We present the computation of energy–energy correlation in 
collisions in the back-to-back region at next-to-next-to-leading logarithmic accuracy matched with the next-to-next-to-leading order perturbative prediction. We study the effect of the fixed higher-order corrections in a comparison of our results to LEP and SLC data. The next-to-next-to-leading order correction has a sizable impact on the extracted value of 
), hence its inclusion is mandatory for a precise measurement of the strong coupling using energy–energy correlation.
