  We have investigated the physical properties of Planck Galactic Cold Clumps
(PGCCs) located in the Galactic Plane, using the JCMT Plane Survey (JPS) and
the SCUBA-2 Continuum Observations of Pre-protostellar Evolution (SCOPE)
survey. By utilising a suite of molecular-line surveys, velocities and
distances were assigned to the compact sources within the PGCCs, placing them
in a Galactic context. The properties of these compact sources show no
large-scale variations with Galactic environment. Investigating the
star-forming content of the sample, we find that the luminosity-to-mass ratio
(L/M) is an order of magnitude lower than in other Galactic studies, indicating
that these objects are hosting lower levels of star formation. Finally, by
comparing ATLASGAL sources that are associated or are not associated with
PGCCs, we find that those associated with PGCCs are typically colder, denser,
and have a lower L/M ratio, hinting that PGCCs are a distinct population of
Galactic Plane sources.
