Climate Change Countermeasures

The Chugai Group considers climate change to be an important issue for global environmental protection, and is working to reduce the volume of its GHG*1 emissions. As part of this effort, we are working to reduce energy consumption, promoting the introduction of fuel-efficient vehicles*2, and reducing the use of specified CFCs*3 toward our goal of discontinuing their use by 2020.
*1 GHG:Greenhouse Gas
*2 Includes hybrids and class 3 fuel-efficient vehicles
*3 Includes CFC: chlorofluorocarbons, HCFC: hydrochlorofluorocarbons

Reducing Energy Consumption

The Chugai Group in mid-term environmental goals set a target of reducing energy consumption by 20 percent compared with the 2010 level of 350 gigajoules (GJ) per employee.
While no numerical targets were set for energy consumption for 2015, efforts continued to reduce energy use. Progress in 2015 toward achieving our mid-term environmental goals included a 13% reduction in consumption compared with 2010, to 2,176 gigajoules. Note that total CO2 emissions were down by 414 tons, a 1.9% reduction compared to 2014.

Power-Saving Measures

The Chugai Group engages in power-saving measures year-round. Through our summer (June-September) “cool biz” and winter (January-March, December) “warm biz” campaigns, our head office, branches (tenant offices) and Chugai Distribution reduced power use by 4.6% over 2014, to 5,346 MWh. At research laboratories and plants (five major sites), fuel conversion reduced heavy oil use by about 1,806 kL, contributing to an increase of 4.6% over 2014, to 123,842 MWh. Company-wide, power use increased by 4.2%, to 129,188 MWh.

Discontinuation of Use of and Conversion from Halogenated Hydrocarbons

By 2020, the Chugai Group aims to eliminate equipment that uses chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), which have a high global-warming potential and deplete the ozone layer.
We are working to replace it with equipment that uses less ozone-depleting hydrocarbons. The total amount of CFCs and HCFCs used was 5,690 kg, a decrease of 56 kg from 2014. We are also closely monitoring the amount of hydrocarbons used to replenish the portion that leaked from equipment (the amount of CFCs and HCFCs refilled in 2015).

Introduction of Fuel-Efficient Sales Vehicles

Chugai began introducing hybrid vehicles to its MR fleet in 2003. We have been increasing the ratio of hybrid vehicles to reach the goal we set in 2006 of 50 percent of our MR fleet by the end of 2012. In 2014, we once again set a fuel efficiency goal of 16 km/L by 2020, and we continue working toward even greater efficiency.
At the end of 2015, we had a total of 1,023 hybrid vehicles and conventional vehicles with similar fuel efficiency, which accounts for 55 percent of our fleet.
