Setting Linux environment variable for another user (sudo)

How can we set environment va开发者_开发百科riables for another user on a machine? I want to run some script with sudo -u xyz but I need to set some environment variables before running the script for xyz user which is different from my login.

You can add VAR=VALUE between the sudo -u xyz and the script. Example

sudo -u xyz LANG=C LD_LIBRARY_PATH=/usr/local/lib some_script.sh

From the env(1) man page:
