Comité français des aérosols
Air protection Evironnement protection and substainable developpment are the main goals of CFA's actions. Whith its members and partners either associative or public, CFA makes sure that aerosol is not bad for the environnement, in its production process, nor in its product itself. Ozone layer
In the ‘70s, scientists specializing in the atmosphere voiced their fears about the harmful effect of chlorofluorocarbons (CFC) used by the refrigeration industry, in plastic foams and as gas propellants in some aerosols.
According to these scientific theses, CFCs were harmful for the stratospheric ozone layer surrounding the Earth and protecting us against ultraviolet rays.
In response to these fears, the aerosol industry was the first to take action by significantly reducing (-35%) its use of such substances.
After signing the Montreal protocol (United Nations Environment Programme), the aerosol industry went a step further and stopped using chlorinated gas propellants for good.
In accordance with the provisions of the Montreal protocol, the aerosol industry also abandoned all the other substances that were regulated for ozone layer protection (HCFC).
Liquid or compressed gases currently used in aerosols have no impact on the stratospheric ozone layer.
Global warming
For many years now, the international political and scientific community has been concerned about global warning that could result from human activities.
In 1992, the United Nations Convention in Rio de Janeiro on climate change was adopted.
In 1997, as part of the resulting Kyoto protocol, developed countries (USA, Canada, the European Union countries, etc.) undertook to reduce the rates of greenhouse gas emissions by 5% in 2010 compared to 1990. So far, the United States have gone back on their commitment and refuse to ratify the protocol.
This reduction in emissions concerns six gases: carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4), sulphur hexafluoride (SF6), hydrofluorocarbons (HFC) and perfluorocarbons (PFC).
Aerosol manufacturers are little affected by the feared global warming phenomenon.
Only HFC-type gases are used in small amounts as they are the only alternative to the use of CFCs in drug-containing or in certain technical aerosols.
The contribution of aerosols to the greenhouse effects is considered to be insignificant: 0.04% of total emissions.
However, the aerosol industry agreed to help to stabilise, or even reduce the use of greenhouse gases. The use of HFCs is now limited to a small number of applications and must remain as such in the future. They are for example used in applications requiring non-flammable properties and for which there are no other technically feasible, economical and environmental-friendly solutions. It must also be said that by stopping the use of CFCs, the industry has already played a significant part in the fight against global warming.
Volatile organic compounds (VOC)
Les composés organiques volatils sont des substances qui peuvent s'évaporer dans l'atmosphère. En présence de lumière, ils réagissent avec les oxydes d'azote pour former de l'ozone troposphérique.
Les augmentations de concentration en ozone peuvent avoir des conséquences graves sur la santé humaine (troubles respiratoires …) ainsi que sur la végétation.Dans les aérosols, il s'agit de propulseurs et de solvants tels que les hydrocarbures, le diméthyléther, l'alcool éthylique, etc...
Bien que non concernés par les réglementations en vigueur, les fabricants d'aérosols se préoccupent de diminuer autant que possible ces émissions polluantes, tout en conservant le niveau de qualité des produits.
Des études ont montré que la part des aérosols dans les émissions totales de COV ne représentent que 1,9% de l'ensemble des émissions biogéniques et anthropogéniques ; il s'agit donc d'une contribution extrêmement faible.
