We study optimal climate policy in a global economy where regions differ in wealth and climate vulnerability. Carbon emissions from production lead to output losses, and there is a technology for emissions absorption. We provide an aggregation result: the model with heterogeneity can be cast...

Carbon capture and storage (CCS) seems an appealing option to meet the ambitious objectives of the Paris Agreement. Captured CO2 emissions can also be injected in active fields to enhance recovery: Carbon capture and utilization (CCU). We study a dynamic model of CCS and CCU of an economy...

We model the value chain of Carbon Capture, transport and Storage (CCS) by focusing on the decisions taking by actors involved in either capture, transport or storage of CO2. Plants emitting CO2 are located along a Salop circle. If these invest in carbon capture facilities, the captured CO2 is...
