Initiatives at Operational Sites

CO2 Reduction Through Initiatives at Operational Sites

Canon strives to improve energy efficiency at operational sites in order to restrict the volume of CO2 emissions during operation.

Initiatives to Improve Energy Efficiency at Operational Sites

Canon’s development, manufacturing, and facilities and environment divisions are working together to improve energy efficiency and lower the company’s CO2 emissions.

In particular, we are strengthening cooperation with products operations to eliminate wastage and optimize production processes and facility operation while maintaining the required quality of products and parts.

For example, in the manufacture of fluoride crystals by Canon Optron Inc., we improved production efficiency and reduced energy consumption by making improvements to the manufacturing process and to equipment, allowing an increased number of layers to be produced per batch.

We are also continually working to optimize facilities operations. We optimized refrigeration at our Ayase site and temperature and humidity management in the production area of Taiwan Canon, allowing more efficient use of energy.

We are constantly expanding energy-saving initiatives that prove effective at one site to other sites within the Canon Group.

In addition, we are promoting green building initiatives at our sales offices. Canon Canada’s new head office has improved energy efficiency thanks to the use of highly energy-efficient devices such as lighting and blinds that adjust automatically depending on the amount of external light.

As a result, total greenhouse gas emissions in 2016 were 1,118,721 tons, down approximately 3.9% compared to 2015.

  • * Canon’s calculation of total greenhouse gas emissions
    Calculation of energy-derived greenhouse gas CO2, and the non-energy derived greenhouse gases, PFCs, HFCs, SF6, N2O, methane, and NF3. Through 2014, conversion to CO2 is made using annual coefficients for each region. Coefficients supplied by Japan’s Ministry of the Environment and the Federation of Electric Power Companies of Japan are used for site activities in Japan, and coefficients supplied by the International Energy Agency (IEA) are used for site activities in regions outside Japan. From 2015, CO2 conversion coefficients from the Electric Power Council for a Low Carbon Society are used, and where coefficients are not provided by electric power companies, publicly provided coefficients by region are used. As there is a delay between compilation and disclosure of data, CO2 conversion coefficients are adjusted retroactively.
  • Note: Sales outlets (worldwide) of marketing companies included in
    data count have been expanded starting in 2013.

Contributing to Increased Use of Renewable Energy

Use of Renewable Energy Suited to Regional Characteristics

To increase the use of renewable energy, which is a SDG target, preparation of infrastructure suited to regional characteristics is under way.

Canon aims through the end of 2020 to derive from renewable sources at least 130MWh of the energy it uses at sites in Japan, and at least 85,000MWh of the energy it uses at sites outside Japan.

We are currently working to expand the use of renewable energy, especially in Europe, while keeping regional renewable energy uptake status and economic feasibility under consideration. For example, three main sites of Axis Communications AB (Sweden) and three group companies of Océ purchase nearly 100% of their energy from renewable sources.

Océ employs a geothermal HVAC system that uses the temperature difference of groundwater as an energy source for a heating and cooling system.

Use of Renewable Energy by Region in 2016 (MWh)
Japan 124
North American region 9,209
European region 73,544
Asia and Oceania region (excluding Japan) 495
