With respect to our CO2 targets, we achieved 0.84 million tons in CO2 emissions reductions in our production activities by fiscal 2010, far exceeding our target of 0.3 million tons from fiscal 2007. By pursuing continuous improvement of our energy management capabilities and lowering our CO2 emissions per basic unit, we aimed to maximize our contribution in reducing CO2 emissions in production activities from fiscal 2011.
We promoted measures including CO2 ITAKONA*1 initiatives, Top Runner Factories for saving and creating energy, sharing CO2 reduction examples and training experts through the entire Group, and as a result, we increased the size of contribution in reducing CO2 emissions through production activities in fiscal 2013 to 2.75 million tons, exceeding our target of 2.55 million tons.
To ensure the reduction of CO2 emissions at our factories, it is important to track the energy consumption of each factory and the effects of specific emissions reduction measures to visualize reduction effects. To date, we have introduced more than 40,000 measurement systems and Factory Energy Management Systems (FEMS) at all of our global manufacturing sites, and we have continued to promote our CO2 METAGEJI*7 initiative.
Based on this scheme, the CO2 ITAKONA initiative has been implemented since fiscal 2011. The activity is aimed at discovering energy conservation measures from a new viewpoint through continuous display of energy consumption per basic unit of production, and analyzing the factors that influence the variables in each basic unit.
In order to accelerate action under the CO2 ITAKONA initiative, we have been developing the SE-Navi software, which enables the simultaneous display of energy and production data and analysis of energy consumption per basic unit. In fiscal 2013, the “energy-saving navigation function” was developed as a new feature of the software.
In the past, energy consumption and other data had been analyzed manually by specialists in order to develop energy conserving measures. The new energy-saving navigation function has enabled automatic data analysis and measurement, based on an energy-saving measures database. This contributed not only to a reduction in work time but also to the identification of energy-saving measures without the assistance of specialists. This new function was introduced in Panasonic Corporation Eco Solutions Company's air conditioner manufacturing factory and contributed to CO2 emissions reduction of approx. 10% in fiscal 2013.
To further promote energy conservation and reduce CO2 emissions across our company, since fiscal 2011 we have selected Top Runner Factories in each of our business domains to provide a model for other factories in the domain to follow. Top Runner Factories make investments in energy conservation and create three-year implementation plans that are used to raise the environmental performance of all companies within the domain. This plan provides guidance in six areas: (1) Introducing top-level production process innovations, (2) Maintaining and managing highly efficient manufacturing equipment, (3) Pursuing the top-level rate of CO2 emissions reduction per basic unit, (4) Implementing system for energy consumption visualization, (5) Promoting factory-wide CO2 emissions reduction efforts in production processes, and (6) Introducing photovoltaic power generation system.
Selected Top Runner Factories are required to have outstanding and specialized features in energy conservation. Through this initiative, Top Runner Factories achieve the highest level of energy saving in the domain company, as well as develop No.1 energy-saving technologies for their specialized area. Such cases of advanced factories are rolled out across relating factories worldwide by Top Runner Factories.
A photovoltaic power generation system of 600 kW was introduced at the Kita-kadoma site in Osaka in July 2012. Further action into the introduction of recyclable energy will be implemented in the future, chiefly using solar power generation.
In September 2008, we created a keyword search system on the intranet with a database of CO2 reduction examples called BA Charts.*8 A total of 1,100 examples are registered in the database and we are now promoting its use across the company.
For the promotion of energy conservation initiatives, it is critical to train engineers versed in energy-saving technologies. Accordingly, Panasonic has held 45 training seminars on CO2 reduction since fiscal 2008, developing a total of 1,037 experts.
Not only studying theory, from fiscal 2011, we also began holding a competition on energy conservation diagnosis skills (ability to present proposals of improvement measures for energy conservation at offices and factories). These activities promote the development of human resources who have both theoretical and practical knowledge about onsite energy-saving activities.
In addition to CO2, Panasonic emits PFCs, SF6, and other GHGs, which are mainly used as etching and cleaning gases at its semiconductor factories. In order to reduce the emissions of these gases, our semiconductor factories have been implementing measures including substituting such gases with those having lower environmental impact and installing GHG removal devices to recover the generated gases and render them harmless.
The World Semiconductor Council has been continuing until 2012 its aim to reduce GHG emissions by at least 10% from the 1995 level by 2010. Panasonic's semiconductor department has achieved a 69% reduction from the 1995 level in fiscal 2013.
In our efforts to reduce CO2 emissions from our production activities, we have also focused on measures aimed at curtailing emissions at non-manufacturing sites, including offices and research centers, since fiscal 2009. We have set a company-wide target of reducing CO2 emissions by an average of 2% or more each year, over a baseline year of fiscal 2008, at 75 self-owned office buildings in Japan. To meet this goal, each site has implemented a three-year energy conservation plan while also taking steps to conduct energy conservation diagnoses to visualize the nature and amount of waste. As a result, we have reached our goal in fiscal 2013, reducing our CO2 emissions by approx. 0.18 million tons, marking an annual average reduction of about 4% compared with the fiscal 2008 baseline level.
From fiscal 2011, we started to check on a monthly basis the progress of all 120 sites including 45 sites owned by other companies. Furthermore, our original tool for energy conservation self-assessment, Green Office Assessment, is employed to inspect the status of activities in this area, based on 40 specific energy-saving items, in order to upgrade management levels.
Note: Scope of the data: Non-manufacturing sites with 100 or more employees. CO2 emission factor for electricity purchased: 0.410 kg CO2/kWh.
We promote Green IT in the drive to employ IT in cutting down environmental impacts. Specifically, PC power control and reduction of IT equipment standby power have been strengthened for energy conservation as well as operational improvement of IT equipment under the title Green of IT. Under the theme Green by IT, IT applications for energy reduction in society as a whole, such as teleworking, web conferencing, and HD video communications, are being promoted. The third area in energy conservation is the Green Data Center, which engages in data center energy reduction through server consolidation and integration.
