Environment:CO2 Reduction

Size of Contribution in Reducing CO2 Emissions

One of the long-term environmental targets set by the international community is to reduce emissions of CO2 and other GHGs by 50% from the 2005 level by the year 2050. To achieve this, CO2 emissions should "peak out" (reach a peak and decline thereafter) during the period from 2020 to 2030. With this background, companies are asked to contribute to reducing CO2 more than ever.

Panasonic has introduced a unique indicator "size of contribution in reducing CO2 emissions" to accelerate emissions reduction, targeting both our products (for energy saving and energy creation) and production activities. The size of contribution in reducing CO2 emissions is defined as the amount achieved by deducting the actual emissions from the amount that would have been emitted without improvements such as the energy-saving performance of our products and productivity from fiscal 2006. In other words, it reflects the continuous efforts being made to reduce CO2 emissions. Panasonic will continue to maximize the size of contribution in reducing CO2 emissions.

We will improve the energy-saving performance of our products to reduce the energy consumed in using the products. The more energy-saving products are introduced and promoted, the size of contribution in reducing CO2 emission will further increase.

Size of Contribution in Reducing CO2 Emissions Through Energy-saving Products

  • *1For each product category, the model that was sold in the largest quantity in the region was selected.
  • *2Regional CO2 emission factors (kg-CO2/kWh) used: 0.410 (Japan); 0.487 (Europe); 0.579 (North America); 0.740 (China); 0.927 (India); 0.527 (Asia Pacific, Northeast Asia); 0.332 (Latin America); 0.327 (other regions).
  • *3Number of years during which spare parts for the product are available (defined by Panasonic).

By using electricity generated by solar power generation and such, we can reduce CO2 emissions from thermal power plants. Panasonic will further foster its energy creation business to make an even greater contribution to CO2 emissions reduction.

Size of Contribution in Reducing CO2 Emissions Through Energy-creating Products

  • *4For photovoltaic power generation: 1,193 kWh/kW (considering sunshine conditions, system loss, and other variables).
  • *5For photovoltaic power generation: 0.3145 kg-CO2/kWh (considering energy used in the manufacturing process; by the Japan Photovoltaic Energy Association).
  • *6For photovoltaic power generation: 20 years.

The smaller amount of CO2 emissions per unit of production (tons/100 million yen),*7 the more efficient productivity is, and the size of contribution in reducing CO2 emissions in production activities will increase.

  • *7Productivity indicator (Energy consumed in manufacturing products whose total monetary value is 100 million yen, converted to the amount of CO2 emissions).

Size of Contribution in Reducing CO2 Emissions Through Production Activities

  • *8Factories whose nominal energy consumption per basic unit of production had increased from the fiscal 2006 level due to sharp declines in product prices recorded negative figures in the size of contribution in reducing CO2 emissions. For the size of contribution made by factories consolidated or sold in fiscal 2007 onwards, CO2 emissions in fiscal 2006 were used for the calculation. For factories purchased, CO2 emissions in fiscal 2006 were not deemed as a negative contribution.
  • *9CO2 emissions per basic unit for fiscal 2006 were used for factories acquired; while for factories newly constructed, the CO2 emissions per basic unit for the fiscal year in which they were constructed were used.
  • *10The factors related to fuels are based on the Guideline 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. The factors above are also used for electricity purchased from power producers and suppliers (PPS). The GHG Protocol’s factors for each country are used for electricity purchased outside Japan.
  • *11Nominal production value.

Relative to the target of 41 million tons in fiscal 2013, the size of contribution in reducing CO2 emissions came to 39.7 million tons, mainly due to the drop in sales of consumer goods.
