Canon strives to improve energy efficiency at operational sites in order to restrict the volume of CO2 emissions during operation.
In 2017, while the addition of Canon Medical Systems to the Canon Group increased GHG emissions, the level of emissions from existing operations was lower in year-on-year terms due to concerted energy-saving measures across operational sites.
As a result, total emissions in 2017 of 1,162 kt-CO2 were only slightly higher than in 2016, and our emissions per unit of sales improved to 28.48 t-CO2/100 million Yen.
Since 2014, Canon has created the Energy Cost Reduction Working Group and has been working mainly with production divisions on initiatives to cut energy costs.
In 2015, Canon formed the Energy Efficiency Diagnosis Team to coordinate improvements in the operational efficiency of equipment based on regular audits of equipment status and operating settings. Training sessions were also organized for production personnel aimed at making further improvements with limited investment.
These activities have been extended to Canon Group companies worldwide, including development divisions and all production sites outside Japan. More than 3,000 measures to improve energy efficiency were implemented in the three-year period of 2014-2016, generating overall energy savings of approximately 40,000kl (crude oil equivalent), or roughly 3% of total annual energy consumption.
Canon received the Agency of Natural Resources and Energy Director-General Award at the Energy Conservation Grand Prize 2017 in Japan.
To increase the use of renewable energy, which is a SDGs' target, preparation of infrastructure suited regional characteristics is under way. Canon aims through the end of 2020 to derive from renewable sources at least 300MWh of energy it uses at sites in Japan, and at least 85,000MWh of energy it uses at sites outside Japan.
Total renewable energy consumption by Canon Group companies worldwide in 2017 was 88,984 MWh, an increase of about 7% compared with 2016.
Canon is currently working to expand the use of renewable energy, especially in Europe, while keeping regional renewable energy uptake status and economic feasibility under consideration.
Océ Technologies, a Canon Group company, employs geothermal energy storage systems that uses the temperature differential with groundwater to power heating and cooling systems. Compared with conventional systems that are powered by electricity or natural gas, this results in lowering CO2 emissions. The company also buys nearly all its power from renewable sources such as wind.
In order to reduce CO2 emissions from product distribution, Canon has undertaken several initiatives: modal shifts that utilize transport modes with a lower environmental impact, improving loading efficiency by downsizing of products and packaging, diversion or direct-shipment from production sites, and shortening routes by consolidating distribution centers. In addition to these initiatives, to further improve transport efficiency, instead of the traditional one-way transport of containers with cargo, we have been actively pursuing Container Round Use (CRU), which includes not just containers within the Canon Group, but also containers imported by other companies for us to export. We are working with carriers and container transporters to expand the initiative in regions. We are also expanding the initiative to our overseas sites, and have introduced it in China, Vietnam, Thailand, the Philippines, and Malaysia.
In 2017, CO2 emissions from logistics operations amounted to 291 kilotons, a decrease of one kiloton compared to 2016.
