Medium- to Long-Term Environmental Conservation Targets

 The influence of climate change, such as extreme weather events, has been gradually worsening, and the global movement toward the reduction of greenhouse gas has become increasingly active. Global environmental issues pose a significant threat to “ensuring food security,” as well as “ensuring a safe and secure water supply.”
 In order to promote environmental management and contribute to the resolution of various issues, such as SDGs, 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 2030 and Medium-Term Environmental Conservation Targets 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

1. Efforts to Stop Climate Change

Goal Reduce CO2 emissions from the Kubota Group in Japan*1 by 30% compared to the base year 2014
Result In 2017, CO2 emissions of the Kubota Group in Japan*1 were reduced by 16.3% compared to the base year 2014.
Trends in the CO2 Emissions of the Kubota Group in Japan*2
  • CO2 emissions include greenhouse gases from non-energy sources.
  • Values for RY2016 were corrected to improve accuracy.


2. Efforts to Develop Environment-friendly Products

Goal Increase the sales ratio of Eco-Products-certified products*1 to 80% by 2030.
Aim to put all new products which are certified as Eco-Products in the market in 2030 and later.
Result The sales ratio of Eco-Product-certified products*1 was 55.6% in RY2017.
Trends in Sales Ratio of Eco-Product-certified Products
  • The sales ratio of products that 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
  

Medium-Term Environmental Conservation Targets 2020

 Since 2016, the Kubota Group has been advancing initiatives toward achieving the Medium-Term Environmental Conservation Targets 2020. Each business site and division determined the measures to take, formulated an implementation plan, taking into consideration fluctuations in the volume and contents of business, and has been implementing the plan. The results for RY2017 are as shown in the table below. For global production sites, the targets for RY2020 for all items were achieved earlier than planned. For the product segment, 34 products were newly certified as Eco-Products, boosting their ratio to sales by 11.4 point from the previous year to 55.6%.

Tackling Climate Change Reduce CO2*1 CO2emissions per unit of production 2014 -14% -15.2% We are promoting the energy-saving initiatives for production equipment, lighting, etc., fuel conversion, and the measures for heat insulation of buildings.
Save energy Energy consumption per unit of production 2014 -10% -13.0%
Working towards a Recyclingbased Society Reduce waste Waste discharge per unit of production 2014 -10% -13.6% We are promoting thorough sorting of wastes and converting waste into valuable resources.
Recycling ratio (Japan)*4 - Maintain 99.5% or more 99.8% We are maintaining the existing level through continuous efforts.
Recycling ratio (Overseas)*4 - Maintain 90.0% or more 91.4% We are promoting the reduction of the amount of waste sent to landfills by changing contractors.
Conserving Water Resources Conserve water resources Water consumption per unit of production 2014 -10% -16.9% We are promoting recycling of wastewater and saving of water use.
Controlling Chemical Substances Reduce VOCs*2 VOC emissions per unit of production*6 2014 -10% -25.1% We are promoting the elimination or reduction of VOC-contained paint, thinner.
Product Improving Product's Environmental Performance Expand Eco-Products Sales ratio of Eco-Products*5 - 60% or more  55.6% In RY2017, 34 products were newly certified as Eco- Products.
Promote recycling Usage ratio of recycled materials*6 - Maintain 70% or more More than 70% We are maintaining the usage ratio of recycled materials higher than the target.
Develop vehicles compliant with exhaust gas regulations Development of industrial diesel engines that comply with the latest emissions regulations, and launch onto the market of products with such engines*7 The following products*8 equipped with the engines that comply with the emissions regulations were launched onto the market.
・Tractors (GENEST Series):
 Conforming to the Japan Regulations on Emissions from Non-Road Special Motor Vehicles (75 kW and above, lower than 130 kW, Regulation 2014)
・Combine harvesters (Korea Special ER595K):
 Conforming to the Korean Agricultural Machinery Regulations Tier 4 (56 kW and above, lower than 130 kW)
  • CO2 emissions include greenhouse gases from non-energy sources. We use the emissions coefficient for electric power of the base year in our calculation of CO2 emissions from energy sources.
  • 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.
  • The figures per unit of production represent the intensity of the environmental load per unit of money amount of production. The exchange rate of the base year is used when translating the money amount of production of overseas sites into Japanese yen. The figures per unit of production for the base year were adjusted in RY2017 to improve accuracy.
  • 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 the external recycling amount.
  • The sales ratio of products that 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
  • Usage ratio of recycled materials (%) in the cast metal products and parts (ductile iron pipes, fittings, machine cast products (engine crankcase, etc.))
  • Targeting 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
  • Major products of products launched onto markets in 2017

The results for Medium-Term Environmental Conservation Targets 2020
