Carbon trade-offs: how firms respond to emission controls
Regulation to control carbon emissions challenges firms to develop optimal carbon management policies. We set out a unified approach to study the trade-offs carbon pricing poses for firms and how they should therefore best respond. Our model shows that while carbon pricing curtails firms’ carbon emissions, polluting firms tilt their green investment mix towards more immediate yet short-lived options – such as solely reducing emissions (abatement) instead of investing in green innovation – as it becomes costlier to comply.
