Climate Change, Coming to a Court Near You

Climate change is the defining challenge of our time. Without urgent climate action, humanity faces a world that cannot sustain civilization as we know it. People around the globe are demanding action, some with climate litigation. This four-part report series recognizes the inevitability of increased litigation in the era of climate change and judges need a tool kit to respond. Report One explains how judges from Asia and the Pacific contribute to climate governance, along with the Asian Development Bank's rationale for producing this report series. It guides readers through some of the basics about climate change: What is causing it? How do we know? How bad might it get? What do we do about it?

Climate change in Asia and the Pacific is deadly and impacts communities now. Regional climate litigation seeks relief in increasingly urgent ways and judges need a tool kit to respond. Report Two of this four-part series is a comprehensive review of the growing number and variety of climate lawsuits in Asia and the Pacific. It underscores the unique flavor and voice of regional jurisprudence and compares it with global approaches. No one can solve climate change alone and neither can any particular judiciary. Judges can, however, learn from each other, taking judicial excellence and applying it to the case before them.

National legal and policy frameworks underpin international climate action because they are the backbone of domestic responses to the climate emergency. Unless they support global objectives, local climate action stalls. Concerned by sluggish national responses to climate change or injured by its impacts, citizens are filing lawsuits, making courts central to national climate governance. To adjudicate these lawsuits, courts require current information about their climate change legal and policy frameworks. This report provides holistic syntheses of the climate legal and policy frameworks of 32 countries in Asia and the Pacific and discusses key legislative trends and climate-relevant constitutional rights.

In 2020, the Paris Agreement is the pinnacle of international law on climate change. It orchestrates global climate action over the coming decades. Countries agreed to limit global warming to well below 2°C above preindustrial times, closer to 1.5°C. Humankind will only achieve this temperature goal if we domesticate our international climate commitments. Judges have proven to be instrumental in holding their governments accountable for their climate pledges. Report Four of this four-part series explores the nature of the Paris Agreement, its history, and the framework of international instruments and international legal principles that support global and domestic climate action.
