See "man sudoers":

       env_reset       If set, sudo will reset the environment to only 
contain
                       the LOGNAME, SHELL, USER, USERNAME and the SUDO_*
                       variables.  Any variables in the caller's 
environment
                       that match the env_keep and env_check lists are 
then
                       added.  The default contents of the env_keep and
                       env_check lists are displayed when sudo is run by 
root
                       with the -V option.  If the secure_path option is 
set,
                       its value will be used for the PATH environment
                       variable.  This flag is on by default.
