COP28: CCS dependency to cost $1tn a year more than renewables route, study says
A new report from the University of Oxford has found that net-zero pathways heavily dependent on carbon capture and storage (CCS) will cost at least $1tn more per year than scenarios involving renewables. The report highlights the gross underestimation by countries pushing for CCS technology as a substitute for immediate emissions cuts. Transitioning to renewables to reach net zero emissions would cost at least $30tn less. The report also warned that heavy dependence on CCS would be economically damaging and called for governments to scale up investment and stick to essential use cases for CCS.

Extreme weather puts hospitals at high risk of shutdown, says study ahead of COP28 Health Day
Over 5,000 hospitals in India, the highest number in any country, are at high risk of shutdowns due to extreme weather events if fossil fuels are not phased out by the end of the century, according to a study by XDI. Worldwide, one in 12 hospitals face a similar risk. The study analysed the impact of climate hazards on over 200,000 hospitals globally and found that 71% of the hospitals at risk were in low- and middle-income countries. The report called for a rapid phase-out of fossil fuels to mitigate the risks to global health.
