In this talk, construction and phenomenological implications of  the effective Hamiltonian for hadronic parity violation in strangeness-nonchanging processes will be presented. I will start with briefly discussing the motivations behind performing such a robust analysis. Next, methods and results of calculating the  anomalous dimension matrices of relevant operators in both leading order (LO) and next-to-leading order (NLO) corrections in QCD is presented.  In particular, I will detail how the existing results of studies in flavor physics can be utilized in these calculations. Further, performing a renormalization group flow of all isosectors to low energy scales (~ 2 GeV), the complete effective Hamiltonian for hadronic parity violation is constructed.  This improved effective Hamiltonian and precise non-perturbative assessments of the quark charges of the nucleon within lattice QCD  are combined to make assessments of the parity-violating meson-nucleon coupling constants. Finally, these theoretical estimates are compared and shown to be in good agreements with recent, precise measurements of hadronic parity violation in few-body nuclear reactions.
