Investigating Technology Options for Climate Policies: Differentiated Roles in ADAGE

This paper examines a range of technological and regulatory approaches to reducing greenhouse gas (GHG) emissions. Availability of new technologies will control how the economy and energy infrastructure respond to any future climate policies. How such policies interact with other types of environmental regulations will also influence the best options for meeting emissions goals. To investigate these effects, the ADAGE model is used to examine policy impacts for several climate and technology scenarios, focusing on key factors such as emissions, technology deployment, energy prices and macroeconomic indicators. In general, the simulations indicate that reductions in GHG emissions can be accomplished with limited economic adjustments, although the impacts depend on both the regulatory approaches used and the future availability of new low-carbon technologies.
