ICJ Clarifies Climate Obligations: Due Diligence as Legal Standard
The highest court in the world gave advice on what countries need to do to help stop climate change.
They said countries must try their best to stop pollution.
This means making laws to cut down on pollution, checking if big projects will hurt the environment, and working with other countries.
Countries need to keep improving these efforts.
If a country doesn't do its best, it could face legal trouble.
This advice gives everyone a way to see if countries are taking climate change seriously.
The International Court of Justice (ICJ) issued an advisory opinion on states' climate obligations.
The ICJ identified due diligence as the key legal standard for assessing climate accountability.
Due diligence requires states to take 'reasonably available' measures to prevent environmental harm.
It includes substantive obligations (reducing emissions), procedural requirements (risk assessments), and context-sensitive application.
The standard is dynamic, evolving with scientific and technological advances, holding states accountable.
