This is a fantastic mapping and prioritization of climate emissions, and how mature technologies on each case to engineer out the "green premium" so we can "get to zero" (net emissions). It also makes connections to several fields. Worth noting that it leaves as secondary "nature based solutions", non-climate benefits or non-tech interventions. E.g. the value and benefits of ecological diversity by strengthening forests beyond their carbon stock potential, or policy-only interventions. If you want a complementary view, I recommend "the nature of nature" by Enric Sala.
