Stopping Climate Change

The Fifth Assessment Report by the Intergovernmental Panel on Climate Change (IPCC), states that the 'warming of the climate system is unequivocal' and there is an extremely high possibility that the impact of human activities is one of the contributing factors. Additionally, the "Paris Agreement" was entered into force in November 2016 and the world's movement toward the reduction of greenhouse gas has been increasingly activated. The Kubota Group is engaged in initiatives to reduce CO2, placing a focus on energy-saving activities in order to prevent global warming.

  • 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.
  • 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. CO2 Emissions (Scope 1 and Scope 2)

In RY2016, CO2 emissions were 647 kilotons CO2e, a decrease of 3.9% compared to the previous reporting year. Additionally, CO2 emissions per unit of sales improved by 0.6% compared to the previous reporting year. The decrease in CO2 emissions is mainly due to the reduction of production volume at cast iron production sites in Japan. We are continuously promoting the energy-saving initiatives for production equipment, lighting, etc., fuel conversion, and various other measures.
 The Long-Term Environmental Conservation Targets 2030 upholds a target of reducing the CO2 emissions of the Kubota Group in Japan by 30% compared to RY2014 by 2030. The CO2 emissions in RY2016 were 474 kilotons CO2e, a decrease of 11.1% compared to RY2014.

Trends in CO2 Emissions and Emissions per Unit of Sales
  • CO2 emissions for RY1990 are the emissions from energy sources at only Kubota production sites.
  • CO2 emissions (647 kilotons CO2e) include portions of CO2 that were not released into the atmosphere but absorbed as carbon into products such as iron pipe (24 kilotons CO2e).
  • CO2 emissions after RY2012 include greenhouse gases from non-energy sources.
  • CO2 emissions per unit of consolidated net sales.

3. CO2 Emissions during Distribution

In RY2016, CO2 emissions during distribution were 42 kilotons CO2e, a decrease of 5.2% compared to the previous reporting year. Additionally, CO2 emissions during distribution per unit of sales improved by 2.0% compared to the previous reporting year. The decrease in CO2 emissions during distribution is mainly due to the reduction in the volume of freight traffic. We are continuously promoting various approaches such as improving loading efficiency by combining transportation and realizing a modal shift through the use of ships.

4. CO2 Emissions throughout the Value Chain

The Kubota Group has been working to figure out the CO2 emission from the entire value chain and disclosing a part of Scope 3 emissions.

Example Activities of Each Scope
The Kubota Group has been working to figure out the CO2 emission from the entire value chain and disclosing a part of Scope 3 emissions.
  •  Scope 1: Direct GHG emissions from businesses themselves
  •  Scope 2: Indirect emissions associated with the consumption of electric power, heat, and steam
          supplied by others
  •  Scope 3: Indirect emissions other than scope 2 (others emissions related to business activities)

5. Activities to reduce CO2 emissions

The maximum power usage for the overall plant (hourly transitions) is visualized as a graph. On some of the production lines, they have worked on visualization of power usage in units of facilities to lead to improvements.

The empty spaces of vehicles are effectively utilized through mixed loading of products with multiple projects with different load handling measures. We will continue to accumulate the know-how and records that would lead to energy saving in the field of logistics.
