and emission of greenhouse gas.
Pioneer group addresses the sustainable management to achieve the carbon neutrality specifying the “climate change” as one of the most important social issues. As for the Greenhouse gas emission (Scope1*1+Scope2*2) from our business operation, we have set a milestone of 42% reduction by the fiscal year ending in March 2031 from base year of the fiscal year ended in March 2021. For Scope 3*3, we are targeting Category 1 and 11, which account for the majority of emissions in our operations, with the goal of a 42% reduction. In Category 1, we will also initiative supplier engagement activities for the approximately 10% of our suppliers to promote and support the setting of science-based greenhouse gas (GHG) emissions reduction targets.
To achieve this GHG emissions reduction target, we will actively reduce our dependence on fossil fuels, promote the transition to renewable energy and energy conservation, and utilize future technological innovations.
We will also cooperate with our customers then address to reduce it aggressively as for the lifecycle CO2 regarding products and services. Moreover, in the mobility field, we have begun providing solution services which contribute to drastic challenges in vehicle usage and logistics, thereby contributing to carbon neutrality and our business growth. In order to enhance information disclosure regarding these climate change, we strive to organize our sustainable business management strategies and prepare disclosure of environmental information in line with international initiatives such as TCFD and GRI.
The above GHG emissions reduction targets have been certified by SBTi.
To ensure we promote these activities effectively, we believe internal environmental education is also essential. Through regular information sharing and environmental education within our company, we will raise awareness of environmental issues by employees and strive to achieve early realization of carbon neutrality.
Scope 1: An organization’s direct GHG emissions (fuel combustion, industrial processes, etc.)
Scope 2: Indirect emissions associated with the use of electricity, heat, or steam supplied from another company.
Scope3: Indirect greenhouse gas (GHG) emissions that occur throughout a company's value chain.

We aim to reduce GHG emissions by 42% by the fiscal year ending March 2031 (FY31), compared to FY21 levels, and to achieve carbon neutrality by 2050. To accomplish this goal, we have created a roadmap outlining GHG emission reduction measures and projected reduction trends.
We have established an environmental management system and are advancing activities centered on renewable energy conversion, energy conservation efforts, and electrification to achieve our 2030 goals. Furthermore, we will continue to thoroughly eliminate wasteful energy in production processes through measuring of energy usage visualization, while systematically implementing the switch to energy-saving equipment. Regarding utilizing of renewable energy, we have introduced on-site PPAs at some overseas sites and begun switching to green power at domestic sites, contributing to GHG emissions reduction. We plan to pursue renewable energy adoption and expand generation capacity, considering the specific circumstances of each country and region, including sites where these measures have not yet been implemented. Furthermore, our mid-term business plan anticipates increased production volumes due to business expansion, which is expected to lead to higher energy consumption. To reduce GHG emissions even as energy consumption rises, we will aim for early target achievement while considering multifaceted approaches, such as introducing an Energy Management System (EMS) and utilizing renewable energy certificates.
In September 2026, in response to growing societal demands and stakeholder expectations, we revised our roadmap to accelerate renewable energy adoption and other decarbonization measures, aiming for greater reductions in GHG emissions.
We strive to enhance the transparency and reliability of the GHG emissions data we disclose.
In August 2026, the Pioneer Group obtained independent third-party assurance for its greenhouse gas (GHG) emissions data. Please refer to the Third-Party Assurance Report below for details. Please note that the report is currently available in Japanese only.
The Pioneer Group sets greenhouse gas reduction targets for our sites and facilities in consideration of commitments made to various stakeholders.
While major Japanese sites promote energy conservation activities in accordance with Japan's Energy Conservation Act framework, some Japanese sites place particular emphasis on climate change initiatives promoted by local governments.
At the Kawagoe Site, we participate in the Saitama Prefecture Global Warming Countermeasure Plan System and the Target-Setting Emissions Trading Scheme. Through continuous emission reduction activities, we have achieved the required reduction targets for the manufacturing sector without relying on emissions trading.
In order to reduce the CO2 emission amount in entire products lifecycle, we conduct LCA (life cycle assessment), analyze the CO2 emission amount, and conduct visible management to confirm reduction of emission amount compared with previous products, to address to prevent the global warming.
The life cycle CO2 emissions with 7.5% for the 2022 Cyber Navi model and 6.6% for the 2023 Raku Navi model were reduced comparing to the previous model by reducing the number of parts and weight. Newly developed models are also developed using LCA process.
Pioneer group is expanding our utilization of the renewable energy as one of our activities to reduce GHG emissions.
At our production plant in Thailand, we installed solar panels on the roof starting in November 2022 and introduced solar power generation through a PPA model. This now supplies 7% of the plant's total electricity from renewable energy.
Since April 2024, we have switched 100% of the electricity used in buildings related to production activities at our site to effectively renewable electricity, covering 73% of the site's total electricity consumption.
In April 2025 and April 2026, we further expanded the scope of adoption, increasing coverage to 99% of the site's total electricity consumption.
We began introducing renewable energy-based electricity in April 2022 and have steadily expanded its use. Since April 2026, electricity effectively sourced from renewable energy has been adopted across the entire site.
Since January 2025, approximately 28% of the factory's total electricity consumption has been supplied by renewable electricity generated through an on-site solar power PPA.
The office building (Bunkyo Green Court, Bunkyo-ku, Tokyo) where the head office is located uses 100% CO2-free electricity produced from substantial renewable energy. In addition, other locations such as the office building (Suginami-ku, Tokyo) where Pioneer Sales and Marketing Corporation is located are also proceeding to use the substantial CO2-free electricity.
