The most important component of a strategy to reduce CO2 emissions is a carbon tax, which is economically equivalent to a cap-and-trade system. However, people involved in tech seem to be especially prone to what I call a "problem solving" bias: discrete problems require discrete solutions, and we just have to figure out if the right solution is solar, nuclear, or the Savory Institute. The (correct) economic point of view is that there are many possible solutions, and a carbon tax properly incentivizes implementing all of them.

On the issue of China, because their per capita emissions are so low, and any reasonable global cap and trade system would allocate CO2 emissions rights to countries on a per-capita basis (or at least per-capita indexed to some base year like 1960), China is not actually the bad guy, and under a fair cap and trade system they would be net sellers of CO2 credits not the other way around. However too many people are blinkered by anti-Sinitism to accept this fact.
