5. Tokyo’s Leading Policies & Programs on Energy 5. Tokyo’s Leading Policies & Programs on Energy Conservation /CO 2 Emission Reductions (1/3) Conservation /CO 2 Emission Reductions (1/3) Primary Program 1 Primary Program 1 TMG Green Building Program (Enacted in 2000, started in 2002) TMG Green Building Program (Enacted in 2000, started in 2002) A program of environmental performance evaluation and public release of A program of environmental performance evaluation and public release of evaluation results of new buildings ( ＞ 5,000m 2 total floor area) evaluation results of new buildings ( ＞ 5,000m 2 total floor area) This system developed, reaching fruition with the labeling This system developed, reaching fruition with the labeling system system * Condominium environmental performance display system * Condominium environmental performance display system (enacted 2005) (enacted 2005) * Business building energy saving performance evaluation document * Business building energy saving performance evaluation document system (enacted 2010) system (enacted 2010) Various measures, such as (1) increasing energy saving standards, and Various measures, such as (1) increasing energy saving standards, and (2) demanding high energy performance through comprehensive design (2) demanding high energy performance through comprehensive design systems, etc., were launched utilizing this system systems, etc., were launched utilizing this system 6 Shuzo Murakami, Building Research Institute

6. Tokyo’s Leading Policies & Programs on Energy 6. Tokyo’s Leading Policies & Programs on Energy Conservation /CO2 Emission Reductions (2/3) Conservation /CO2 Emission Reductions (2/3) Primary Program 2 Primary Program 2 Tokyo Cap and Trade Program (Enacted in 2008, started in 2010) Tokyo Cap and Trade Program (Enacted in 2008, started in 2010) World’s first cap and trade system targeting at CO 2 emissions World’s first cap and trade system targeting at CO 2 emissions from buildings from buildings This program: This program: * Total emission reductions mandated for most of the large * Total emission reductions mandated for most of the large buildings in Tokyo, accelerating energy savings and buildings in Tokyo, accelerating energy savings and renewable energy use renewable energy use * Trading system resulted in wide-reaching effects * Trading system resulted in wide-reaching effects throughout Japan, such as the development of renewable throughout Japan, such as the development of renewable energy projects energy projects 7 Shuzo Murakami, Building Research Institute

7. Tokyo’s Leading Policies & Programs on Energy 7. Tokyo’s Leading Policies & Programs on Energy Conservation /CO2 Emission Reductions (3/3) Conservation /CO2 Emission Reductions (3/3) Example 1: Example 1: Tokyo Low Carbon Building TOP30 Tokyo Low Carbon Building TOP30 * Select and publish TOP 30 low emission buildings in Tokyo * Select and publish TOP 30 low emission buildings in Tokyo as a result of these two primary measures as a result of these two primary measures * Effect of widely publicizing the leading technologies of low * Effect of widely publicizing the leading technologies of low emission buildings, and the hard work of the architects and emission buildings, and the hard work of the architects and engineers behind them engineers behind them Example 2: Example 2: Leading measures by TMG have a large impact in energy Leading measures by TMG have a large impact in energy conservation policies of local and national governments conservation policies of local and national governments Has also been positively evaluated as an excellent example of Has also been positively evaluated as an excellent example of demand-side measures by cities worldwide demand-side measures by cities worldwide 8 Shuzo Murakami, Building Research Institute
