Contribution in Reducing CO2 Emissions Through Production Activities

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.

  • *1ITAKONA is a term unique to Panasonic which refers to a process by which we review stages prior to production to study raw materials to ensure waste is minimized and quality is maintained. We apply a similar review process for our CO2 emissions reduction efforts and call these our CO2 ITAKONA initiatives. The activity is aimed at discovering energy conservation measures from a new viewpoint through continuous display of energy consumption levels (energy consumption per basic unit), and analyzing the factors that influence the variables in each basic unit.

CO2 Emissions in Production Activities and the Trend of CO2 Emissions Per Basic Unit

  • *2Calculated with the weighted average of the improvement rate for CO2 emissions per basic unit of nominal production for each factory. The amount of CO2 emitted from each factory was used for weighting cases that had no improvements.
  • *3Increase in CO2 emissions per basic unit in fiscal 2012 and 2013 is due to the decline in production volume.
  • *4The factors related to fuels are based on the Guidelines for Calculation of Greenhouse Gas Emissions (version 2.2) published by the Japanese Ministry of the Environment. The CO2 emission factor for electricity purchased in Japan (kg-CO2/kWh) is fixed at 0.410. If the factors set for each fiscal year are used instead (0.425 for fiscal 2006, 0.351 for fiscal 2010, 0.350 for fiscal 2011, and 0.476 for fiscal 2012 and 2013), total CO2 emissions will be 4.63 million tons for fiscal 2006, 3.70 million tons for fiscal 2010, 3.74 million tons for fiscal 2011, 3.81 million tons for fiscal 2012, and 3.33 million tons for fiscal 2013. The factors above are also used for electricity purchased from power producers and suppliers (PPS). The GHG Protocol factors for each country are used for electricity purchased outside Japan.

Promotion of CO2 ITAKONA Initiative

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.

Concept of the CO2 ITAKONA Initiative

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.

  • *7METAGEJI is a term unique to Panasonic which refers to visualizing energy consumption and implementing measurable reduction initiatives by introducing measurement instruments, such as meters and gauges.

Promotion of Top Runner Factories for Saving and Creating Energy

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.

Sharing CO2 Reduction Examples and Training Experts

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.

Reducing the Emissions of GHGs Other Than CO2 From Energy Use

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.

CO2 Emission Reduction at Non-manufacturing Sites

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.

Initiatives for Green IT

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.
