Description: This document is part of Technical Report (ref: EUR 21758 EN) from the Joint Research Centre and presents part of the modelling work conducted by DG JRC/IPTS as a contribution to the DG ENV Communication on post-2012 climate policy analysis (June 2005). The analyses with the POLES and GEM-E3 models show that the costs of abatement policies, both in marginal terms and total terms, can be significantly reduced if emissions trading and project based mechanisms are used.

Description: This study compiles and updates the findings of 16 comprehensive state climate action plans and extrapolates the results to the nation. The study then takes those results and using a widely accepted econometric model projects the national impact of these policies on employment, incomes, gross domestic product (GDP) and consumer energy prices. Finally, using the bottom-up data developed by the states and aggregated here, the study models the national impact of major features of the Kerry-Lieberman climate bill under consideration in Congress in 2010. These state action plans and supporting assessments were proposed by over 1,500 stakeholders and technical work group experts appointed by 16 governors and state legislatures to address climate, energy and economic needs through comprehensive, fact-based, consensus-driven, climate action planning processes conducted over the past five years with facilitative and technical assistance by the Center for Climate Strategies. Findings show potential national improvements from implementation of a top set of 23 major sector-based policies and measures drawn from state plans.
