「環境正義」是近年來國際間普遍推崇的環境典範。然而，在高舉環境價值的今日，各種環境思想文獻如雨後春筍般湧現，與環境正義語彙相似度極高的「環境主義」以及「生態正義」，也常出現在相關的環境論述中，往往令人難以分辨這些環境理念彼此之間的關係，本文擬對此作一釐清，並深入探究環境正義理念的發展脈絡。首先將針對「環境主義」到「環境正義」的發展脈絡進行闡釋與解析，並且探討環境正義概念的內涵以及環境正義是否能夠滿足世人以它做為環境典範的期待；其次，澄清「生態正義」與「環境正義」概念，並探討對自然行正義的「生態正義」的合理性；最後則探討環境議題做為正義論域的擴展行動究竟是一項語詞誤用或是正義理念在概念史上一次成功的演化。

“Environmental Justice” is a worldwide environmental paradigm in recent years. However, as environmental value are highly recommended today, environmental literature has been sprung up with some terms that we are familiar but not exactly savvy. Environmentalism and Ecological Justice, which with high similarity to Environmental Justice found in many environmental discourses, are hard to differentiate the meaning. This paper aims to clarify all of these and explores the idea of Environmental Justice in depth. First, I will explain and analyze the evolution of the context from “Environmentalism” to “Environmental Justice”, enquiring the connotation of Environmental Justice concept and exploring if Environmental Justice can meet people's expectation as an environmental paradigm. Secondly, I will try to explore a major difference between the definition of Environmental Justice and Ecological Justice, and to justify the conception of “Ecological Justice”. Finally, I will focus on this question—Is Environmental Justice a misnomer or a successful evolution in the history of the idea of justice?
