 Albedo is given by:
 $$
-\alpha=\frac{P_\text{reflected}{P_{\text{incoming}}}}
+\alpha=\frac{P_\text{reflected}}{P_{\text{incoming}}}

 This is where the Boltzmann law comes in to play. In order to calculate the emissivity of an object, you first need bot: the power of emissions from the target object, and the Power that would be emitted by a black body of the same temperature. This value can be procured using the Stefan Boltzmann Law of Radiation.
