Here are details from an unpublished internal investigation by a major European operator re failure to apply low temperature altimeter correction for take-off.

When operating from an airfield in Norway which only provided advisory ATC, an EGPWS alert was given after take off during the flap retract level segment (2500ft aal). The altitude error was approx 500ft low; (-32C at 2500ft above altimeter setting reference) local terrain SSAs 6000-7500ft!

The significant issues here are:
Uncontrolled airport, no ATC to apply the correction or adjust cleared altitudes.
No specific SID identifying terrain clearance.

Do not forget takeoff corrections for these circumstances.
