Prevention of Global Warming
Basic Approach
The ENEOS Group is reducing CO2 emissions across the entire supply chain in order to contribute to the development of a decarbonized society.
To reduce our greenhouse gas emissions, we are focusing on energy conservation in our business activities. We are also helping to reduce the overall greenhouse gas emissions of society through the expansion of our renewable energy business, early practical implementation of hydrogen and carbon-neutral fuels, and development and sales of environmentally friendly products that have a lower environmental impact.
For our company-wide initiatives to address climate change and TCFD-related information, see Our Response to Climate Change Risks and Opportunities (TCFD).
Structure
For information on our structure, see Environmental Management.
In May 2024, we established the Carbon Neutrality Promotion Committee, chaired by the CTO, to promote carbon neutrality across the Group. The committee updates the basic strategies in response to the business environment, while the operating companies formulate specific action plans based on these basic strategies.

To reach these targets, we are focusing our efforts in three main areas.
- 1) Curbing Group greenhouse gas emissions by improving the energy efficiency of our manufacturing and business operations through energy saving, fuel conversion, and the use of renewable energy.
- 2) Using carbon dioxide capture and storage (CCS) for emissions remaining after the above measures are carried out, and storing the captured CO2 underground.
- 3) Any remaining greenhouse gas emissions after the above two measures will be removed through forest absorption and other natural absorption methods.
Major Initiatives
Energy Conservation at Production Sites
The Group’s refineries and plants are pursuing energy conservation through measures such as increasing the number and efficiency of heat exchangers and introducing higher efficiency rotary equipment.
The Group’s GHG emissions (Scope 1+2)* in fiscal 2023 totaled 25.41 million tons, down from the previous fiscal year. In addition to improvements in the efficiency of operations, this decline was attributed to the reduction in refinery operations due to a decline in domestic demand and refinery troubles, along with a reduction in the operation of facilities for generating electricity to be sold due to fluctuations in electricity market prices.
Meanwhile, our crude oil refining energy consumption intensity worsened by 0.28 points from the previous fiscal year to 9.20 (oil equivalent consumption volume (kL)/crude distillation unit equivalent throughput [thousand kL]) due to the reduction in refinery operations.
In fiscal 2023, the Group invested around 0.61 billion yen in facilities for energy conservation. Going forward, we remain committed to pursuing greater energy conservation by introducing energy-saving technologies and optimizing operations at our refineries and smelters.
- *Calculated in accordance with the Act on Promotion of Global Warming Countermeasures.
Introduction of CO2-Free Electricity at Principal Metals Business Sites
Approximately 60% of the JX Advanced Metals Group’s total CO2 emissions (Scope 1+2) come from electricity. In fiscal 2020 it began introducing CO2-free electricity* to reduce its CO2 emissions. In fiscal 2023, the JX Advanced Metals Group completed the switch to CO2-free electricity at most of its sites in Japan and overseas.
- *Electricity derived from effectively non-fossil power sources that do not use fossil fuels and do not emit CO2, and have an adjusted CO2 emission factor of 0.00 t-CO2/kWh. In addition to power generation from renewable energy such as hydro power, wind power, and solar power, nuclear power generation may also be included.
Initiatives in Research and Development
The Group is moving forward with research in the following fields in order to realize energy transitions.
In fiscal 2023, the ENEOS Group spent a total of around 32.1 billion yen on research and development.
- Technical development for the manufacture, storage, transport, and supply of CO2-free hydrogen derived from renewable energy
- Technical development for the manufacture of synthetic fuels from CO2-free hydrogen and CO2
- Technical development for the manufacture of hydrogen and the optimization of storage battery operation plans, which contribute to the effective use of renewable energy
- Technical development and feasibility study on biofuels
- Technical development on recycling of plastic resources and used tires
- Rationalization and streamlining of oil refining processes using digital technology, etc.
- Development of environmentally friendly products (fuel-efficient automotive lubricants, etc.)
Initiatives of ENEOS Lab with Waseda University as a Joint Research Base
In November 2019, ENEOS concluded an agreement with Waseda University on comprehensive collaboration activities to promote innovation toward achieving a sustainable society. Through multi-disciplinary open innovation, from innovative technology to humanities and social sciences that indicate how the social implementation of technology should be, we are exploring the seeds that will contribute to the realization of a carbon-neutral society.
Development of Manufacturing Technologies for Synthetic Fuels Derived from Renewable Energy
ENEOS is working on the development of manufacturing technology for synthetic fuels that can replace fossil fuels such as jet fuel, gasoline, and diesel to achieve carbon neutrality in a wide range of fields, such as aircraft and vehicle mobility and raw materials for chemicals and lubricants.
Synthetic fuels are carbon-neutral fuels produced using CO2-free hydrogen derived from renewable energy and CO2, which means that they can reduce CO2 emissions throughout the product lifecycle. In addition, as their properties are equal to those of conventional fossil fuels, these synthetic fuels can be acceptable in existing vehicles, refinery facilities, and distribution routes, meaning they will play a vital role in realizing energy transitions.
ENEOS aims to establish manufacturing technologies for synthetic fuels early and their social implementation with the support of the Green Innovation (GI) Fund*, which was adopted in April 2022.
- *A fund administered by the Japanese government that provides support to companies working to address management issues to help reach Japan’s goal for carbon neutrality by 2050. The fund offers ongoing financial assistance over a 10-year period in areas ranging from R&D and demonstration projects to social implementation, covering fields in energy-related industries, including the hydrogen and ammonia fuel industries; transportation and manufacturing-related industries; and household and office-related industries.
Synthetic Fuels Production Process
Supporting Research on Hydrogen Energy Supply through the ENEOS Hydrogen Trust Fund
ENEOS established the ENEOS Hydrogen Trust Fund in March 2006 in order to help speed up the realization of a hydrogen society.
The fund is Japan’s first public trust specializing in supporting research on the supply of hydrogen energy. The fund is large enough that a stable supply of research grants worth 50 million yen (up to 10 million yen per project) can be provided for around 30 years to support innovative and pioneering basic research into hydrogen energy supply systems. As of June 2024, the fund’s assets total around 600 million yen, which will make it possible to provide stable grants for approximately 12 years going forward.
Developing Manufacturing Technologies for Bioethanol (Cellulosic Ethanol)
In the journey to carbon neutrality, bioethanol is expected to be used in various applications such as automobile fuels and raw materials for chemical products. In recent years, it has also attracted attention as a raw material for sustainable aviation fuel (SAF). On the other hand, the bioethanol produced around the world today comes mainly from food crops such as sugarcane and corn, raising concerns that it may compete with food.
ENEOS is developing technology for producing bioethanol (cellulosic ethanol) using cellulose resources that do not compete with food, such as woody biomass like pulp and used paper, as raw materials. At the end of 2023, ENEOS concluded a joint development agreement with TOPPAN Holdings Inc., aiming for commercialization through a project combining the preprocessing process developed by TOPPAN Holdings using hard-to-recycle used paper as a raw material and the ethanol continuous production process developed by ENEOS.
In addition, ENEOS Corporation, Suzuki Motor Corporation, Subaru Corporation, Daihatsu Motor Co. Ltd., Toyota Motor Corporation, Toyota Tsusho Corporation, and Matsuda Motor Corporation are jointly participating in the Research Association of Biomass Innovation for Next Generation Automobile Fuels to promote research on production technology for bioethanol fuels for automobiles.
Initiatives in Procurement and Logistics
With regard to marine transportation, which primarily involves the transport of crude oil to Japan, ENEOS is making active efforts to use oil tankers with superior delivery efficiency and fuel efficiency, and to improve fuel consumption by optimizing transportation routes and controlling navigation schedules and speeds.
Regarding land transportation, in addition to consolidating oil depots and improving the distribution efficiency of tank trucks, we are working to reduce fuel consumption through efforts such as insisting that drivers turn off their engines when stopped.
CO2 Emissions from Domestic Transport
- Notes:
- Scope: ENEOS
- Domestic transport based on the Act on Rationalizing Use of Energy and Shifting to Non-fossil Energy (Energy Conservation Act)
Distribution Stage Initiatives
ENEOS is actively implementing power-saving measures at its service stations nationwide through efforts such as the installation of solar panels and the adoption of LED lighting.
Consumption Stage Initiatives
The Group’s CO2 emissions from the use of sold products (Scope 3) in fiscal 2023 totaled 166.00 million tons.
The ENEOS Group is working to reduce CO2 emissions at the consumption stage through the development and sale of environmentally friendly products, which contribute to a lower environmental impact. We have specified standards and procedures for certification of our environmentally friendly products and services and manage these appropriately.
Main environmentally friendly products
- Fuel-efficient/high-performance multipurpose lubricants
- Specialized fluids for electric vehicles and hybrid vehicles
- Natural gas and LNG
- High-performance cleaning agents
- Liquid crystal polymers
- Electricity generation using renewable energy
Sales of Carbon-Offset Natural Gas and LNG
In fiscal 2021, ENEOS began selling carbon-offset1 natural gas and LNG through the use of CO2 credits2 from overseas forest protection projects, and is supplying these products to utility gas providers.
ENEOS’s carbon-offset natural gas and LNG utilize CO2 credits generated from forest protection projects to reduce greenhouse gas emissions on a global scale. ENEOS is also contributing to the creation of local employment and the protection of biodiversity through these efforts.
- 1The CO2 emitted in the process from extraction to combustion of natural gas is offset to virtually zero.
- 2CO2 credits attested by a highly reliable verification institution for CO2 reduction effects generated by environmental conservation projects.
Working with Business Partners (CSR Procurement)
We implement CSR procurement, in which we take into account social impacts, such as effects on the environment, when purchasing materials and other goods and services.
For details, see Supply Chain Management.
Visualizing CO2 to Reduce Greenhouse Gas Emissions
We are working toward the visualization of greenhouse gas emissions in order to reduce these emissions in the Group and in society.
ENEOS established a CO2 visualization system because it is important to determine emissions in a timely manner in order to reduce emissions at its refineries. We established this system to enable centralized management of company-wide emissions and calculation of emissions (carbon footprint: CFP1) for each product. This is the first CFP calculation in the domestic petroleum industry that uses real data obtained at refineries.
The system will be used to streamline statutory reporting, manage the implementation of plans through monthly forecasting and result management, and provide CFP data to customers. In 2024, we started providing CFP data for some products to customers, and we plan to gradually expand the scope of the applicable products.
The development of this system aims to achieve unified monitoring and management of carbon information on a per-product basis, analyze the impact that decarbonization initiatives in manufacturing has on CFP and visualize CFP at the new product planning stages, and create business opportunities by highlighting the environmental value of low-carbon products.
Our CFP data will be “cradle to gate2,” meaning it will cover all greenhouse gas emissions from raw materials procurement to product shipment. We will use the life cycle assessment (LCA) method3 to calculate emissions associated with material procurement and product manufacturing.
- 1Carbon footprint of products (CFP) is a system for converting greenhouse gas emissions throughout the life cycle of a product or service, from the procurement of raw materials to manufacturing and beyond, to CO2.
- 2Refers to the process from raw materials procurement to production within the life cycle stages, comprising raw materials procurement, manufacturing, distribution, sales, use and maintenance, disposal and recycling.
- 3LCA (life cycle assessment) methodology involves quantitatively evaluating the environmental effects of product manufacturing throughout the entire life cycle from procurement of raw materials to manufacturing, transport, use, and disposal.

Establishment of a Hydrogen Supply Chain
Hydrogen has the potential to contribute to decarbonization in a wide range of economic activities in power generation, transportation, and other industrial sectors. We see hydrogen as one of the promising next-generation energy sources that holds the key to achieving carbon neutrality.
First, in the transportation sector, there are around 8,500 fuel cell vehicles (FCVs) (as of July 31, 2024), and approximately 160 hydrogen stations located nationwide in Japan. ENEOS operates 35 of these facilities (as of July 31, 2024). The growth of FCVs as commercial vehicles is expected due to factors such as their hydrogen refueling time and driving range. The Japanese government has prioritized support for commercial vehicles in its Basic Hydrogen Strategy, and we are also considering the development of hydrogen stations in line with this strategy. In addition, as part of our carbon neutrality efforts, at some hydrogen stations we have introduced water electrolysis on-site and are selling CO2-free hydrogen using electricity derived from renewable energy.
Furthermore, with an eye on the future mass consumption of hydrogen, including in power generation and industrial fields, ENEOS is implementing a number of collaborative projects with local governments and leading companies in Japan and overseas for the early establishment of a supply chain for transporting and supplying Japan with green hydrogen produced overseas, where there is abundant renewable energy and other resources. As part of this effort, we are focusing on methylcyclohexane (MCH), a hydrogen carrier, in order to transport green hydrogen from overseas to Japan in large quantities and with high efficiency. We are now working on the development of our proprietary Direct MCH® technology, which contributes to cost reduction (see the news release for details).
Additionally, ENEOS refineries have the potential to serve as hubs for the stable supply of hydrogen due to the fact that they already have expertise in safely handling large quantities of hydrogen, can utilize existing infrastructure, such as ports, piers and tanks, and are located near power plants and steel mills, which are expected to require large amounts of hydrogen. We will fully utilize these advantages in the development of a hydrogen supply chain.

Domestic CCS Value Chain of ENEOS
Oil and Gas E&P Using CO2-EOR and CCS Technologies
ENEOS Xplora carries out its business activities with attention to the reduction of greenhouse gas emissions.
The company is taking part in a project in the state of Texas in the United States to increase output from a depleted oil field by injecting CO2 captured from the flue gas of a thermal power plant. Since April 2017, a total of 4.30 million tons of CO2 has been injected into the oil field through this project, greatly contributing to increasing oil output and lowering greenhouse gas emissions using CO2-EOR (enhanced oil recovery) technology.
In March 2024, ENEOS Xplora signed a plan with Malaysia's state-owned oil company PETRONAS and PETRONAS Carigali Sdn. Bhd., a wholly-owned subsidiary of PETRONAS, for the production of five undeveloped gas fields containing high concentrations of CO2 off the coast of Peninsular Malaysia, and also signed a joint operation agreement with PETRONAS Carigali. This is a combination of conventional development and CCS, in which CO2 captured from gas fields is injected underground, with the aim of developing low-carbon oil and natural gas.
Forest Absorption (Increase of Natural Absorption of CO2)
The Group utilizes natural absorption from forests and other sources as an important means of removing CO2. In order to achieve carbon neutrality in our emissions by fiscal 2040, we are implementing initiatives to create and utilize forest-derived carbon credits in Japan and overseas.
