We’ve all had our moments of frustration with the unending negotiations on mechanisms to control carbon dioxide emissions. In the last Conference of Parties held at Durban in 2011, it was decided that the global deal for the post Kyoto framework will only be reached by 2015.
Meanwhile, the climate clock is ticking: countries continue to face the impacts of climate change with the poorest being hardest hit. Science has shed the spotlight on a “parallel track” which could help us deal with part of the climate change problem in a faster, cheaper way – it is tackling short-lived climate pollutants (SLCPs), primarily black carbon, methane, and hydrofluorocarbons (HFCs).
These pollutants, while being extremely potent in terms of their global warming potential are short-lived in the atmosphere. For example, black carbon persists in the atmosphere for about two weeks (compared to CO2 that lives for up to 100 years) and is 917 times more warming than CO2 over a 100 year timeframe (and 3,320 times over 20 years).So, action on SCLPs can help buy time in addressing the more important and longer-term greenhouse gas (GHG) emissions.
