Climate-related risks and opportunities by considering 4 factors




Regulatory Risk
Risk and Opportunity


Besides, carbon pricing can pose a risk in upstream operation. Particularly, in the case that the origin country of crude oil suppliers mandates the carbon price. This could result in an increase of the Company’s raw material costs. In downstream operations, likewise, the risks of carbon pricing can be posed by the execution of the EU’s Carbon Boarder Adjustment Mechanism (CBAM). This may impact the prices of some petrochemical products of the Company that is exported in the European market.
With these situations, the oil industry business might face challenges in adaptation. Also, the Company may encounter the risks on higher costs and long-term shift towards clean energy. However, the government initiatives present opportunities for the Thaioil Group to formulate its business strategy. For instance, if the government advocates or offers incentives for investing in clean energy ventures, such as hydrogen production or sustainable aviation fuel, it could facilitate Thaioil Group’s adaptation to change its business landscape.
Mitigation Measures
Closely monitoring the progress of regulatory enforcement.
Conducting Sensitivity Analysis for Carbon Pricing.
Joining membership of the greenhouse gas-related associations such as Thailand Carbon Neutral Network (TCNN) and Thailand Business Council for Sustainable Development (TBCSD) to monitor the regulatory enforcements and directions for the private sector.
Monitoring the impacts of carbon prices in case of transmission from crude oil suppliers and conducting appropriate sourcing strategies.
Technological Risk
Opportunity


Mitigation Measures
Conducting feasibility study for the use of carbon capture technology in the production process.
Participating in a feasibility study of applying carbon transportation and storage in the Eastern region with PTT Group.

Seeking business opportunities in New S-curve Business
Market Risk
Opportunity
could cause an uncertainty in business revenue. Besides, the trends of energy transition occurring in many countries may impact future markets while the growing demands of electric vehicles may disrupt the needs for oil and other fossil fuels.
Moreover, the National Electric Vehicle Policy Committee (EV Board) has announced the 30@30 policy. The goal is to produce Zero Emission Vehicle (ZEV) – vehicles emitting zero emissions – at least 30 percent of the total vehicle production by 2030. In 2023, the EV board issued measures to support the use of electric vehicles in Phase 2 or EV 3.5 over a 4-year period (during 2024-2027). These measures are expected to accelerate the rapid behavioural change in consumer behaviour towards ZEVs.
With the growing demand for clean and renewable energy, Thaioil Group has recognized the impacts on its product sales in both the short- and long-terms. However, the energy transition also creates opportunities for the Company to explore new business investment and new products.


Mitigation Measures
Adjusting gasoline production ratio in alignment with the decreasing demands in the future. Increasing the production efficiency of investing in diesel and aviation fuel production through Clean Fuel Project (CFP).
Adjusting the structure of business portfolio to support the future market.

Key Risks
- Impact of carbon pricing from carbon dioxide equivalent emissions in the Company’s production process. The scenario analysis has been conducted in the case that Thailand adopt the GHG Emission Trading Scheme (ETS). The capacity has been limited by the GHG emission of Thaioil Group 2022. The carbon price in 2030 and 2050 is referred to the IEA World Energy Outlook 2021.
- Impact of declining demands on the Company’s products from the shift to use alternative energy (Downstream). The demand for oil products in ASEAN is referred to the IEA World Energy Outlook 2021.
- Impact of carbon pricing from the increasing crude oil price by crude oil suppliers (Upstream). The scenario analysis has been conducted in the case that the suppliers have an impact from carbon taxes and consequently affect the Company’s cost at 100%.

The Physical Scenario
Thaioil Group has assessed physical risks of both acute and chronic impacts from rising global temperature. The scenario analysis has been conducted in the period of 2030, 2040, 2050 across supply chain, covering upstream, existing operating, new operation (including the Clean Fuel Project: CFP), and downstream. Representative Concentration Pathways (RCPs), a recognized climate model of the Intergovernmental Panel on Climate Change (IPCC), has been applied in two scenarios as below:
The RCP 2.6 scenario represents a stringent greenhouse gas reduction measure.
The RCP 8.5 scenario represents a rapid increase in greenhouse gas emissions.
Climate-related risks and opportunities by considering 2 factors


Water Scarcity
Risk



Mitigation Measures
To balance between business interests and stakeholders’ expectations, Thaioil Group has agreed with government agencies to give importance to the community as the first priority during water shortages. This is to ensure the surrounding communities have adequate water irrigation for agriculture and consumption for their daily needs before any allocation to Thaioil Group. Furthermore, Thaioil Group has established a “Long-term Water Supply Strategy 2023–2033” to ensure water security and reduce the risk of water scarcity that may impact both business operations and future expansion projects. Thaioil Group’s water management is summarized as follows:
At the present, Thaioil Group uses two types of water. The seawater is processed to freshwater through the Thermal Desalination unit. The raw water is sourced from two different water distributors namely the Bang Phra Reservoir, which is operated by the Royal Irrigation Department, and the Nong Kho Reservoir, which is operated by the Eastern Water Resources Development and Management Public Company Limited. Both water distributors operate integrated water systems alongside Thaioil Group through aligning practices with government policies or the local context of shared water use in the area. This is to ensure adequate water supply within Thaioil Group’s production processes, such as the cooling tower system, demineralization for steam production, and other production processes. The Company consistently improves and monitors water quality to exceed the required standards before discharging into the environment. To further minimize the impacts on the ecosystem, the circular economy and 3Rs (Reduce, Reuse, Recycle) principles are adopted in water management to maximize the utilization efficiency.
There are ongoing feasibility study projects under the “Long-term Water Supply Strategy 2023–2033” as follows:
1. A study project on installing additional desalination units from six existing units. This project aims to increase the proportion of water consumption from seawater, which is considered an unlimited natural resource, to replace freshwater consumption, which is considered a limited natural resource.
2. A study project on the recycled wastewater from the water treatment plant.
3. A study project on reverse osmosis system for recycling wastewater.
4. A study project on Pattaya wastewater recycle to reuse wastewater in the urban communities.
Moreover, under construction project is as follows:
A raw water utilization project from the private pond

Risks


Mitigation Measures
Predicting and monitoring cyclone events and relevant warning system.
Preparing the production and delivery of products plan in advance before offshore cyclone occurs.
Reviewing and developing emergency measures to prevent cyclone-related harm.
Result of
Financial Impact Assessment (EBITDA)
Key Risk
- Impact of water shortage: In case that the government sector reduces water supply to the Company by 10%, the Company must align its investments with the Long-term Water Supply Strategy. The Company is required to consider increasing the volume of freshwater from private sources and freshwater production from seawater by the Thermal Desalination Unit. Additionally, the Company needs to prepare the water reservation plan in appropriate areas to provide adequate water in the production process. However, these measures could increase production cost.
- Impact of offshore cyclone events: The Company’s revenue could decline from the cyclone event, particularly in the case that the Company is unable to deliver the products through sea freight during the offshore cyclone event. Also, pre and post-cyclone events could disrupt the production process. In the pre-cyclone event, the Company must ensure worker safety and prevent damage to machinery and equipment. In the post-cyclone event, workplace inspections need to be conducted before operating the business as usual.

Carbon Capture Utilization and Storage (CCUS) performance and progress
In 2022, Thaioil Group initiated a preliminary study to identify production units with the potential to implement CCS technology. This study included estimating the investment budget required for installing carbon dioxide (CO2) capture systems, as well as the associated transportation and storage infrastructure, to meet greenhouse gas reduction targets within specified timeframes. Furthermore, since 2022, Thaioil Group has maintained ongoing collaboration with companies in the PTT Group to conduct a feasibility study on CCS technology. This study benchmarks perspectives at both regional and international levels, covering not only the assessment of technology readiness but also evaluations of financial impacts, regulatory support from regional and international frameworks, as well as environmental impacts related to CCUS.
These conceptual studies assess the current and future demand for CCUS services across various sectors.
In 2023, The results of the study were compiled into a comprehensive report on the Eastern Thailand CCS Hub to inform relevant government agencies about policy frameworks and regulatory mechanisms that drive the implementation of CCS in Thailand.
In 2024, the Company, in collaboration with the PTT Group, engaged in discussions with various government agencies and organizations, including the Federation of Thai Industries, the Department of Industrial Works, the Pollution Control Department, and the Marine Department. These discussions aimed to align with Thailand’s climate change goals by promoting relevant policies, legislation, and support frameworks. Additionally, they focused on exploring investment opportunities, securing funding, and analyzing market demand.
Based on a preliminary feasibility study analysis on CCS technology investments, referencing the Longship and Northern Lights projects in Norway, it was found that the capital expenditure (CAPEX) and operational expenditure (OPEX) for CCS technology across the entire supply chain (Levelized Cost) requires significant capital investment1. To enhance the feasibility of CCS project implementation, the Company plans to further investigate and evaluate cost-effective and efficient carbon capture technologies to reduce future costs. Additionally, the Company is focusing on developing CCS business models in collaboration with the PTT Group and other strategic partners, while also exploring and securing funding sources to ensure projects can be delivered within specified timelines and budget constraints. Future studies will focus on CCS technologies. Examples of currently viable capture technology using amine-based solvents absorption and onshore and offshore carbon transport pipelines. These efforts aim to equip the Company with critical insights to enable informed decision-making and strengthen confidence in the successful execution of CCS projects.
Remarks:
1. Referencing the Longship and Northern Lights projects in Norway, it was found that the capital expenditure (CAPEX) and operational expenditure (OPEX) of the CCS project throughout the supply chain (Levelized Cost) are estimated to be more than USD 200 per ton of carbon dioxide equivalent (USD/tCO₂e)
