  We present the computation of energy-energy correlation in $e^+e^-$
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
$\alpha_{\mathrm S}(M_Z)$, hence its inclusion is mandatory for a precise
measurement of the strong coupling using energy-energy correlation.
