Taiwan ratified both International Covenant on Civil and Political Rights and International Covenant on Economic, Social and Cultural Rights in March 2009. Meanwhile, an Implementation Act was passed to make all of the rights enshrined in the two Covenants directly applicable in the domestic legal regime, having become effective in December 2009. Taking advantage of such a renewed human rights moment, many attempts were undertaken to utilize the two Covenants rights into domestic public interest litigation. Against this backdrop, this paper aims at analyzing ways in which these Covenants rights may be made into and linked with environmental claims. Based upon general comments and case law of the two Covenants, this article argues that both substantive and procedural environmental human rights are available in the two Covenants. These rights include substantively, right to life, right to health, right to water, right of privacy, family right, religious right, minority rights, and procedurally, right to information, right to participation and right to judicial remedy. It is evident that international human rights have occupied a center place in domestic and transnational environmental claims. This development not only demonstrates the interrelation between environment and human rights but perhaps more importantly witnesses the convergence of domestic and international legal regimes, which deserves further scholarly attention and research.
