Good question, keeping is probably more environmentally friendly. I&#x27;m not sure about the second hand market. As by buying one there, you&#x27;d give the previous owner some capital and him selling in the first place, could indicate that this capital will be used for a new phone. So what&#x27;s the chance that the former owner will buy a fairphone? If it&#x27;s lower than yours, you&#x27;d better buy a fairphone yourself. (in terms of environmental impact)
