Halocarbons

As we learned earlier, halocarbons levels dropped since being banned in the 1990s. The phasing out of chlorofluorocarbons has removed a lot of the ozone threat and is allowing the protective ozone layer to recover. However, other problem gases, like perfluorocarbons and sulfur hexafluoride, affect the atmosphere and are given off during aluminum smelting, production of electricity, magnesium processing, and semiconductor manufacturing. These can be limited through different manufacturing methods, but it's a matter of economics. Until environmental concerns on excess halocarbon release are widely understood, manufacturers have little incentive to change.
