Modelling the competition for land: Methods and application to climate policy

WithRONALD SANDS AND MAN-KEUN KIM

Energy-economy models used for analysis of climate policy are under continuous development to expand the range of options for reducing net emissions of greenhouse gases. The classes of mitigation options under consideration include improvements in energy efficiency, switching to less carbon-intensive fuels, carbon dioxide capture and storage, reductions in emissions of non-CO2 greenhouse gases, and terrestrial mitigation options. The terrestrial options can be further broken down into afforestation, changes in forest management, production of biofuels, and enhancement of soil carbon. Therefore, we aremoving toward topdown models with agriculture-energy-economy capabilities. Adding a capability for terrestrial mitigation options to existing energy-economy models presents challenges in both conceptual development and data requirements.
