Precise QCD calculations are extremely important for experiments running at LHC. Both discovery and parameter fits can profit from these calculations. Nowadays state-of-the-art computation in perturbative QCD are the ones at the Next-to-Next-to-Leading-Order accuracy. The CoLorFulNNLO substraction scheme is a possible way to carry out such computations. In my talk I introduce and show applications of this scheme at electron-positron annihilation and conclude with recent advances we made
extending the framework to hadron-hadron collisions.
