There may of course be some costs from tighter controls on pollutants, however that does not mean we should fight those controls. SF6 is the most powerful greenhouse gas known, being 22000 times more powerful than carbon dioxide. So the 8000 tonnes produced each year would have the same effect as 176 million tonnes of CO2 if it escaped. There are 189 countries with less climate impact than that, and the total of the bottom 104 countries is lower than that!
Being such a heavy gas it should be an easy matter to capture and reuse it, which would not only save the climate but also quite a lot of money.
We need to bring down total climate impacts rapidly, and we need to see this as a business opportunity, not a threat to our businesses that we must lobby against.
Let us find a good way to control these gases, but we must control climate impact now!
