I don't understand your opposition to the idea of individuals contributing to carbon offset projects. It seems like the reservations you've expressed (it's not a whole solution, it's not feasible for people earning less than $2 per day, it might have too much of a "feel good" effect, etc) are equally true of many ideas you'd probably like, including the ideas you put forward yourself.

I liked this part of your comment: "RUN THE NUMBERS please". I did. Illuminating! My back-of-napkin:

  Global CO2 emissions were 10b tons (10 Gigatonnes) in 2014 (https://www.co2.earth/global-co2-emissions)

  $4.5B per month * 12mo = ~$50 billion per year

  Carbon offset costs vary wildly. That's the big Q. You will have to do your own research on this, but to me, $100 per ton seems conservative, and $10 seems very generous.

  If Wren collects $5B per month, and offsets cost $100 per ton, they would offset 5% of 2014-level annual emissions. (Probably less than our annual increase.) 

  If offsets cost $10 per ton, it's 50% -- more meaningful!
