Size of Contribution in Reducing CO2 Emissions

The Paris Agreement that went into effect in November 2016 sets out a target to limit global temperature increases to less than 2°C above pre-industrial levels and a more ambitious target to keep global temperature increases to less than 1.5°C above pre-industrial levels, as well as sets the goal for CO2 and other greenhouse gas emission levels for the second half of this century to be virtually zero. To achieve these targets, it is essential to cut CO2 emissions to the greatest extent possible, and companies are required to make further contributions to reducing CO2 emissions.

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 the improvements by the energy-saving performance of our products and productivity from fiscal 2006, and this amount is combined with the emission reduction resulting from power generation by energy-creating products. 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 emissions will further increase.

The amount achieved by deducting the actual emissions from the amount that would have been emitted without the improvements by the energy-saving performance of our products from fiscal 2006,

*1 For each product category, the model that was sold in the largest quantity in the region was selected.
*2 Regional CO2 emission factors (kg-CO2/kWh) used: 0.410 (Japan); 0.487 (Europe); 0.579 (North America); 0.740 (China & Northeast Asia); 0.927 (India & South Asia); 0.527 (Southeast Asia & Oceania); 0.332 (Latin America); and 0.599 (Middle East & Africa).
*3 Number 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 increase the size of contribution in reducing CO2 emissions.

The emission reduction resulting from power generation by energy-creating products

*4 For photovoltaic power generation: 1,204 kWh/kW (after fiscal 2015), 1,193 kWh/kW (fiscal 2014 and prior).Considering sunshine conditions, system loss, and other variables.
*5 For photovoltaic power generation: 0.360kg-CO2/kWh (Source: Voluntary Rules on Indication (2010) by the Japan Photovoltaic Energy Association).
*6 For photovoltaic power generation: 20 years.

Meanwhile, since fiscal 2014, Panasonic has been reinforcing its housing, automotive, and B2B businesses, and is disclosing the CO2 reduction effect results in these areas from fiscal 2015. Specifically, the data represents “air conditioning load reduction effects from improved insulation performance in Panasonic housing,” “energy-saving effects from products by other companies equipped with Panasonic energy-saving compressors and motors,” and “improved fuel economy effects from electric vehicles equipped with Panasonic automotive batteries.” Starting with the results for fiscal 2016, the energy-saving effect of products by other manufacturers using Panasonic vacuum insulation materials is calculated and disclosed. From the results for fiscal 2017, CO2 reduction effects as a result of energy saving such as less travelling made possible through the use of HD Visual Communication Systems are also calculated and disclosed.

We regard such contribution in reducing CO2 emissions as “indirect” contribution to reducing CO2 emissions, to distinguish them from the direct contribution from products under the Panasonic brand such as home appliances. This indicates that Panasonic products support the CO2 reduction effects for products by other manufacturers.

Our size contribution in reducing CO2 emissions through products and services amounted to 52.69 million tons in fiscal 2017. Of this, direct contributions amounted to 39.58 million tons, and indirect contributions to 13.11 million tons.

*8 Size of contribution in reducing CO2 emissions in the housing, automotive, and B2B businesses. Started calculating from fiscal 2015.
*9 From fiscal 2017, the size of contribution in reducing CO2 emissions for household air conditioners are calculated based on the updated standards (e.g. JIS) employed in calculating the annual power consumption. The amount of the size of direct contribution in reducing CO2 emissions based on the previous calculation method is 42.03 million tons.

Following the conclusion of the Paris Agreement in 2015, the world reached an agreement to limit temperature rises to 2°C above pre-industrial levels. The following findings have been reported in recent studies.

  • The 2°C limit cannot be achieved unless dramatic cuts are made to CO2 emissions immediately.
  • It is possible to keep to the 2°C limit if reductions in greenhouse gas emissions are started in 2015, but a 5-year delay in commencement is expected to cause the temperature to rise by 2.5°C. A 10-year delay is predicted to cause the temperature to rise by over 3°C, far exceeding the 2°C limit.
  • Even if emission reductions were implemented right away, actual reductions must be achieved at a great speed that would accomplish carbon positive by 2080.

It is imperative to reduce as must as possible the amount of energy consumed during the use of electrical appliances designed to be used for a long period. This is all the more essential in view of the fact that we cannot rely on nuclear power. Panasonic has supplied energy-saving products and energy-creating products to the market at an early stage, thereby contributing to reducing CO2 emissions in the entire society. Panasonic's size of contribution in reducing CO2 emissions in fiscal 2017 was 52.69 million tons, which is equivalent to roughly 4% of the total amount of emissions in Japan—this is a significantly major effect. The steady increase in the size of contribution since fiscal 2011 demonstrates the company's continuing efforts for innovation in its environmental activities.

Panasonic's efforts to mitigate climate change are indeed diverse, covering not only its end-products but also its supply of intermediate products and business solutions with high energy efficiency. In addition, its active implementation of measures to adapt to climate change, including the 100,000 Solar Lanterns Project and the Coastal Monitoring System, is worth recognition. I look forward to Panasonic's continued execution of powerful initiatives as a leading global company working to address climate change from all directions.
