Europe’s highest human rights court threw out a case Tuesday brought by six Portuguese youths aimed at forcing countries to meet international obligations to reduce greenhouse gas emissions, but sided with a group of senior Swiss women who also sought such measures.

The European Court of Human Rights came down with decisions in a trio of cases brought by a French mayor, the six Portuguese youngsters and more than 2,000 members of Senior Women for Climate Protection, who say their governments are not doing enough to combat climate change.
