At COP28, CCS & CDR techs discussed to abate carbon emissions. CCS captures CO₂ from sources like fossil fuel industry & CDR uses natural means & techs like direct air capture. AR6 relies on CDR to limit warming to 1.5°C. CCS & CDR create room to emit, but use of coal, oil & gas must decline 95%, 60% & 45% by 2050. Concerns over land use & who pays for CDR at scale remain.
