Researchers Find That Stratospheric Ozone Depletion Reduces Southern Ocean Carbon Uptake

Green Car Congress

Researchers in France have found that ozone depletion above Antarctica has significantly reduced the Southern Ocean’s ability to absorb atmospheric CO 2 and has also accelerated acidification of southern polar waters, despite lesser CO 2 uptake. billion tons of carbon was not taken up by the oceans.

Life cycle analysis of three battery chemistries for PHEVs and BEVs; environmental impacts higher than expected

Green Car Congress

On a per-storage basis, the team found that the NiMH technology was found to have the highest environmental impact, followed by NCM and then LFP, for all categories considered except ozone depletion potential. They also found higher life cycle global warming emissions than have been previously reported. Credit: ACS, Majeau-Bettez.
