Medium- to Long-Term Environmental Conservation Targets and Results

The influence of climate change, such as extreme weather events, has been gradually worsening, and the world's movement toward the reduction of greenhouse gas has been increasingly activated. Global environmental issues are posing a significant threat to "ensuring food security", as well as "ensuring a safe and secure water supply."

In order to contribute to building a sustainable society as a sustainable company, the Kubota Group has been promoting environmental activities by formulating its medium and long-term targets for environmental conservation. The Kubota Group has formulated Long-Term Environmental Conservation Targets for 2030 and Medium-Term Environmental Targets for 2020. Toward achieving these targets, the Group is advancing systematic initiatives in both the production and product development stages.

Long-Term Environmental Conservation Targets 2030

Efforts to stop climate change

Reduce CO2 emissions from the Kubota Group in Japan*1 by 30% compared to the base year 2014

Efforts to develop environment-conscious products

Increase the sales ratio of Eco-Products*2 certified products to 80%
Aim to put all new products which are certified as Eco-Products on the market in 2030 and later

Medium-Term Environmental Conservation Targets 2020 and the Results for RY2016

In RY2016, the Kubota Group started the initiatives toward achieving its new medium-term targets, Medium-term Environmental Conservation Targets 2020. Each business site and division determined measures to take and formulated an implementation plan up to RY2020, taking into consideration the fluctuations in the volume and contents of business. From now on, we will work to ensure the implementation of the plans and examine advanced measures.

Develop vehicles compliant with exhaust gas regulations Development of industrial diesel engines that comply with the latest emission regulations of Japan, the US and Europe and putting on the market of the engine-based products*8 The following products*10 were put on the market.

・Tractors(M6S Series):
North America EPA Regulation (75 kW and above, lower than 130 kW, Tier 4)

・Tractor(WORLD M1060W):
Japan regulations on Emissions from Non-Road Special Motor Vehicles (75 kW and above, lower than 130 kW, Regulation 2014)

*1 CO2 emissions include greenhouse gases from non-energy sources. In Medium-Term Environmental Conservation Targets 2020, we use the emissions coefficient for electricity of the base year in our calculation of CO2 emissions from energy sources.

*2 The sales ratio of the products which have fulfilled the internal requirements in our own Eco-Products Certification System
Sales ratio of Eco-Products (%) = Sales of Eco-Products / Sales of products (excluding construction work, services, software, parts and accessories) × 100

*3 VOCs (volatile organic compounds) comprise the six substances that are most prevalent in emissions from the Kubota Group: xylene, toluene, ethylbenzene, styrene, 1, 2, 4-trimethylbenzene, and 1, 3, 5-trimethylbenzene.

*4 The figures per unit of production represent the intensity of the environmental load per unit of production money amount. The exchange rate of the base year is used when translating the production money amount of overseas sites into Japanese yen.

*5 Recycling ratio (%) = (Sales amount of valuable resources + External recycling amount) / (Sales amount of valuable resources + External recycling amount + Landfill disposal) × 100.
Heat recovery is included in external recycling amount.

*6 VOC emissions and the production money amount of Great Plains Manufacturing, Inc. (GP), which became Kubota's consolidated subsidiary in July 2016, are excluded from the calculation of the VOC emissions per unit of production for the result of RY2016.

*7 Usage ratio of recycled materials (%):materials used in the cast metal products and parts (ductile iron pipes, fittings, machine cast products (engine crankcase, etc.))

*8 Targeting the tractors and combine harvesters (output range: 56 kW≤P<560 kW) equipped with engines compliant with the European emissions regulations (Europe Stage IV) level, shipped to Europe, North America, Japan, and Korea.

*9 ▲ means "minus".

As an "Eco-First Company"

In May 2010, the Kubota Group was certified by the Japan's Ministry for Environment as an "Eco-First Company" due to its commitments to environmental conservation. In 2016, the Group submitted an application to renew its Eco-Fast commitments based on the new medium and long-term targets.
