In recent years, the number of court cases around theworld raising the issue of climate change hasincreased dramatically, especially in jurisdictions that have not yet adopted effective national responsesto climate change, such as Australia and the United States. In these countries, litigation provides analternative path to encourage mitigation of the causes and adaptation to the effects of climate change.In Australia, much of the litigation, particularly the early climate change cases, has taken place in statecourts or administrative tribunals, and has focused on applying existing legislation to require governmentdecision-makers to consider future climate-associated risks in planning decisions.
