wool from suppliers who guarantee the well-being of their sheep.
