Australia is refusing to join global superpowers including the United States and the European Union in a pledge to cut methane emissions at the COP26 summit in Glasgow.

The pledge is being described as one of the key global actions required at the conference in the fight against climate change, with methane being the second largest contributor to global warming behind carbon dioxide.

Former Prime Minister Malcolm Turnbull described the decision as disappointing, as Australia’s refusal now aligns them with some of the biggest methane emitters in the world such as China, Russia, and India.
