The Montreal Protocol – the first treaty to be ratified by every United Nations country – regulates nearly 100 man-made chemicals called ozone-depleting substances (ODSs), says EurekAlert.
While the main aim was to preserve the ozone layer, ODSs are also potent greenhouse gases, so the deal has slowed global warming.
