CPC Corporation, Taiwan

In response to domestic and international net-zero emission trends, CPC, under the guiding principles of "High-value Petrochemical," "Low-Carbon Emission," and "Lean-Renewable Energy," is actively developing technologies for hydrogen energy, geothermal energy, solar energy, and carbon capture, utilization, and storage, with the targets of reducing carbon emissions by 50.2% by 2032 compared to 2005 levels and achieving net-zero emissions by 2050. 

Based on the outcomes of risk identification exercise and international trends, CPC introduces climate change action plans along with short-, medium-, and long-term performance indicators for greenhouse gas management, energy/resource management, water resource management, and pollution control, which are examined regularly for target attainment and progress. CPC also follows the “GHG Protocol” and surveys direct emissions (Scope 1) as well as indirect emissions (Scope 2) of greenhouse gases to determine the effect of its operations and any potential impacts. Outcomes of the greenhouse gas survey have been certified for ISO 14064-1. 

As a support to the national carbon reduction goals outlined in the Climate Change Response Act, CPC designated 2005 as the baseline year, in which it measured greenhouse gas emission at 11.58 million MT (carbon dioxide equivalent). CPC has since surveyed Scope 1 and Scope 2 greenhouse gas emissions on a yearly basis, and made calculations by following the Ministry of Environment’s Greenhouse Gas Emission Coefficient Sheet for guidelines, or using proprietary coefficients as a priority. GWP values are adopted according to Ministry of Environment’s rules. In 2024, CPC’s greenhouse gas emission intensity was 6.38 metric tons CO₂e per NT$1 million in revenue. The overall total greenhouse gas emissions have been reduced by 39.59% compared to 2005. 

CPC’s main emitting plants and other units’ emission proportions in 2024 are shown in the figure below.

Use and management of energy

In response to the international call for low-carbon transition and in line with the net-zero emission target declared by the Taiwanese government, CPC, as the largest oil and gas energy supplier in Taiwan, is fully aware of its significant responsibility in environmental protection and sustainable development. Therefore, CPC actively participates in carbon reduction actions and promotes the implementation of deep energy-saving programs to enhance energy efficiency. The types of energy used by CPC include electricity, natural gas, steam, fuel gas, liquefied petroleum gas, and fuel oil. In 2024, the total energy consumption (in heat value) of CPC’s major production plants reached 92.9 million GJ, with the highest heat value consumption from fuel gas. Based on this, the energy intensity in 2024 was 84.66 (Total Energy Consumption(GJ) / NT$ Million Revenue).  

Use of renewable energy 

In response to the Renewable Energy Development Act and its sub-regulation “Regulations on the Installation of Renewable Energy Power Generation Equipment for Electricity Users with Contract Capacity Above a Certain Level,” a total of six CPC units are subject to regulation and have planned solar PV system sites. In 2024, newly added solar PV system capacity reached 8.223 MW. The sites are spread across Taiwan and outlying islands, including gas station rooftops, oil supply centers, refinery and petrochemical plant areas, and office building rooftops, in compliance with each unit’s legally mandated renewable energy obligation. 

In 2024, the amount of renewable energy generated by solar power stations was 15.62 million kWh. Among the 270 solar PV system sites, 256 were self-use sites. A total of 21 renewable energy site certifications were obtained, and 9,719 renewable energy certificates were acquired. In the future, CPC will continue to expand its renewable energy deployment. In 2025, the goal is to reach a total installed capacity of 25.365 MW (with an additional 4.135 MW of renewable energy generation capacity), demonstrating CPC's determination to actively support policy-driven energy transition and contribute to the development of green energy in Taiwan.

Water consumption and management

CPC has developed a comprehensive water resource management system and adopted a diversified water resource utilization strategy to address the impact of climate change on water resources from two perspectives: “water recycling and reuse” and “access to water resources.” Following the implementation of water resource management, all uses of water are subject to water impact assessment and do not pose any material impact on the water source. 

Water usage and impact assessment 

To enable better control over the water constraints and risks of water usage at various plant sites, CPC has adopted the water risk assessment tools developed by World Resources Institute (WRI) and devised water risk management strategies after taking into consideration the local water resources, stability of water supply, regional supply and demand, and risks of water usage identified for critical operations and sites. Using the WRI Aqueduct Tool, CPC considers the stability of water supply and regional supply and demand to be of low risk at critical operations and sites.
