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.

  • 2) Using carbon dioxide capture and storage (CSS) 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 2022 totaled 27.93 million tons, an increase over the previous fiscal year. This was due to the restart of operations of facilities that had been shut down due to malfunction, in addition to a recovery in demand, which had been impacted by the COVID-19 pandemic.
Meanwhile, our crude oil refining energy consumption intensity improved by 0.16 points from the previous fiscal year to 8.92 (oil equivalent consumption volume (kL)/crude distillation unit equivalent throughput (thousand kL)) with the recovery of operations.
In fiscal 2022, 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.

  • *Scope 1 and Scope 2 as defined in the GHG Protocol

Introduction of CO2-Free Electricity at Principal Metals Business Sites

As approximately 60% of the JX Metals Group’s total CO2 emissions come from electricity, in fiscal 2020 it began introducing CO2-free electricity*. In fiscal 2022, the JX Metals Group completed the switch to CO2-free electricity at its major sites in Japan, with the exception of some sites that have contractual restrictions. It is also steadily moving ahead with the switch at its overseas sites.

  • *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 2022, the ENEOS Group spent a total of around 29.4 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
  • 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, we are exploring technologies that will contribute to the realization of a carbon-neutral society. The ENEOS Lab, established at Waseda University as a hub for joint research, is conducting innovative research on CO2 reduction related to hydrogen, battery materials and robotics.

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 financial assistance over a 10-year period in areas ranging from R&D and demonstration projects to social implementation, covering 14 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 2023, the fund’s assets total around 700 million yen, which will make it possible to provide stable grants for approximately 13 years going forward.

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

  • Note:
  • Scope: ENEOS

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* in fiscal 2022 totaled 183.42 million tons.
ENEOS 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.

  • *Scope 3 as defined in the GHG Protocol
Main environmentally friendly products
  • Fuel-efficient lubricants
  • Specialized fluids for electric vehicles and hybrid vehicles
  • Natural gas and LNG
  • Liquid crystal polymers
  • Electricity generation using renewable energy

For more information on our environmentally friendly products, see ENEOS’s environmentally friendly products (available in Japanese only).

Sales of Carbon-Neutral Natural Gas and LNG

In fiscal 2021, ENEOS began selling carbon-neutral natural gas and LNG due to the use of CO2 credits* from overseas forest protection projects, and has been supplying these products to utility gas providers since then.
ENEOS’s carbon-neutral natural gas and LNG utilize CO2 credits generated from forest protection projects in Indonesia and other countries to offset the CO2 generated in processes from natural gas extraction to combustion, reducing it its carbon footprint to net zero. In addition to reducing greenhouse gas emissions on a global scale, ENEOS is also contributing to the creation of local employment and the protection of biodiversity.

  • *CO2 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.
In fiscal 2023, we will introduce a CO2 visualization system that will enable us to manage our CO2 emissions. In March 2023, ENEOS, WasteBox Co., Ltd., and NTT DATA Corporation launched a joint study for construction of the system. The system is being designed to provide the following functions to enable us to more accurately calculate the carbon footprints (CFP)1 of ENEOS petroleum products and manage the greenhouse gas emissions of more than 100 sites.

  • 1)Streamlining statutory reporting of greenhouse gases by improving efficiency of work processes for aggregation of entity-level greenhouse gas emissions
  • 2)Managing the implementation of carbon neutrality plans through monthly forecasting and result management
  • 3)Streamlining per-product CFP calculations and discussions on reduction of per-product CFP

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.
Once the system is in operation, we will provide our customers with CFP data for ENEOS petroleum products, beginning with some lubricants, petrochemical products, and functional materials and then expanding to cover other 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.

  1. 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.
  2. 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.
  3. 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

Tokyo Oi Hydrogen Station
Tokyo Oi Hydrogen Station

Hydrogen is a clean energy source that does not emit CO2 during use. Because it enables the use of renewable energy during the manufacturing process and can be rendered CO2-free (green hydrogen), hydrogen is considered a key form of clean energy for the achievement of carbon neutrality.
As of September 30, 2023, there are around 8,000 fuel cell vehicles (FCVs) in Japan, which has a total of 164 hydrogen stations, 43, or roughly one-third, of which are operated by ENEOS. Looking ahead, the growth of FCVs, especially commercial vehicles such as buses and trucks, is expected due to the long driving range and quick filling times offered by hydrogen. ENEOS is working to develop large-scale hydrogen stations to accommodate these vehicles.
With an eye on the future mass consumption of hydrogen, we are 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).
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 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.

Oil and Gas E&P Using CO2-EOR and CCS Technologies

JX Nippon Oil & Gas Exploration carries out its business activities with attention to the reduction of greenhouse gas emissions, a cause of global warming.
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 3.77 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 2020, together with Japan Organization for Metals and Energy Security (JOGMEC), we concluded a joint study agreement with PETRONAS, Malaysia’s state-owned oil company, for gas field development using CCS (CO2 capture and storage) technology, in which CO2 emitted from gas fields is captured and injected underground.

CCS Business

The Group is preparing to launch Japan’s first large-scale CCS business in fiscal 2030 in cooperation with the government, which aims to achieve carbon neutrality by 2050, and various businesses that are actively working to achieve that goal.
In the Group’s oil and natural gas E&P business, we commercialized a CCS/CCUS business in 2016 in Texas, USA, in which CO2 captured from exhaust gas at a thermal power plant is injected underground. Therefore, we already have the necessary technology and knowledge for geological evaluation and CO2 injection. While maximizing this expertise, we will collaborate with other companies to scale up operations and minimize costs, aiming for the full-scale implementation of CCS.

Specific Initiatives
  • West Japan Carbon dioxide Storage Survey Co., Ltd. established jointly by three companies, Electric Power Development Co., Ltd. (J-POWER), ENEOS, and JX Nippon Oil & Gas Exploration, for the storage of CO2 in western Japan (February 2023)
  • Acquisition of shares of Japan Drilling Co., Ltd., which has offshore drilling technology necessary for CO2 storage (March 2023)
