  We calculate the 2 post-Newtonian correction to the radiation reaction
acceleration for non-spinning binary systems, which amounts to the 4.5
post-Newtonian correction to Newtonian acceleration. The calculation is carried
out completely using the effective field theory approach. The center-of-mass
corrections to the results are complicated and are discussed in detail.
Non-trivial consistency checks are performed and we compare with corresponding
results in the literature. Analytic results are supplied in the supplementary
materials.
