The Himalayas - SLCPs in High Elevation Regions The Himalayas - SLCPs in High Elevation Regions
SLCPs, especially BC and co-pollutants, are major contributors to the South Asian atmospheric brown cloud, with important consequences for monsoon rainfall and glacier retreat. Fast action on SLCPs could help slow the rate of warming over the Himalayan-Tibetanplateau, with multiple benefits for public health, food security and disaster risk reduction.

Effects on Public Health - Air Pollution, a Preventable Risk Effects on Public Health - Air Pollution, a Preventable Risk
SLCPs, particularly O3 and BC and co-pollutants, which are important parts of PM2.5 air pollution, are harmful to human health. Globally, PM2.5 is a major global cause of premature mortality. Indoor and outdoor PM2.5 air pollution are the fourth and seventh leading risk factors for early mortality globally. In 2010 indoor and ambient outdoor particulate matter pollution were estimated to have caused over 3.5 and 3.2 million premature deaths respe...

What are Short-Lived Climate Pollutants? What are Short-Lived Climate Pollutants?
SLCPs are substances with a relatively short lifetime in the atmosphere – a few days to a few decades – and a warming effect on near term climate. The main SLCPs are BC, CH4, tropospheric O3, and many HFCs. A reduction in SLCP emissions will quickly have a major positive effect on public health, agriculture in addition to the short-term mitigation of climate problems.

Emissions to air Emissions to air
Emissions of mercury from ASGM reported for 2010 are more than twice those reported for 2005. While the higher price of gold and increased rural poverty may indeed have caused more activity in this sector, the increased emissions estimates are thought to explained mainly by better data (UNEP, 2013).

Energy efficiency generally improves with economic growth...but greenhouse gases increase too Energy efficiency generally improves with economic growth...but greenhouse gases increase too
In 1992 76 million people living in urban areas were exposed to air pollutant concentrations exceeding WHO guidelines. In developing countries 1.9 million people die each year because of indoor air pollution exposure and 500,000 die as a result of outdoor pollutant levels.
