Fairphone is a Amsterdam-based company that is trying to manufacture ethical smartphones. Rare earths like tin and tantalum occur naturally in only a few regions in the world, and often, populations living in these regions are exploited to feed the world's growing demand for electronics. Fairphone ensures only ethical and certified sources of these materials make their way into their phones. Moreover, they also pay special attention to manufacturing, lifecyle of the product and worker's rights at different stages in the production of the phones.
