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. Moreover, a new phase of the Paris Agreement - an international framework for tackling climate change - will kick off in 2020, which indicates that the initiatives of individual companies to reduce greenhouse gases are growing increasingly important.
 The Kubota Group sees tackling climate change as one item of materiality and has been advancing initiatives toward the “mitigation” of climate change by reducing greenhouse gas emissions mainly through energy-saving activities and the introduction of renewable energy sources and “adaptation” to be prepared for the impact of climate change.

  • 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.
  • 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.

Mitigation of Climate Change

1. CO2 Emissions (Scope 1 and Scope 2)

 In RY2019, CO2 emissions were 630 kilotons CO2e, a decrease of 2.6% compared to the previous reporting year. Additionally, CO2 emissions per unit of sales improved by 6.1% compared to the previous reporting year. In addition to the implementation of reduction measures, these are mainly due to the improvement of the emission coefficients for each electricity utility and a reduction in production volume at cast iron production sites in Japan.

Trends in CO2 Emissions and Emissions Per Unit of Sales
  • CO2 emissions (630 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 include greenhouse gases from non-energy sources.
  • CO2 emissions per unit of consolidated net sales. The Kubota Group adopted International Financial Reporting Standards (IFRS) instead of accounting principles generally accepted in the United States of America from RY2018.
  • CO2 emissions for RY2016 and RY2017 and CO2 emissions per unit of sales for RY2017 were corrected to improve accuracy.

  • Energy use per unit of consolidated net sales. The Kubota Group adopted International Financial Reporting Standards (IFRS) instead of accounting principles generally accepted in the United States of America from RY2018.

2. CO2 Emissions during Distribution

 In RY2019, CO2 emissions during distribution were 41 kilotons CO2e, a decrease of 6.9% compared to the previous reporting year. Additionally, CO2 emissions during distribution per unit of sales improved by 14.1% compared to the previous reporting year. The Kubota Group continuously promotes various initiatives, including such as improving loading efficiency 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- and Long-Term Environmental Conservation Targets and is devoting efforts to reducing CO2 emissions and energy use associated with its business activities.
 We have also established medium-term reduction measure implementation plans, which are reviewed every year by each production site. When the plans are reviewed, Internal Carbon Pricing* is introduced to calculate their effect on reducing CO2 emissions and energy consumption, as well as the investment cost for the amount of CO2 reduced, in the capital expenditure plans. The effectiveness and economical rationality of each project are identified from an environmental standpoint and used as resources for making investment decisions.
 Some of the specific reduction measures that have been implemented include 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. At the same time, all global sites have been expanding their use of LED lighting. In RY2019, initiatives included a change in fuel for production equipment and heaters.
 We are also accelerating the introduction of renewable energy. In RY2019, a new solar power generation system came online at the Kubota Sakai Rinkai Plant. This brought the renewable energy consumption of the entire Group to 2,604 MWh, an increase of 8.0% compared to 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 38.8 kilotons CO2e in RY2019 compared with the case where countermeasures were not implemented from the base year (RY2014). The economic effects of these measures reached 1.14 billion yen compared to RY2014. CO2 emissions per unit of production in RY2019 improved by 17.1% compared to RY2014.
 We will continue to implement measures to save energy on production equipment and air-conditioning/lighting, as well as promote measures to reduce waste and loss in the use of energy based on the concept of the Kubota Production System (KPS) and expand the use of renewable energy.

Adaptation to Climate Change

Measures to Adapt to Climate Change

 Various impacts are being felt by the progression of climate change, such as the frequent occurrence of weather disasters, changes in agricultural practices, and an increase in the number of heat stroke cases. The response to climate change needs to include measures to reduce greenhouse gas emissions, as well as to avoid or reduce damage brought on by climate change.
 As part of its strategy to adapt to climate change, the Kubota Group is implementing a number of initiatives at its business sites and in its products and services.
