It comes weeks after the Strasbourg-based court said it would continue to fast-track a case by brought six young Portuguese activists who argue European governments aren't cutting greenhouse emissions in line with the requirements of the 2015 Paris climate accord.
The court, whose jurisdiction covers all countries that have ratified the European Convention for the Protection of Human Rights and Fundamental Freedoms, is also hearing a separate case brought by a group of elderly Swiss women.
Her client, identified only as Mex M. for privacy reasons, has Uhthoff's syndrome, which affects his muscles when temperatures rise above 25 degrees Celsius (77 degrees Fahrenheit).
“The climate crisis already severely impacts his daily life, his personal dignity and his wellbeing,” said Kroemer. Under Austrian law, inaction by the Alpine nation's legislature can't be challenged in court, meaning the case is being brought directly to the European court, she said.
Kroemer said her client's specific situation would be no hindrance to the court making a ruling that is applicable to the general public.
“In a legal context, in a strategic litigation context, it really only takes one person to make a huge difference," she said.
