We present calculated rate coefficients for ro-vibrational transitions of COin collisions with H atoms for a gas temperature range of 10 K $\leq T \leq$3000 K, based on the recent three-dimensional ab initio H-CO interactionpotential of Song et al(2013). Rate coefficients for ro-vibrational $v=1,j=0-30\rightarrow v'=0, j'$ transitions were obtained from scattering cross sectionspreviously computed with the close-coupling method by Song et al(2015).Combining these with the rate coefficients for vibrational $v=1-5 \rightarrowv' < v$ quenching obtained with the infinite-order sudden approximation, wepropose a new extrapolation scheme that yields the rate coefficients forro-vibrational $v=2-5,j=0-30 \rightarrow v',j'$ de-excitation. Cross sectionsand rate coefficients for ro-vibrational $v=2, j=0-30 \rightarrow v'=1,j'$transitions calculated with the close-coupling method confirm the effectivenessof this extrapolation scheme. Our calculated and extrapolated rates are verydifferent from those that have been adopted in the modeling of manyastrophysical environments. The current work provides the most comprehensiveand accurate set of ro-vibrational de-excitation rate coefficients for theastrophysical modeling of the H-CO collision system. Application of thepreviously available and new data sets in astrophysical slab models shows thatthe line fluxes typically change by 20-70% in high temperature environments(800 K) with an H/H$_2$ ratio of 1; larger changes occur for lowertemperatures.
