To this end, the EPA must ensure that the new rulemaking sets dates for removing as many of the remaining high global warming potential (GWP) alternatives to ozone depleting substances (ODS) as possible.
HFCs have been commercialized to replace the chemicals that were destroying the ozone layer, but while HFCs do not destroy ozone, they have extremely high global warming potentials and are contributing to global climate change.
Many fluorinated gases have very high global warming potentials (GWPs) relative to other greenhouse gases, so small atmospheric concentrations can have proportionately large effects on global temperatures.
Old style refrigerants with especially high global warming potential (as pictured above) are common here because here is where we need air conditioning.
This paper by NRDC, CEEW and IGSD explores the energy efficiency and power sector benefits of air conditioning companies in India to «leapfrog» and phase down unsustainable technologies based on chemicals like HFCs with high Global warming potential and move to a future based on climate - friendly and energy - efficient refrigerants.
«It is ironic that high concentrations of molecules with high global warming potential (GWP), the worst - case scenario for Earth's climate, is the optimal scenario for detecting an alien civilization, as GWP increases with stronger infrared absorption and longer atmospheric lifetime,» say the authors.
The EU Regulation on fluorinated greenhouse gases requires the refrigeration and air conditioning sectors to phase out the use of refrigerant gases with a high global warming potential by 2030.

In a letter to the United Nations body overseeing the Montreal Protocol, Daniel A. Reifsnyder, a senior environmental official at the State Department, said the administration believed the chemicals were not a direct threat to the ozone layer but «pose a very significant further threat to the climate system because of their high global warming potential
Enhance Cooperation on Hydroflurocarbons (HFCs): Building on the historic Sunnylands agreement between President Xi and President Obama regarding HFCs, the United States and China will enhance bilateral cooperation to begin phasing down the use of high global warming potential HFCs, including through technical cooperation on domestic measures to promote HFC alternatives and to transition government procurement toward climate - friendly refrigerants.
N2O has a high global warming potential of around 270 times that of carbon dioxide and is a major destroyer of the ozone.
With many HFC replacements also having a high global warming potential (GWP), a new EPA scheme to restrict alternative to those with low GWPs only, could make a dent in their growth.
Methane has a high global warming potential and is easily generated, even from rice straw left in rice paddies.
While HFCs are not Ozone Depleting Substances (ODS) and therefore an acceptable substitute for chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) under the Montreal Protocol, they have high global warming potentials (GWPs) and contribute to greenhouse gas (GHG) emissions.
However, because of the high global warming potential of methane (CH4, the major component of NG), climate benefits from NG use depend on system leakage rates.
Because of its long life span and high global warming potential (GWP), even a relatively small amount of SF6 can impact the climate.
Whilst the emission of greenhouse gases generally is the main contributor to global warming, synthetic refrigerants like HFCs have the highest Global Warming Potential of all.
As the EPA works to finalize a proposed rulemaking prohibiting the use of high global warming potential (GWP) hydrofluorocarbons (HFCs) in certain end - uses, two primary questions are raised: Will the EPA produce a rule making...
The Montreal Protocol has a lot more to offer than a model for addressing global warming emissions, it is itself an important tool that urgently needs to be strengthened to harvest the «low hanging fruit» of phasing out hydrofluorocarbons (and HCFCs), the high global warming potential ODS alternatives with genuinely climate friendly natural refrigerant solutions.
An organic carbon decomposition model, calibrated with laboratory incubations, indicates a greater production rate of CO2 - C equivalents from waterlogged (compared to drained) permafrost soils, when the higher global warming potential of methane is factored in.
The higher global warming potential of lower - emitting greenhouse gases significantly increases their contributions to the greenhouse effect.For example, over a 100 - year time horizon, nitrous oxide is 310 times more effective than carbon dioxide at trapping heat in the atmosphere.
It is common for the foam manufacturing industry to use blowing agents that contain hydrofluorocarbons (HFC) which have high global warming potentials.
EG: Ideally, we would immediately begin curtailing use of chemicals recognized as endocrine disruptors, carcinogens, and mutagens — as well as those with high global warming potential — and enact measures that would ensure we don't replace these substances with others with such hazards.
For example, nitrogen trifluoride has a high global warming potential (GWP) but is only present in very small quantities.
Cyclic perfluorocarbon radicals and anions having high global warming potentials (GWPs): Structures, electron affinities, and vibrational frequencies
The greatest source of HFCs, and the greatest source of any high global warming potential gas, is leakage from refrigeration and air conditioning equipment.
