Canada’s highest court is set to decide today whether it will hear arguments in a trailblazing climate change lawsuit that could clarify whether governments are constitutionally required to tackle planet-warming emissions.

The decision could set the stage before the Supreme Court of Canada in a case where seven young people have challenged Ontario’s weakened climate target.

The group has argued the revised target commits the province to dangerously high greenhouse gas levels, in a way that jeopardizes their right to life and forces them to bear the brunt of future climate impacts.

The case is the first in Canada where a court, in a full hearing, considered whether a government climate plan could violate the Charter of Rights and Freedoms.
