We present the measurement of inclusive differential $\pi^0$ yields in p+p and centrality-selected Pb+Pb collisions at $\sqrt{s_{NN}}=\mathrm{\,2.76 TeV}$, using the large-acceptance ALICE Electromagnetic Calorimeter (EMCal). The recently completed EMCal enhances ALICE capabilities for the study of jets, neutral mesons, electrons, and direct photons. The EMCal acceptance (110 degrees in azimuth, $|\eta|\lt 0.7$) and high granularity enable the reconstruction of neutral mesons over a wide transverse momentum range, employing invariant mass, shower-shape, and conversion techniques. We present first measurement of $\pi^0 R{_AA}$ for both peripheral and central Pb+Pb collisions, normalized by the $\pi^0$ yield measured in p+p collisions at $\sqrt{s_{NN}}=\mathrm{\,2.76 TeV}$.
