概要	This study theoretically examines whether a uniform relative emission standard improves a professional sports team's competitive balance and social welfare in a professional league. Our study shows that there are cases where tightening (\textit{resp.} relaxing) such standards can improve competitive balance when the differences between the abatement cost conditions of different clubs are sufficiently small (\textit{resp.} large). Social welfare improves when the standard is slightly tougher than an unregulated emission level standard. Furthermore, social welfare also improves when the standard set to a zero-emission level is slightly relaxed.
