Gripped by corporate earnings season and U.S. President Donald Trump’s back-and-forth tariff policy, investors largely shrugged off a historic climate ruling from the world’s top court.
But for some, the International Court of Justice’s (ICJ) recent advisory opinion on state’s legal obligations in the face of climate change could emerge as a watershed moment for financial markets.
Günther Thallinger, a board member at Allianz
, one of the world’s biggest insurers, said that close watchers of the ICJ’s July 23 ruling described it as perhaps the most significant climate development since the 2015 Paris Agreement.
At the time, the pronouncement marked the ICJ’s first-ever opinion on climate change and laid out that climate action is not optional.
