In response to that particular statement, apparently you do not. There are no, as of yet, processing tools, applets, plugins, or addons that can accurately and truthfully emulate a polarizing filter.

Good morning. I know how a CP filter works and its effects.
Processing the sky in Adobe Camera Raw can include the Dehaze Filter and the new version of the Graduated Filter.
If need be, in the full Photoshop CC, a user can go the Menu Bar > Select > Color Range to select only the sky area, for further processing, to gain verisimilitude in that area.
With the sky area selected, the user can also apply the Photo Filter Adjustment to blue up the sky to eye.
These four software adjustments have made the CP Filter and the GND Filter near obsolete -- assuming a good exposure of the sky area in the camera.
But yes, if the subject contains a lot of glare off, say, plantlife or water, then a CP Filter may prove indispensable. The GND Filter, however, a user may leave at home given the software manipulations available now.
This approach does rely somewhat on the low-noise images from newer cameras, because properly exposing the sky will render the foreground underexposed. This fact requires lifting the exposure of the foreground in the software (ACR and PCC). I do this manipulation all the time and with success.
