Study finds global emissions of several banned ozone-destroying CFCs are increasing

Green Car Congress

New analysis has found increasing emissions of several ozone-depleting chemicals despite their production being banned for most uses under the Montreal Protocol—and a loophole in the rules is likely responsible. According to the researchers, emissions from these CFCs currently do not significantly threaten ozone recovery.

Study finds carbon emissions benefits of reduction in oil demand depend on size of drop and global oil market structure

Green Car Congress

Previous models have treated oil producers’ carbon footprint as if all barrels of oil are exactly the same, but with novel extraction technologies there is a great deal of variability in the global oil supply. Everyone knows about these market structures, but by considering it, we show the structure is very important in a global economy.
