This study presents the results of the most recently completed international collaboration under Stanford University's Energy Modeling Forum that provides a comprehensive report on a comparative set of analyses of the economic and energy sector impacts of multi-gas mitigation of anthropogenic greenhouse gases.

The objectives of EMF 21 study were to conduct a new comprehensive , multi-gas policy assessment to improve the understanding of the affects of including non-CO2 GHGs (NCGGs) and landuse (terrestrial sequestration) into short- andlong-term mitigation policies. EMf 21 essentially answers the following question: How important are NCGGs & landuse in climate policies?

It provided explanations for differences in results from different models and identified high priority areas for future research and advanced the state-of-the-art in integrated assessment and climate economic modeling.  In addition, it strengthened collaboration between NCGG and landuse experts and modeling teams.

All papers are part of a Special Issue of The Energy Journal, November 2006. The volume can be cited as: F. de la Chesnaye and J. Weyant and (eds). Multi-Greenhouse Gas Mitigation and Climate Policy.
