LISBON, Portugal — Sofia and André Oliveira, siblings and teen climate activists, did not expect much from the United Nations climate conference in Glasgow.
"Most politicians make these statements that they're going to lower emissions 60% by 2030," says André, 13. "And we want to believe that. But because of their history, we know that they really can't be very trusted."
"And so that's why we had to sue them," says Sofia, 16, "so we can give them another chance to do the right thing."
