Environmental Management

Basic Approach

As part of its responsibilities as a corporate group involved in the supply of energy and materials, the ENEOS Group maintains a proper understanding of the impact of its business activities on climate change risks and natural capital. Environmental conservation has been included as a standard in the ENEOS Group Code of Conduct, and the Group has also established a Long-Term Vision and a Carbon Neutrality Plan, and is implementing initiatives for the development of a sustainable society.
In May 2019, ENEOS Holdings signed a statement of support for the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD), and we are working to enhance and expand our disclosures concerning climate change. For details, see Our Response to Climate Change Risks and Opportunities (TCFD).

ENEOS Group Code of Conduct (excerpt)
  1. 3.Environmental conservation
    1. (1)We recognize that we are stewards of the environment and its limited resources. We strive to conserve biodiversity and natural capital, including, but not limited to, water, soil, and the atmosphere, and contribute to the development of a sustainable society.
    2. (2)We strive to promote renewable energy and energy conservation in order to contribute to the development of a decarbonized society.
    3. (3)We strive to contribute to the establishment of a circular economy by reducing, reusing and recycling, while using resources effectively and efficiently.
    4. (4)We strive to take actions to promote sustainable production and consumption for the benefit of society while taking the same actions throughout our value chain, including, but not limited to, resource development, procurement, production, distribution and sales.


In order to facilitate environmental management based on the Group Code of Conduct, the Group has established an environmental management system (EMS) headed by the president of ENEOS Holdings as Group chief executive. Under this system, we regularly confirm the status of achievement of environmental targets and compliance with environmental laws and regulations, and report the status to the ENEOS Holdings Executive Council and the Board of Directors, ensuring that environmental management performance is monitored and supervised by both organizations.
In addition, 89 of the 138 business sites that have adopted the EMS have obtained ISO 14001 certification, a set of international standards for environmental management, for a certification rate of 64%.

We have established the ENEOS Group Tripartite Safety, Health & Environment Committee, chaired by the officer responsible for the Safety, Health & Environment Department at ENEOS Holdings. The committee meets, in principle, twice annually, where it deliberates on environmental targets, plans and performance of ENEOS Holdings and the Group’s principal operating companies and shares information on the status of activities in an effort to improve Group-wide environmental issues.

Plan and Targets

Second Medium-Term Environmental Management Plan

In May 2020, we announced our intention to achieve carbon neutrality in our own emissions by fiscal 2040. As a milestone for this target, we formulated the second Medium-Term Environmental Management Plan (FY2020–FY2022). This plan focuses on three themes: “I. Contribution to a low-carbon society,” “II. Contribution to a recycling-oriented society” and “III. Contribution to environmental protection.” The plan sets out detailed initiatives for each of these themes.

Carbon Neutrality Plan

In May 2020, the Group announced its intention to achieve carbon neutrality in its own emissions by fiscal 2040, and in May 2022 released its Carbon Neutrality Plan, taking into account domestic and international trends. The following year, in conjunction with the formulation of our third Medium-Term Management Plan (FY2023–FY2025), we formulated a new Carbon Neutrality Plan, which we announced in May 2023. The new plan consists of two pillars; namely, reduction of our greenhouse gas emissions and contribution to the reduction of society’s greenhouse gas emissions.

Overview of the ENEOS Group’s Environmental Impact

Input-Output of the ENEOS Group (Results from Fiscal 2022)

  • Notes:
  • Fuel consumption, electricity consumption, and GHG emissions are calculated based on the Act on Promotion of Global Warming Countermeasures. From FY2022, fuel consumption and GHG emissions are calculated taking into account electricity sold and heat sold. GHG emissions from the consumption of electricity are calculated using emission factors by operator.
  • Scope 3 emissions are calculated based on the Basic Guidelines on Accounting for Greenhouse Gas Emissions Throughout the Supply Chain ver. 2.5. Data covers ENEOS.
  • GHG emissions associated with “Category 11: use of sold products” are calculated based on the latest petroleum product sales volumes.

Major Initiatives

External Engagement Activities for a Decarbonized Society

The entire world must work together to achieve the Paris Agreement and the 1.5°C target, and government and policy will play an extremely large role in this. As such, the Company is involved with and contributes to the formulation of policy recommendations by actively participating in government initiatives, as well as economic organizations and trade associations and their activities.
Organizations with a particularly strong relationship with the Company and influence over climate change policy are government bodies the Ministry of Economy, Trade and Industry (METI) and Ministry of the Environment (MOE), and trade associations the Japan Business Federation (Keidanren) and the Petroleum Association of Japan (PAJ). Through collaboration and advocacy with these government bodies and trade associations, we are working to ensure that policy, technological innovation, the orientation of society and customer needs are aligned toward the achievement of carbon neutrality by 2050.

Environmental Education

With the aim of raising environmental awareness even further, the Group distributes environmental newsletters, holds e-learning sessions and provides regular classification-leveled education, training and drills for all employees to instill awareness of the Group’s basic environmental policies and various laws and regulations, and also to ensure basic knowledge of the environment.

Environmental Audits

All business sites that have obtained ISO 14001 certification are subject to regular internal audits based on the requirements of the standard in order to confirm and evaluate the effectiveness and conformance of their EMS activities. They also undergo an annual review by a third-party certification body to maintain their certification.

Preventing Environmental Accidents

As in fiscal 2021, there were no environmental accidents at our manufacturing sites in fiscal 2022.
