Short-lived climate pollutants include black carbon or soot, methane, hydrofluorocarbons and tropospheric ozone, or what we think of as city smog. In addition to heating up the atmosphere, they dirty our air, make people sick and affect the ozone layer.
 The skies may look clearer these days. But don’t get too excited. Levels of smog and other short-lived climate pollutants (remember HFCs?) are still high and climbing.

The Trump administration has weakened rules limiting venting or flaring of methane from oil and gas production on public lands and requiring reporting of methane emissions from most oil and gas production. MORE

The YESAIR range of portable indoor air quality instruments from Alphasense. Critical Environment Technologies Canada Inc. CETCI) was founded by Frank and Shirley Britton in 1995. MORE

Greenhouse gases (methane, carbon dioxide, ozone, etc.) Every time a cow burps or passes gas, they release a greenhouse gas called methane. MORE

These affect natural habitats, produces acid rain and destroys the ozone layer because of global warming. These gases weaken our ozone layer and cause a lot of pollution and climatic changes. Accumulating solid waste can naturally emit harmful gases like methane that can pose a threat to the health of the surrounding neighborhood as it can cause various complications when inhaled. The environment is an important factor in sustaining flora and fauna. MORE

Nitrous oxide is a greenhouse gas and one of the main stratospheric ozone depleting substances on the planet. Widely known as “laughing gas”, used for its anesthetic effects, nitrous oxide (N2O) is also regarded as the third most important long-lived greenhouse gas, after carbon dioxide (CO2) and methane.

While CO 2 may be the greatest contributor to climate change, other gases such as methane and nitrous oxide are also responsible for creating the greenhouse effect, therefore, solutions must also focus on the reduction of these gases. The IPCC was an outgrowth of a 1987 Canadian conference which produced the Montreal Protocol , an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion.
