Hydrofluorocarbons (HFCs) Hydrofluorocarbons (HFCs)
HFCs are man-made fluorinated greenhouse gases rapidly building up in the atmosphere. They are used as replacements for ozone-depleting substances (ODS) in air conditioning, refrigeration, foam-blowing, fire retardants, solvents, and aerosols.

Tropospheric Ozone (O3) Tropospheric Ozone (O3)
Tropospheric Ozone (O3) is a major air and climate pollutant. It causes warming and is a highly reactive oxidant, harmful to crop production and human health. O3 is known as a `secondary´ pollutant because it is not emitted directly, but instead forms when precursor gases react in the presence of sunlight.

Methane (CH4) Methane (CH4)
Approximately 60% of methane is emitted from human activities. Methane is one of the most significant drivers of climate change, as well as the main precursor of tropospheric ozone, a powerful greenhouse gas and air pollutant. Ozone has been estimated to cause around 150,000 deaths annually worldwide and affects the health of many more.

Black Carbon (BC) and Co-pollutants from Incomplete Combustion Black Carbon (BC) and Co-pollutants from Incomplete Combustion
Black carbon (or soot) particles are formed from the incomplete combustion of biomass and fossil fuels. It is a powerful climate forcer and dangerous air pollutant. BC and co pollutants make up the majority of PM2.5 air pollution which is the leading environmental cause of poor health and premature deaths. Indoor and outdoor PM2.5 air pollution are estimated to have caused over 3.5 and 3.2 million premature deaths annually.

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.

Waste collection in Curitiba Waste collection in Curitiba
In the 1980s severe hygienic problems plagued parts of Curitiba where housing development was uncontrolled. The winding streets were too narrow for council trucks and waste rotting in the open caused disease. In 1989 the council decided to act. It sent environmental education teams into affected areas where they joined forces with neighbourhood associations to organise waste collection by local people.
