The Nearby Evolved Stars Survey (NESS) is a volume-complete sample of$\sim$850 Galactic evolved stars within 3\,kpc at (sub-)mm wavelengths,observed in the CO $J = $ (2$-$1) and (3$-$2) rotational lines, and the sub-mmcontinuum, using the James Clark Maxwell Telescope and Atacama PathfinderExperiment. NESS consists of five tiers, based on distances and dust-productionrate (DPR). We define a new metric for estimating the distances to evolvedstars and compare its results to \emph{Gaia} EDR3. Replicating other studies,the most-evolved, highly enshrouded objects in the Galactic Plane dominate thedust returned by our sources, and we initially estimate a total DPR of$4.7\times 10^{-5}$ M$_\odot$ yr$^{-1}$ from our sample. Our sub-mm fluxes aresystematically higher and spectral indices are typically shallower than dustmodels typically predict. The 450/850 $\mu$m spectral indices are consistentwith the blackbody Rayleigh--Jeans regime, suggesting a large fraction ofevolved stars have unexpectedly large envelopes of cold dust.
