[en] Carbon capture and storage ; differential game
[en] Carbon capture and storage (CCS) is considered one of the most important and efficient
tools in fighting against greenhouse gas emissions. Countries differ in terms of the level
CCS processes implemented, with the main barrier to CCS adoption being its high
cost. This paper introduces a differential game model with heterogeneous countries
to investigate the optimal timing for countries to initiate CCS projects, taking into
account CCS costs. We show that (i) the thresholds for the triggering of CCS projects
depend not only on one's own CCS costs but also those of others, in addition to the
pollution damage costs; (ii) the optimal timing for different countries to initiate their
CCS projects is the moment when their threshold level of pollution stock is reached;
(iii) countries are more inclined to free-ride by both reducing pollutant emissions and
deploying CCS when pollution damage costs are symmetric rather than asymmetric;
finally, (iv) we provide sufficient conditions under which some countries never deploy
CCS even though they bear the same pollution damage as the others.
