3. Challenges in reporting on R&D PAMs Several PAMs involve long-term research and development, such as: –New technologies for carbon sequestration –Development of hydrogen fuel cells Difficult to estimate effects of long-term PAMs in near term (e.g., 2010) Several PAMs involve long-term research and development, such as: –New technologies for carbon sequestration –Development of hydrogen fuel cells Difficult to estimate effects of long-term PAMs in near term (e.g., 2010)

4. Relationship of PAMs to Projections Effects of PAMs estimated using bottom-up analyses Aggregate emissions projections genererated using top-down national model Not possible to cross-walk effects of individual PAMs with national projections Effects of PAMs estimated using bottom-up analyses Aggregate emissions projections genererated using top-down national model Not possible to cross-walk effects of individual PAMs with national projections

5. Reporting at different levels Reported on PAMs undertaken by federal, state, and local governments, as well as NGOs and private sector Presented estimates of effects comprehensively for federal activities Estimates of effects for selected state, local, and private activities - illustrative, not comprehensive Reported on PAMs undertaken by federal, state, and local governments, as well as NGOs and private sector Presented estimates of effects comprehensively for federal activities Estimates of effects for selected state, local, and private activities - illustrative, not comprehensive
