Tackling 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 that it is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century. With the Paris Agreement, an international framework to tackle climate change, taking effect in November 2016, the world’s movement toward the reduction of greenhouse gases has been accelerating.
 The Kubota Group sees tackling climate change as one of its materiality, and has been advancing initiatives toward the “mitigation” of climate change to reduce greenhouse gas emissions associated with its business activities and “adaptation” to be prepared for the impact of climate change.

  • 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.
  • 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.

Mitigation of Climate Change

1. CO2 Emissions (Scope 1 and Scope 2)

 In RY2017, CO2 emissions were 645 kilotons CO2e, about the same level as the previous reporting year. Meanwhile, CO2 emissions per unit of sales improved by 9.1% compared to the previous reporting year. The improvement in CO2 emissions per unit of sales is mainly due to the measures implemented to reduce CO2 emissions, as well as the reduction of emissions rate at cast iron production sites in Japan, which take large part of per-unit-sales of CO2.

Trends in CO2 Emissions and Emissions Per Unit of Sales
  • CO2 emissions for RY1990 are the emissions from energy sources at Kubota production sites.
  • CO2 emissions (645 kilotons CO2e) include portions of CO2 that were not released into the atmosphere but absorbed as carbon into products such as iron pipe (19 kilotons CO2e).
  • CO2 emissions after RY2013 include greenhouse gases from non-energy sources.
  • CO2 emissions per unit of consolidated net sales
  • Values for RY2013 through RY2015 were corrected to improve accuracy.

2. CO2 Emissions during Distribution

 In RY2017, CO2 emissions during distribution were 44 kilotons CO2e, an increase of 6.1% compared to the previous reporting year. Meanwhile, CO2 emissions during distribution per unit of sales improved by 3.3% compared to the previous reporting year. The increase in CO2 emissions during distribution is mainly due to an increase in the volume of freight traffic, although the Kubota Group continuously promoted various approaches such as improving loading efficiency by combining transportation and realizing a modal shift through the use of ships.

3. CO2 Emissions throughout the Value Chain

 The Kubota Group makes concerted efforts to figure out CO2 emissions throughout the value chain in addition to its business sites. Following guidelines*, we calculate CO2 emissions based on Scope 3, and continue to expand the categories in the Scope of its calculation of CO2 emissions.

4. Measures to Reduce CO2 Emissions

 The Kubota Group has established its Medium- to Long-Term Environmental Conservation Targets and is devoting efforts to reducing CO2 emissions and energy use associated with its business activities. Various initiatives, including eliminating loss in energy consumption through a switch to equipment with higher energy efficiency and proper operation management, and promoting the visualization of power consumption in each process, have been implemented mainly at production sites. At the same time, all global sites have been expanding their use of LED lighting.
 The initiatives implemented during RY2017 include improving the method of temperature control in the melting process, which emits a large amount of CO2, and raising the efficiency of production equipment for processing lines. The introduction of renewable energies has also been accelerating. Kubota Construction Machinery (Wuxi) Co., Ltd. (China) introduced a solar power generation system in RY2015. In RY2017, it generated 1,593 MWh of electricity and reduced CO2 emissions equivalent to approximately 1,047 tons. SIAM Kubota Corporation (Thailand) also introduced a solar power generation system, which started full-scale operation from RY2018.
 As a result of the efforts toward achieving the Medium-Term Environmental Conservation Targets 2020 for CO2 reduction, global production sites achieved a reduction of 26.6 kilotons CO2e in RY2017 compared with the case where countermeasures were not implemented from the base year (RY2014). The economic effects of these measures reached 0.59 billion yen compared to RY2014. CO2 emissions per unit of production in RY2017 improved by 15.2% compared to RY2014.
 We will continue to implement measures to save energy on production equipment and air-conditioning/lighting, as well as to promote the reduction of waste and loss in the use of energy based on the concept of the Kubota Production System (KPS).


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.

Adaptation to Climate Change

Measures to Adapt to Climate Change

 In response to climate change, the Kubota Group has been advancing initiatives in terms of “adaptation” to be prepared for the impact of climate change, as well as the initiatives for “mitigation” aimed at reducing CO2 and other greenhouse gas emissions.
 As part of the measures for adaptation to climate change, business sites have formulated BCPs and disaster response manuals. To be prepared for high tides and torrential rain, they have also installed sump pumps and hold emergency drills.
 Major initiatives in the products and services field are as follows.

  • Provision of tractors that are capable of deep plowing necessary for growing rice in abnormally high temperatures without lowering the quality/yield, and the provision of information useful for soil cultivation, such as the proper distribution of fertilizers appropriate for high-temperature conditions
  • To address water shortage, the provision of management systems using IoT, which contribute to the efficient operation of water supply and sewage treatment systems and treatment plants
  • Provision of tank-submerged type ceramic membrane filtering equipment using membrane technology to facilitate the use of seawater
  • Provision of information for farmers on changes in temperature, precipitation, and the amount of solar radiation, as well as the impact thereof on crops
  • Provision of a water level management service using weather information in collaboration with the NTT Group in the sewerage area
  • As a measure for floods or other disaster caused by abnormal climate, provision of disaster-relief pumper vehicles, ultra-light, emergency sump pump units, piping systems for manhole toilets, and so on
