Medium- and Long-Term Environmental Conservation Targets and Results

As extreme weather events and other impacts of climate change continue to materialize, the global movement aimed at reducing greenhouse gases is growing 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 in light of various recent social developments, such as SDGs and the Paris Agreement, as a sustainable company, the Kubota Group has challenged itself to achieve zero environmental impact in its Environmental Vision for 2050. Moreover, to promote systematic reduction of environmental impacts, we have been promoting environmental activities by formulating our medium- and long-term targets for environmental conservation. We formulated the Long-Term Environmental Conservation Targets 2030 in 2016, and Medium-Term Environmental Conservation Targets 2025 in 2020. Now, we have revised the Long-Term Environmental Conservation Targets 2030, expanding the boundary of our initiatives and increasing the target values. Toward achieving these targets, the Group is advancing systematic initiatives in both the production and product development stages.

Long-Term Environmental Conservation Targets 2030 and Results

1. Mitigating and Adapting to Climate Change13.CLIMATE ACTION

The shift to a decarbonized society has been accelerated, with each country declaring substantially zero emissions of CO2 and carbon neutrality. In its Environmental Vision, the Kubota Group announced its commitment to take up the challenge of achieving carbon neutrality by 2050. Based on these global trends and the image for the company expected by society in the future, in our Long-Term Environmental Conservation Targets 2030, we have expanded the scope of our CO2 reduction targets from the Kubota Group in Japan to a global scope, and revised our targets. We will continue energy-saving activities to reduce energy consumption at our sites, reduce CO2 emissions through fuel conversion by adopting electric furnaces and so forth, and by expanding our use of renewable energies, we will promote initiatives to achieve carbon neutrality.

2030Targets Reduce CO2 emissions from the Kubota Group* by 50% compared to the base year FY2014.
Result In FY2021, CO2 emissions of the Kubota Group* were reduced by 16.5% compared to the base year FY2014.
  • CO2 emissions refer to Scope 1 and 2 emissions from all Kubota Group sites (100%) and include greenhouse gases from non-energy sources
  • Trends in CO2 Emissions of the Kubota Group in Japan

  • CO2 emissions of companies that have been acquired or sold have been adjusted retroactively to before the acquisition or sale. CO2 emissions that have not been adjusted are 714 kilotons CO2e in 2014, 674 kilotons CO2e in 2015, and 647 kilotons CO2e in 2016, 645 kilotons CO2e in 2017.

2. Efforts to Develop Environment-friendly Products12.RESPONSIBLE CONSUMPTION & PRODUCTION

Goal Increase the sales ratio of Eco-Products* 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-Products* was 68.0% in FY2021.
  • 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 2025 and Results

Since FY2021, the Group has been working to achieve the Medium-Term Environmental Conservation Targets 2025. In addition to the indicators set out in our Medium-Term Environmental Conservation Targets 2020, we have added the target of increasing the renewable energy usage ratio towards realizing a carbon-free society. Furthermore, in view of the growing global issue of ocean pollution by disposable plastics, we have added a qualitative target of improving resource efficiency. We have also set a qualitative target for systematically advancing efforts on wastewater management and conserving biodiversity. In the product segment, we set a new target relating to displaying the materials of new parts with a view to promoting recycling, along with new targets for responding to regulations on vehicle exhaust gas emissions aimed at complying with exhaust gas regulations. Our results for FY2021 are shown in the following table.
