As a high carbon emission energy industry, CPC's main guiding principles for promoting environmental protection are as follows:
In order to fulfill its commitment of environment and ecological conservation, CPC's Environmental Protection Division changed its name to "Environmental Protection and Ecological Conservation Division" in 2018. The division established the Ecological Conservation Executive Committee, while setting up special environmental protection teams in each department to establish an integrated environmental management system. In line with the policy direction and the trend of convergence with sustainable development, CPC have added the key points of environmental organization management, required each unit to set up designated staff, set up a website for environmental documents, and provided an internal and external complaint mechanism. In addition, CPC required all supervisors to finish professional training in environmental protection and implemented regular review meetings to examine the implementation progress with the purpose to achieve CPC's environmental management policies related objectives.
GHG Management
In response to the international trend of the mitigation of climate change, carbon reduction goal and enhance the competitiveness of the green economy, CPC has followed the national policy to set GHG reduction targets and continuously tracked emissions through GHG inventory. In line with the national long-term GHG reduction targets, CPC introduced the ISO 14064-1 GHG inventory system in 2004 to conduct annual GHG emissions inventory, which the refinery emissions are verified by third-party certified by the EPA. Based on which GHG reduction targets, GHG management plans are promoted to reduce GHG emissions.
In line with the national carbon reduction target of the Greenhouse Gas Reduction and Management Act (GHGRA) announced by the EPA, 50% reduction of GHG emission compared with 2005 needs to be done by 2050. CPC sets 11.58 million tons (CO2e) emission of 2005 as the base year emissions and conducts an annual GHG inventory in Scope I and Scope II based on the management table of GHG coefficients announced by the Environmental Protection Administration. Self-site (plant) coefficient will be used first, and the GWP value will be adopted according to the regulations of the Environmental Protection Administration. CPC's GHG inventory operations are conducted by the operation control method, and the results are expressed in terms of CO2e. In 2020, GHG emissions were reduced by 1.04 million tons of CO2e compared to 2019. Since 2016, the GHG emission intensity has shown a decreasing trend for three consecutive years. GHG emissions intensity in 2020 was increased by 22.5% compared to that in 2019 due to the 29% decrease of revenue resulted from COVID-19.

Note 1: CPC does not use biofuel.
Note 2: The upstream and downstream supply chains of CPC are extensive, and it is difficult to a certain extent to carry out the inspection on the supply chains. However, as CPC is currently conducting an ongoing supply chain inventory. The quantification and verification of Scope III are temporarily not included in the emissions calculation.
Note 3: The 2020 greenhouse gas emissions were confirmed after the refinery completes thirdparty verification in July 2021; greenhouse gas emission intensity = annual greenhouse gas emissions / annual revenue (kg/NT$).
Note 4: In 2020, CPC implemented 58 energy-saving and carbon-reduction measures. Greenhouse gas emission intensity (= annual greenhouse gas emissions / EDC refining volume) is calculated as 0.039, which is better than the value 0.044 in 2019.
In line with the first phase of GHG emission control actions, CPC has been implementing a number of process improvement and energy management projects since 2005 to continuously reduce GHG emissions. The cumulative energy savings from 2005 to 2020 was 913,000 KLOE, equivalent to a carbon reduction of 2.669 million tons. Energy consumption had improved significantly across all major production units during this period.
Energy and Resources Management
CPC consumes electricity, natural gas, steam, fuel gas, petroleum gas, and fuel oils. The total 2020 energy consumption was 102 million GJ, with the highest heating value from fuel gas. In addition, the 2020 renewal energy output of our PV systems totaled 9.215 million kWh and were sold to TPC. The 2020 output production was about 180.245 million kL, with energy intensity at 0.566 GJ/kL, about 3.74% lower than that of 2019 at 0.588 GJ/kL. After energy conservation and carbon reduction programs are implemented, the unit product energy consumption was stabilized.

The capacity of renewable energy equipment at each business unit
In response to the Renewable Energy Development Act "Regulations for the Management of Setting up Renewable Energy Power Generation Equipment of Power Users Above a Certain Contract Capacity", there are a total of 6 business units to be regulated. The following table shows the obligation of setting up renewable energy power generation equipment by each business unit. The total capacity of renewable energy should be installed by CPC is 25.25MW, As of the end of 2020, 10.9 MW of rooftop solar power generation systems (excluding 709 kW for lease) had been installed; another 1.625 MW of energy storage systems had been installed or under planning.
