This study investigates the impact of the fluctuations in the extra galacticbackground light (EBL) on the attenuation of the hard $\gamma$-ray spectra ofdistant blazars. EBL fluctuations occur on the scales up to 100 Mpc and arecaused by clustering of galaxies. The EBL photons interact with high energy$\gamma$-rays via the electron-positron pair production mechanism: $\gamma +\gamma' \rightarrow e^+ + e^-$. The attenuation of $\gamma$-rays depends ontheir energy and the density of the intervening EBL photon field. Using asimple model for the evolution of the mean EBL photon density, we implement ananalytical description of the EBL fluctuations. We find that the amplitudes ofthe EBL energy density can vary by $\pm 1\%$ as a function of environment. TheEBL fluctuations lead to mild alterations of the optical depth or equivalentlythe transmissivity for $\gamma$-rays from distant blazars. Our model predictsmaximum changes of $\pm 10\%$ in the $\gamma$-ray transmissivity. However, thistranslates into marginal differences in the power law slopes of currentlyobserved $\gamma$-ray spectra. The slopes of deabsorbed $\gamma$-ray spectradiffer by not more than $\pm 1\%$ if EBL fluctuations are included.
