Driving to every single household on this sparsely populated and often remote island is no easy task and creates logistical and environmental issues.  But my next guest decided to make every An Post vehicle have zero emissions.  No mean feat when we’re talking about hundreds of them.  In fact the national postal service aims to be net zero by the end of this decade. And it is for that reason as well as the fact that An Post consistently wins prizes for its working environment and trust among the public, that this month's Repak ‘Green Business person of the Month’ is David McRedmond, the Chief Executive of An Post.
