Glasgow | The Morrison government has refused to join US President Joe Biden’s initiative to cut methane emissions by 30 per cent this decade, even as more than 100 other countries backed the plan at the Glasgow COP26 summit on Wednesday.

Mr Biden told world leaders who joined him to launch the Global Methane Pledge that “one of the most important things we can do” to prevent global warming exceeding 1.5 degrees Celsius was “to reduce methane emissions as quickly as possible”.
