We must address short lived climate pollutants such as black carbon".
UNEP has led this agenda with its Climate and Clean Air Coalition to Reduce Short-Lived Climate Pollutants.
Reducing short-lived climate pollutants is essential for slowing the pace of climate change in the near term.
The others – collectively know as short-lived climate pollutants or SLCPs – create a burst of warming that is powerful but brief.
Known as short-lived climate pollutants, they include fine particles of black carbon, or soot, emitted from diesels and burning wood, and from ozone.
More ships bring more chance of major accidents and will mean more climate pollutants on the back of more melting of the ice," said Ben Ayliffe, Arctic campaigner with Greenpeace.
In 2012, six countries and the United Nations Environment Programme created the Climate and Clean Air Coalition to cut emissions of soot, methane and other so-called "short-lived" climate pollutants.
Both are "short-lived climate pollutants" that exist locally in the atmosphere for weeks to months, with ozone damaging plants' leaves and black carbon reducing the amount of sunlight they receive.
Governments and private sector leaders have unveiled achievements and plans in a variety of areas where we feel we can make the quickest, greatest impact, including energy, cities and transport, finance, resilience, agriculture and short-lived climate pollutants.
The Obama administration began an important effort to reduce these pollutants when Secretary of State Hillary Rodham Clinton began the global Climate and Clean Air Coalition to Reduce Short-Lived Climate Pollutants earlier this year.
Instead, ministers from 25 countries will co-operate to vastly reduce black carbon (better known outside these talks as soot), as well as methane and ozone in the atmosphere – substances known collectively as short-lived climate pollutants.
