It depends what exactly you mean by environment map.

Some 3d graphics systems use the term "environment map" for a nasty 
kluge that they use to avoid calculating reflections. POVRay calculates 
reflections correctly, so there's no need for the kluge. Apply your 
environment map pigment to the sky_sphere and allow it to be reflected.

Id you've got an environment map texture that is designed to be placed 
on a cube, then apply the texture to a large cube that contains the 
scene and apply ambient 1 (because you don't want to cast shadows onto 
the sky).

If you don't want the environment to be visible in the background of 
your scene, use the no_image keyword so that you only get reflections of 
it.
