Our raison d’être
We have to reduce excess atmospheric CO2 on a massive scale
It is not enough to reduce/stop new emissions
The sheer scale needed imposes important constraints
The space needed to store the CO2 is immense; It cannot be transported far etc.
There must be value creation, not only cost
If it's just about cost, then it's at the whim of government policies
Value creation must occur independently of what others do
To avoid “tragedy of the commons” effects
