I am cross posting some comments here, that I made in my nascent CDR "microblog" on kbin - a channel that I am finding less effective in its current state of development.
"The past and ongoing emissions of CO2 are absolutely unjust, among their various other detractions. The tendency to continue business-as-usual is at odds with everything that we must now do. When I first became involved in environmentalism, the slogan was "think globally, act locally" and I have never ceased in that. There is injustice, and it will not end. But I will focus my efforts toward bring about the changes I want to see. Those changes prominently include achieving net-zero CO2 emission in my life (I could have another 30 years or so if I am lucky). It would be great if that happens because every coal mine, oil well, and natural gas well in the world were to be capped. But I suspect that is a bad gamble. As a hedge, and an optimistic effort to turn the balance toward actual NEGATIVE emission - I, having a low influence on the machinations of oil companies, try to understand the options for undoing some of what we've done - in ways that increase some of the social justice we have lost."
