In Apple's case it is mostly a labor play. They have a number of initiatives related to the environment [1]. They are trying to reduce their carbon footprint, and are close to get 100% of their power from renewable sources. They also announced their intention of a closed-loop supply chain (no new mining). Of course, they are not perfect. The Washington Post documented the horrifying exploitation of cobalt miners in Congo [2]. Some of that cobalt ended up in Apple batteries. Apple said it was addressing the issue [3]. The biggest contribution you yourself can make at this moment is to simply consume less.
