Given that broadband access networks are an integral part of the ICT infrastructure and that DSL is the most widely deployed broadband access technology, greening DSL has become important. The authors' recent work demonstrated a promising trade-off between data rate performance and energy conservation. However, more greening still implies possibly lower data rate, and allocating this "Price of greening" across interfering users needs to be fair. This paper proposes four formulations of fair greening in interference-limited networks, unifies them into one general representation, and develops a unified algorithm to solve them effectively.
