A tax on carbon emissions is widely perceived (by economists) as the most efficient way to reduce carbon emissions and mitigate the costs of climate change. We will briefly review the structure of integrated assessment models of climate and the economy, and show how these models determine a socially optimal climate policy (emission reduction path) and the social cost of carbon. Application of the framework to guide research into the capacity of the oceans to absorb carbon will be described.
The shipping industry accounts for approximately 3% of global carbon emissions, roughly equivalent to the carbon emissions by Germany. The International Maritime Organization (IMO) has set a goal of at least a 50% reduction in carbon emissions from shipping by 2050 and a complete decarbonization as soon as possible thereafter. A “carbon levy” on bunker fuel could contribute to that goal and the concept has recently been endorsed by influential owners, charterers, and banks. The proposals will be reviewed along with the considerations (including speed reduction) motivating the specific recommendations.
