Climate Change Litigation and Environmental Justice in Pakistan: Lesson from Singapore

Abstract

Climate change has emerged as one of the greatest threats to humanity in the twenty first century, disproportionately affecting developing countries such as Pakistan. Despite contributing less than 1% to global greenhouse gas emissions, Pakistan remains among the countries most vulnerable to climate disasters, including floods, droughts, heatwaves, glacier melting, and water scarcity. The devastating 2022 floods in Pakistan, which affected more than 33 million people, highlighted the urgent need for effective climate governance and environmental justice mechanisms. Climate change litigation has therefore become an important legal instrument through which citizens, activists, and courts seek accountability from governments and corporations for environmental harm and failure to fulfill constitutional and international obligations. This research examines the role of climate change litigation in promoting environmental justice in Pakistan and comparatively analyzes the governance model of Singapore. Singapore primarily relies on strong administrative governance, effective implementation mechanisms, sustainable urban planning, and strict environmental regulation instead of judicial intervention. The study aims to identify the weaknesses in Pakistan climate governance system and explore how lessons from Singapore can improve institutional efficiency, environmental protection, and climate accountability in Pakistan. This research explores the intersection of climate change litigation and environmental justice within Pakistan's legal framework, using Singapore advanced environmental governance as a comparative benchmark. Pakistan, being one of the most climate-vulnerable nations, faces unique challenges such as glacier melting and floods, which excessively affect marginalized communities. While Pakistan has seen landmark judicial activism (Asgar Leghari v. Federation of Pakistan), it lacks the rigorous legislative implementation seen in Singapore. This study utilizes a comparative qualitative methodology to analyze how Singapore "Green Plan 2030" and "Carbon Pricing Act" can provide a roadmap for Pakistan to move from judicial orders to institutionalized climate justice.
