Be careful with environment variables. I've often seen that on some crashes all environment variables are dumped. While this should not happen in production configurations, it sometimes does. Furthermore, errors, along with the helpful debug parameters, are often sent by email and get into the hands of the wrong people (e.g. into the issue tracker where everybody has access to, including junior developers and interns who should never see production AWS keys). A better way is to store it into a config file and store them into global variables at the start of the server (while globals are normally bad, it is ok to use them for thinks like configs if you don't plan to change them after initizalization. Environment vars are globals after all).
