Shale growth has been slowing due to fears over the energy transition, as Permian upstream CO2 emissions reached a new high in 2019. We disaggregate the CO2 across 14 causes. It could be eliminated by improved technologies, making Permian production carbon neutral: uplifting NPVs by c$4-7/boe, re-attracting a vast wave of capital and growth. This note identifies the best opportunities.
