Australia will join the international Climate and Clean Air Coalition to support action to reduce pollutants.

The alliance of more than 24 nations, intergovernmental organisations, the private sector and community groups is committed to rapid action to reduce the short-lived but highly potent pollution caused by methane, black carbon (soot), tropospheric ozone (smog) and hydrofluorocarbons.

Climate Change Minister Greg Combet said these pollutants could be extremely damaging to people’s health, air quality, crop yields and ecosystems as well as trapping heat in the atmosphere.

The coalition is chaired by the United States and Nigeria.

US Secretary of State Hillary Clinton welcomed Australia’s partnership, saying it would greatly strengthen the efforts against these pollutants in the Asia-Pacific.
