The Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC) provides the latest comprehensive evaluation of the factors driving climate change. Regarding short-lived climate pollutants (SLCPs), AR5 finds larger contributions to climate change from methane and carbonaceous aerosols than the previous IPCC assessment while noting that uncertainties in the influence of aerosols remain large
Through text and colorful graphics, this publication explains short-lived climate pollutants and their effects on climate, health and agriculture. Time to Act also offers 16 measures to reduce black carbon and methane, two of the most potent SLCPs, details why the measures are beneficial, and describes the overall advantages of SLCP mitigation.
...of the first global effort to treat short-lived climate pollutants as an urgent and collective challenge.
The Climate and Clean Air Coalition to Reduce Short-Lived Climate Pollutants began in February 2012 with 7 partners. Today it has 80. With its rapid growth, this global effort to reduce emissions of black carbon, methane and many hydrofluorocarbons has already touched numerous sectors of society in the effort to slow the rate of global warming and protect human health, agriculture and the environment.
"Air pollution is the biggest environmental health problem and is affecting everyone from developing and developed countries, rich and less rich," said Maria Neira, Director of Public Health and the Environment for The World Health Organization (WHO).
The CCAC has played an important role in moving East Africa toward cleaner diesel fuel that is lower in sulphur and closer to world standard. Until recently, the diesel sulphur levels in this region ranged between 5,000 parts per million (ppm) and 10,000 ppm. Compare this to US and Europe standards of 10-15 ppm. In the past, the region relied on fuel supplies from a refinery in Kenya as well as from direct imports.
A new CCAC campaign on air pollution and health.
Beginning soon, the CCAC will launch a worldwide campaign to highlight air pollution, both indoor and outdoor, as a major cause of health problems. As the World Health Organization announced on March 25, air pollution is now the world's largest single enironmental health risk, causing approximately 7 million premature deaths worldwide in 2012.
The CCAC has always focused strongly on climate change as a major effect of emissions of short-lived climate pollutants, but no less important is disease. The newly constituted CCAC Health Task Force, led by the World Health Organization and the government of Norway, will lead the CCAC in raising the visibility of this important issue.
