Fast action under the Montreal Protocol can limit growth of HFCs, prevent up to 100 billion tonnes of CO2-eq emissions by 2050, and avoid up to 0.5°C of warming by 2100.

A global phase-down of hydrofluorocarbons (HFCs) under the Montreal Protocol will drive the development of super-efficient air conditioning and refrigeration that in turn reduces energy use and carbon dioxide pollution, according to representatives from the global air conditioning and refrigeration industry, meeting 30-31 June in Bangkok to show

This Climate Action Tracker update shows that current emissions and policies - and future emission trends - are likely to lead to higher 21st century emission levels than previously projected. This, in turn, implies a higher level of warming by 2100.

Montreal Protocol, the multilateral treaty to protect the ozone layer, has been a successful environmental agreement. But an impasse over restricting the use of extremely potent greenhouse gases marred the Protocol’s 25th anniversary celebrations on September 16, 2012.

A report to the 18th session of the Conference of the Parties to the United Nations Framework Convention on Climate Change. Hydrofluorocarbons (HFCs) are man-made fluorinated gases (F-gases) developed and commercialised to replace CFCs, HCFCs and other chemicals that deplete the ozone layer.

The amount of greenhouse gases in the atmosphere reached a new record high in 2011, according to the World Meteorological Organization. Between 1990 and 2011 there was a 30% increase in radiative forcing – the warming effect on our climate – because of carbon dioxide (CO2) and other heat-trapping long-lived gases.

This report provides a summary of short-lived climate pollutants (SLCPs), including: an introduction to SLCPs; explanation of the co-benefits of reducing SLCPs with respect to climate, human health and food security; and a menu of mitigation options for reducing SLCPs, including international and regional initiatives, such as the Climate and Cle
