N20 = Nitrous oxide molecules stay in the atmosphere for an average of 121 years before being removed by a sink or destroyed through chemical reactions. The impact of 1 pound of N2O on warming the atmosphere is 265 times that of 1 pound of carbon dioxide. Globally, 40% of total N2O emissions come from human activities.

Carbon dioxide (CO2) is a greenhouse gas. This means that it causes an effect like the glass in a greenhouse, trapping heat and warming up the inside. This effect is important: without the CO2 that naturally exists in the atmosphere, Earth might be too cold to support human life.

CH4 = Methane, is a powerful greenhouse gas. Over a 20-year period, it is 80 times more potent at warming than carbon dioxide. Methane has accounted for roughly 30 per cent of global warming since pre-industrial times and is proliferating faster than at any other time since record keeping began in the 1980s.

Can you identify these 7 GHGs ?

Greenhouse gases (GHG) are atmospheric components that trap heat and contribute to the greenhouse effect, leading to global warming and climate change. These gases, such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), allow sunlight to enter the Earth's atmosphere but prevent some of the outgoing heat from escaping into space. As a result, they act like a blanket, trapping heat and raising the Earth's average temperature. This warming effect can have significant environmental consequences, including rising sea levels, altered weather patterns, and impacts on ecosystems and human activities worldwide.

But can you identify each of the GHG in our picture? And can you describe how each effects climate change ? Pop your answers in the comments box below or email us !

PCFs = Perfluorocarbons (PFCs) are synthetic greenhouse gases with high global warming potentials (GWPs) and long atmospheric lifespans. Used in industrial processes like

semiconductor manufacturing and aluminium production, PFCs can persist for hundreds to thousands of years, accumulating in the atmosphere and contributing to climate change. Unlike natural gases, PFCs lack natural sources or sinks. Efforts have been made to regulate and reduce PFC emissions, with some applications transitioning to alternatives with lower GWPs. Minimizing PFC use, adopting alternative technologies, and implementing proper handling and disposal practices are crucial for mitigating their climate impact.

SF6 = Sulphur Hexaflouride. Sulfur hexafluoride (SF6) is a potent greenhouse gas known for its high global warming potential (GWP). Here's how it contributes to climate change:

Extreme Global Warming Potential: SF6 has an extremely high GWP, approximately 23,500 times greater than carbon dioxide (CO2) over a 100-year period. This means that one ton of SF6 has the warming potential equivalent to 23,500 tons of CO2.

Addressing the environmental impact of SF6 is crucial for mitigating climate change. Increasing efforts are being made to minimize SF6 usage and develop alternative technologies. The adoption of more environmentally friendly gases and equipment, as well as improved handling and leak detection practices, can help reduce SF6 emissions and contribute to a more sustainable future.

HFCs = Hydrofluorocarbons. Hydrofluorocarbons are synthetic greenhouse gases commonly used in various applications, including air conditioning, refrigeration, and aerosol propellants. While HFCs were developed as alternatives to ozone-depleting substances like chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), they still contribute to climate change. Here's how:

Greenhouse Effect: Like other greenhouse gases, HFCs trap heat in the Earth's atmosphere, leading to the greenhouse effect. They have high global warming potentials (GWPs), meaning they can trap significantly more heat than carbon dioxide (CO2) over a specific timeframe.

Long Lifespan: HFCs have long atmospheric lifetimes, which allows them to persist in the atmosphere for years or even decades. This longevity increases their potential for accumulating and contributing to global warming over time.

Energy Efficiency Trade-offs: HFCs are often used in energy-intensive applications such as refrigeration and air conditioning. While they provide effective cooling, the energy demand associated with their use can lead to increased greenhouse gas emissions from fossil fuel combustion, exacerbating climate change indirectly.

Replacing Ozone-Depleting Substances: The phase-out of ozone-depleting substances, such as CFCs and HCFCs, has led to the increased use of HFCs as replacements. While this transition has been beneficial for the ozone layer, it has unintentionally contributed to climate change due to the high global warming potentials of HFCs.

NF3 = Nitrogen Trifluoride. NF3 is an inorganic, colorless, non-flammable, toxic gas with a slightly musty odor. It finds increasing use within the manufacturing of flat-panel displays, photovoltaics, LEDs and other microelectronics. Nitrogen trifluoride is also an extremely strong and long-lived greenhouse gas. Its atmospheric burden exceeded 2 parts per trillion during 2019 and has doubled every five years since the late 20th century.

Nitrogen trifluoride (NF3) is a potent greenhouse gas that can contribute to climate change. While it is not as well-known as carbon dioxide (CO2) or methane (CH4), it has a significant global warming potential.
